South Tower Work: - 3m ATI sonic zeroed and mounted - 3m fast T mounted and calibrated. This ended with a "zero" followed by 4 or 5 calibration cycles, which should have gone through the data system. - Veggie meter mounted at about 3.75m (as far as the cables would reach. It is set on the "middle" range (I think 20 micromoles/... full scale). This all done (in this order) from about 1000-1130 local.

We noticed negative voltages out of pile.pyg.in. Steve put a broom over it and found that the signal became less negative. He therefore reversed the wires, so it now puts out a positive voltage.
Now that the data system is running, new things to do are: - check veggie meter output - Today the display had a ratio of about 1 (4.8 for 660 and 4.6 for 730), but we were getting 4 and 15 (?) through the data system. [WORKED ON, BUT STILL NOT FIXED: see comment #12] - Something happened to the 10m Krypton this afternoon. We need to at least check cabling. [DONE: Thurs, day 24, ca. 1000 local. The SMC connector was a bit loose.] - The soil G's seem more different than I'd expect. Dailyplots should help investigate this (but depend on covar) - We need to call Cathy/Campbell about the status of the other krypton [DONE: Thurs, Day 24, ca. 1100 local. She is shipping today.] - I need to call Carl with a shipping accout number - I need to e-mail Carmen Nappo with a shipping address - We need to command the Gill to take in the fast T data - apparently it doesn't work to use rserial. We need to calibrate this sensor (fast T) through the data system. We need to compile and check my calibration routine to read these data (sonic_gill_2.c). [DONE: Thurs, Day 24, ca. 1400 local] - Bob Grossman and Jielun visited and want the veggie meter pointing to the NW at a more oblique angle (say 45 degrees). [DONE: Thurs, Day 24, ca. 1000 local] - Eventually, we should deploy the Licor. I should at least program the Crontrol. - I need to look at another differentiator channel. The top looks like white noise. The middle looked strange also.
Network travails:

Plan A
First tried this. All adams would boot except daisy. No amount of
cable polishing would enable daisy to boot. Tried a test with blazing
enabled on ragwort and cosmos. One adam lasted 1/2 hour, the other
about 3 hours.

Tried to separate adams into 2 networks.
Tried this configuration. Ran with this config from 12:35CST on Feb 23
to 13:41 CST. marigold and daisy archiving normal channels, daisy
running blazing. ingest on daisy died, but blazing kept running (Steve^2
were fiddling with serial channels - rlogin&rserial seemed to give problems.
Restarted archive & blazing on daisy at 14:15 CST.

At 13:20 CST connected cosmos to an ODS 241 host port with a short fiber
and booted it successfully, which means it was sending status messages and
the 2hz blazing averages to aster. Did not run blazing on cosmos though.

Plan C2
Couldn't get this to work. Adams wouldn't ping or boot.
It should work though. It is the same configuration that we
use out at Marshall to connect aster to the NCAR network, where
the ODS 239 is connected to the Marshall thicknet instead of coax.
Seems that the 239 cannot reach a 236 over 600m of fiber. ODS
documentation indicates that it should work, though their drawings
show an ODS 234 instead of a 239 (I'm assuming a 239 is the equivalent
of a 234, with a network tap instead of a AUI connection).

I just found a bad connector and another strange connector on the 730nm channel. After fiddling with it, it was left in the following state: - range was 0-20 - display on ratio - 660nm reads about 40.0 on the display, has voltage of 0.040 Volts - 730nm reads about 35 on the display, has voltage of 0.350 Volts Thus, the 730nm channel behaves as documented in the manual, and the nm channel is attenuated by a factor of 10. There is still more work to do to understand the output of this sensor.
WEATHER: Thin, broken stratus. No rain since we've been here (2/15). Wind N@6 m/s - have been stronger (13m/s?) earlier in the day. Dew forms on the ground in the morning, gone during the day. Soil is spongy on north-facing terrain, hard on south-facing. DATA SYSTEM: marigold: up, archiving cosmos: up, archiving blazing (10m hotwire data since 2250) ragwort: down - can't boot on .78 subnet daisy: up, archiving regular and blazing covar not written yet ppp not running yet (crashes pinot) SOUTH TOWERS: hw.3m: not installed (waiting for stuff from Carl Friehe) hw.10m: running, but wired into cosmos (hw.3m). See field notebook for more details. (needs to have a filter, which will come from Carl). t.3m.S: OK, cals done today h2o.3m.S: sent from NCAR to Campbell today t.10m.S: OK, cals done today h2o.10m.S: OK now, the SMC connector was loose overnight last night licor: not installed aspirated vais: not installed tsoils: OK Tsurf.dark: OK, cable problem fixed yesterday (Teast was bad) pygs: OK now that pile.pyg.in wires were switched yesterday; comp, case, and domes are all about equal psps: OK net: OK Gsoils: working, values are more different than I would have expected; maximum rates during the day were about -100, -80, and -40 for G.3cm.A,B,C respectively, and about -35 for G.8cm. The sites are: A - furthest East (near darkhorse), B - central, and C - furthest West Veggie meter: Turned off. Was running from about 1600-1640 local, but cables were disconnected much of the time for testing. 660nm appears to be low by a factor of 10. Tsurf.port: not installed - waiting for Larry and Jielun rain.ORG: up - no rain atik.3m.S: up, spikes in data probably were during fast T cals atik.10m.S: up, spikes in data again from fast T cals props: look good - 10m crashed during the day, but cycling power revived it. psycs: okay - 5m appears to be about 0.05 C high now, RH's have been within 1% generally. float has been at 2m since yesterday afternoon (from 1m earlier), for comparison to the others. baro: OK. The port was installed at 2m, rather than 3m. We'll move it tomorrow. NORTH TOWERS: hw.10m: not running (need a differentiator from Carl) gill: up. Now programmed to digitize one analog channel t.gill: OK, calibrated with an offset of 6.1C to fit better within the gill A/D range props: OK now, 5m prop died earlier today (like the 10m.S), but revived with power cycling. psycs: working, 3m RH appears to be about 8% low now!
the roving psyc (serial# 68) was swapped with the psyc.3m.N (serial# 67) at 16:47 due to a 8% low humidity reading psyc serial # 67 was then checked out for possible corrupted cal coef. and obvious humitter problems, (not successful) and reinstalled in the roving psyc slot at 18:45.
To conform with the configuration specified for this program. unit moved at 16:30
A test was run on the channels used for the aspirated humitter (bazooka). A gain setting of 5 was used. There was no sign of the zeroing circuit affecting the signal. We will use this configuration for the bazooka.
We are going to adopt a sensor-based sign convention for the pyg and psp radiation signals. We are doing this because data from the new pygs is difficult to interpret in the field with all of the sign reversals. We are now switching the wires back on pile.pyg.in (since it should be negative, with the sky colder than the case). I have just changed the cal_files pyg.out and psp.out to remove the negative sign, and will update the ranges on the cockpit plots for these variables. We will need to modify the sumrad dailyplot (and possibly rad.config.S) to incorporate these changes.
I've just changed jumpers 16-17 to 17-18 on the Datel boards on both cosmos and ragwort. This was done since the hotwire bridges from Carl give voltages over 5V in the high winds we have been getting. We could use Carl's buck&gain units to compensate for this, but they aren't here now and it doesn't hurt to have +/-10V anyway.
WEATHER: Clear. Winds have been steady from the S at about 3-8 m/s. DATA SYSTEM: marigold: up, archiving cosmos: up, archiving blazing (function generator ramp at .25 Hz) A/D range set to +/-10 V ragwort: up, archiving blazing (10m hotwire data since about 1900) A/D range set to +/-10 V daisy: up, archiving regular and blazing SOUTH TOWERS: hw.3m: not installed (waiting for stuff from Carl Friehe) hw.10m: running.

See early logbook entry. psps: OK. sign of cal of psp.out changed to +. net: OK Gsoils: working, values about like yesterday's. Veggie meter: Didn't run today. Still should have problem on 660nm. Tsurf.port: not installed - waiting for Larry and Jielun rain.ORG: up - no rain atik.3m.S: OK, no obvious spikes atik.10m.S: OK, no obvious spikes props: OK psycs: OK, float (mounted at 2m) RH still about 10% low. (calibration coefficients were checked with Cathy and were okay). We'll put a new unit in when Ned brings one. baro: OK. The port is now in 3m. NORTH TOWERS: hw.10m: not running (need a differentiator from Carl) gill: OK no obvious spikes t.gill: OK props: OK, a few spikes (dropouts?) in 10m.N. This will require further checking. Are these at 5 samples/sec? psycs: OK, RH compares well after the swap with float
WEATHER: Clear. Winds S@8m/s. DATA SYSTEM: marigold: up, archiving cosmos: up, archiving blazing (function generator ramp at .25 Hz) A/D range set to +/-10 V ragwort: blazing died overnight at 0752 for reasons unknown.

As I recall, we decided that the props were capable of giving good data at the higher data rate, but when we tried it during CACHE we saw more dropouts (which was thought to be caused by the ADAM). I'd like to try this again. Furthermore, we saw a couple of dropouts on the prop.10m.N yesterday, which may be easier to detect at the higher data rate.
about 5 minutes ago
We just put new batteries in Tony's headset unit and got a range of only -200m. This isn't enough to go from the base to the South towers. Too bad...

For some (unknown) reason, the 660nm channel really is reporting a voltage which is low by a factor of 10. Perhaps RAF modified for aircraft use. I've just changed the gain in prep.config & .raw on this channel. Making the change this way will cause the 660 channel to have more noise than the channel, but both should be okay. The range switch is in the middle position, 0-20, which actually is 0-3000 on the 660 channel and 0-300 on the 730 channel. These values are in umoles/m^2/s (I think).
Over the last 2-3 days, we have had several unexplained ragwort crashes due to a breakdown in communications between the ingestor and ragwort. "ping" reported today that 19% of packets were lost. Therefore, we just reconfigured the network again to have ragwort directly connected to the .87 hub via fiber. ping now shows no packets lost, but we'll see if it continues...
To overcome timetag errors on several ADAMS, we checked power settings on the fiber hub. We noticed mismatches between High and Low optical power on the line to aster and marigold. We now have checked that all 236 modules (except daisy's, which we assumed was H) match the power setting of the hum. We also swapped in a new cable to cosmos. We now have (after swapping marigold yet again): Hub port node Optic power Length of cable daisy H 3x100m marigold H 100m aster H 2x300m cosmos L 100m ragwort L 30m (grey zip) With this set up, all adams ping with 0% packet loss, though marigold sometimes still loses a packet or two.
I've just deleted the following raw data files since they were small (less than minute of data) and thus probably were due to bad time tags. north: all053213530 south: all053191344 all054022640 all054112812 all055000910
Since it isn't up, the bazooka channels: (t,rh).vais.2m.S are not being archived yet. They also are not being covar'ed. Remember to change this when it is installed.

Fetched patch 101969-05 from steam. It is supposed to fix dp 3.1.2 on Solaris 2.4. Installed it on pinot. It didn't help. pinot connects to steam, and you can ping steam with no packet loss, and with transit times of around 260 ms, but telnet/ftp/rlogin don't work.
Marigold was not sending data this morning. dataGet and recDatel had suspended themselves. The sync process was still sending status messages, so archive was still running, but only the status channels were being received. Rebooted it at about 14:15 GMT Instead of suspend, the adam might as well do an mxreset - though this could cause problems when setting up the network. If the network is not in good shape the adams will keep rebooting themselves. We should set a global variable in the startup.cmd scripts to control whether the adam reboots or suspends when the dataGet routines notice that they're running out of memory.
Cocklebur sounds terrible. I opened up the chassis and determined that the noise is from the muffin fan and not the disk, so we'll let it continue.

We are running the UPS in its battery backup mode, but it screams every few days that the charger has been off too long. (The charger is set to "auto", but never turns itself back on - probably due to a problem with the UPS which Kurt will check out.) The procedure when it beeps is: Press: CONTROL CHGR CHGR (should see "Auto->Eqlz", if not keep on pressing CHGR) Press: ENTER ENTER The alarm should turn off, and battery equalizing should start again. Expect the alarm to go off after another 4 days or so.
Over the past few days I've made quite a few changes to software on ASTER and the adams. . Ingest. Ingest was not handling partial sample reads correctly. I believe this has always been a problem, but in a normal deployment the situation was very rare, and so went undetected. On a stream socket, even though the adam writes complete samples on the socket, ingest may not read receive the entire sample in one read - especially if the network is loaded as it is on this deployment. Ingest now makes no assumptions about being able to read more than 1 byte at a time. . VxWorks mbufs. The defaults settings (in $ASTER/vx/h/net/mbufs.h) were: #define NUM_INIT_CLUSTERS 4 /* number of clusters to initialize */ #define NUM_INIT_MBUFS 40 /* number of mbufs to initialize */ They are now: #define NUM_INIT_CLUSTERS 20 /* number of clusters to initialize */ #define NUM_INIT_MBUFS 100 /* number of mbufs to initialize */ I used mbufShow on an adam to determine these parameters. See logbook entry 24. I doubt these settings actually improve things much, since the network buffers are never de-allocated. Once the adam is up and running for a few seconds, the required network buffers should have been allocated, and these parameters are not relevent. . SOCKET_BUFFER_THRESHOLD in $ASTER/adats/rpc/sync_sample.cc was increased from 1024 to 4096. Samples are assembled until the accumulated size exceeds this threshold, and then are sent in a group. . socket buffers sizes have been changed from their defaults on the adams and on aster. sync_sample.cc socket to ingest SO_SNDBUF 4096 + 3 samples ingest.c socket from adam SO_RCVBUF 4096 + 3 samples rdisk_start.c socket to blazeArch SO_SNDBUF 19250 blazeArch SO_RCVBUF 19214 + 64 . Priority of ingest and blazeArch. These programs are now started from scripts, which are setuid to root, ie: when they run they have root's capability to increase their priority. The priority of Ingest and blazeArch can be viewed with ps -elf The NI (nice) value should be 10 and the PRIority should be around 40. ingest is a script on $ASTER/scripts which executes Ingest. blazeArch.sh is a script on $ASTER which the adams execute when they start blazing. An "ls -l" should show that they are owned by root, and "rws" for the owners permission: cd $ASTER ls -l blazeArch.sh -rwsr-xr-x 1 root aster 259 Feb 26 20:11 blazeArch.sh* cd $ASTER/scripts ls -l ingest -rwsr-xr-x 1 root aster 323 Feb 26 20:09 ingest* To set the scripts to these permissions: su chmod 4755 blazeArch.sh . When Ingest has detected that an adam has booted, it executes a adam_name.up script on the project scripts directory, for example "ragwort.up". You can put anything in these scripts. Here's the current contents of ragwort.up: #!/bin/csh -f # Script which is run automatically by ingest when an adam comes up. sleep 30 archive_ragwort sleep 10 blaze disk on ragwort aster sleep 10 covar_ragwort sleep 10 cockpit ragwort So ASTER can almost operate by itself!!! . Added a global variable to the Matrix code, called rebootOnError. If this is set the adam will reboot instead of suspending a task when it detects a lack of memory to malloc.
Even though Tom told me not to, I've just put my version of sumrad.S (which should deal with the pile signal and different sign conventions) into $ASTER/apps/sfun/util. I saved the old version as sumrad.S.preMICROFRONTS in case we need to go back. I needed to do this since $ASTER/.Data is first in the Splus search() list, so a "private" version in $ASTER/.Data/MICROFRONTS95 was never being used.
THE PAST Ned arrived and set up CLASS/met with temporary who will be the operator. Q7 installed. It was hard to level, but I think I improvised a mount which got it close. This isn't the best weather to compare (solid overcast and drizzle), but the Q6 and Q7 read about 20 and 28 W/m2, respectively(?) so I think I got it hooked up okay. Filter module installed in ORG.700. This was an oversight, which caused all rain plots to date to be bad and made us miss the rain event early yesterday morning. The veggie meter battery appears to be the worse for sitting out in the rain. We need to mount it better (in a baggie?) and probably replace it. nd Toshiba taken out to North towers, so we can communicate from there. Lots of work getting daily plots running. I made mods to sumrad to read pile.pyg, to Tsoil plot to use color and to accept a did name of "Tsurf", and maybe to one more. I also spent a lot of time renaming archive files to compensate for erroneous time tags - mostly in day 57. This was needed because covar got confused and would not show data in the daily_plots. Gordon spent the day working on the blazing archive script and trying more methods to prevent data loss. (We still had 2 marigold crashes in the last 24 hours, and blazing appears to be losing buffers and time.) Yesterday, he implemented neat code to startup archive, covar, and cockpit every time an ADAM boots. No more lost data!(?) We still don't have ppp running, but one of our phone lines is down anyway and the other isn't very good. We need to examine/repair the cable splices. Carmen Nappo showed up and installed his microbarographs, but needed some cable and a power supply to get it all running. THE PRESENT Known problems: - The props at 3m.S, 10m.S have zero speeds. 10m.N, and others to a lesser degree also have dropouts. Matt showed up today and I've asked him to look into this problem. - Float psyc reads 4% high these days and 3m.N reads well over 100%. We can swap in two new psycs delivered by Ned. I noticed that the boom connector had blue corrosion in it, which will need to be cleaned better than me blowing on it. - I think Steve didn't complete the cal_file for t.gill.10m.N. I need to check on this. THE FUTURE We need to install the hotwires. I will try to repair one of the empty probes. Carl Friehe's stuff arrived in the motel tonight. We need to start taking soil samples. Ned brought the oven and scales. More work is needed on the blaze archive scripts.

Notes:
. Data ingest process notices that the ADAM is crashing.
. The archive process receives read errors and quits.
. ADAM has rebooted and has contacted the ingest process. A new ingest
process has started, with process id of 22231. This ingest process
executes the .up script for the ADAM. For daisy this script is
$ASTER/projects/MICROFRONTS95/scripts/daisy.up
. The .up script first starts the archive process which opens a ingest STREAM
socket.
. The previous blazing archive process (16568) finally notices that
the ADAM has rebooted, and quits.
. The .up script starts the blazing archive process.
. The blazing archive process opens an output file.
. The .up script now starts covar, which opens the 2nd STREAM socket.
. When the .up script exits, the Ingest process receives a SIGCHLD signal
and reports this error. This is harmless.
.The .up script starts cockpit which opens a DGRAM socket.

Perhaps, weighing hot soil cause scale measurement errors.
This may have repeated work that Steve did: reading in Steve's ../raw_data/north/tmp file, and manually picking out the calibration periods resulted in a mean difference of 5.044 degrees, using the default calibration of 1 count = 1 mV and 1V = 10C, and an offset of -6.60. This implies that the gain should be: .001 * 10 * (5/5.044) = 0.00991 and that the offset should be -6.60. cal_files now has: 0.009996 and -6.1. I'll change these number to the above calculation. (But, they are small enough that I won't deliberately restart covar - Gordon is rebooting daisy now anyway.
Yesterday Matt found that 3m.S could be revived by scraping solder flux off the chopper assembly and greasing up the vane part of the head to cut down on the entry of moisture into the head. We started today with 10m.S giving zero speeds and 3m.N and 10m.N not giving anything. We had known that we wanted to work on 10m.N anyway since the wind directions yesterday were bad. We pulled down 10m.S, breaking the prop in the process and brought it into the trailer for servicing. Matt did his magic, and it recovered and ran all afternoon outside the trailers. We found that the vane had come out of 10m.N (apparently I had forgotten to install the screw(?!) and the vane was lying on the ground. I replaced the vane and gooped it (and 5m.N and 3m.N) up. We also cycled power on m.N and 3m.N, which revived them. However, 10m.N still gives funny directions like yesterday, and probably needs to have another boom alignment done. In the meantime, 3m.S gave zero speeds again. Since 10m.S was now working, we installed the old 10m.S at 3m.S and pulled 3m.S into the trailer (again!), where it now is. More on this saga tomorrow...
This is quick, since I never had time today to do an official status. We spent much of the day working on props (see prev. comment) All the fast T's broke in the snow which started about 10AM (local). As of this writing, it is still lightly snowing, with about 2 inches (drifts in spots) on the ground. Because of the snow, no hotwires are deployed.
Since all 3 fast T's were broken, we replaced the one at 3m (more freezing rain is expected in the next day or two). I tried a calibration, but could only get a gain difference of 4C, instead of 5, after zeroing. I did a calibration cycle, so we should be able to track this.
WEATHER: Low overcast. About 3 inches of snow on the ground (fills furrows, but grass still protrudes). Cold: -10C. Winds NE@4m/s. DATA SYSTEM: Data from all adams stopped last night due to a network problem. Mxreset brought everything back up marigold: up cosmos: up, (0.25Hz ramp on both channels) ragwort: up, (bridge/derivative turned on, but no probe) daisy: up, (nothing connected) Still have days 56-present(61) on disk. Blazing tape archive script not running yet SOUTH TOWERS: hw.3m: needs to be wired, probe and holder installed hw.10m: broken, needs to be replaced t.3m.S: OK - just replaced (gain = 4, see previous comment) h2o.3m.S: waiting for Campbell to send back t.10m.S: broke during snow yesterday h2o.10m.S: ?.

(0.25V still piped into the rh channel) tsoils: OK, suspect that t.1cm.soil.A is exposed to air Tsurf.dark: OK, no strange values on Teast recently. pygs: OK - domes may not have been iced yesterday since fans were on (they were noisy, so we could here them) psps: OK net: OK Gsoils: working, 3m.A again (like T.1cm) appears to be closely connected to the air Veggie meter: Off now. Tsurf.port: not installed - waiting for Larry and Jielun rain.ORG: OK - showed the snow yesterday atik.3m.S: OK, a few spikes. The yoke shifted while I did the fast T installation, so I retightened it, however the level definately shifted. atik.10m.S: OK props: 3m.S (old 10m.S) OK, nothing now installed at 10m.S. psycs: OK baro: OK, we see a 0.15mb noise level in the spectra NORTH TOWERS: hw.10m: not running gill: OK no obvious spikes t.gill: OK, cal_files entry altered last night props: OK, 10m.N has strange direction problems. Others OK psycs: OK
The yoke for atik.3m.S was loose, and shifted when I calibrated/installed the fast T. I tightened it, but the level signals (on cockpit) obviously show that I changed the pitch (from 0 to -1 degrees).

WEATHER: Overcast. About 2 inches of snow on the ground (slowly melting). Somewhat warmer: -3C! Winds lighter also: SW@2-4m/s, sometimes even calm. DATA SYSTEM: Gordon was working on things until 2AM? last night. Normal archiving stayed up, blazing died since the disk (/blaze) filled up, but had lost NO buffers of data until then! marigold: up - lost analog only data yesterday for some unknown reason (we think cockpit was getting data!) cosmos: up, (nothing connected, since working on Carl's bridge #2) ragwort: up, (nothing connected) daisy: up, (nothing connected) Just archived days 57-61. Blazing tape archive script is running. Gordon has archived the old data. Gordon suggests looking at blazelog/hw/ files to check buffers lost. cosmos and ragwort lost 5 and 6 out of 20000 and 28000 buffers respectively.

It would have been offscale a lot of the time anyway. props: OK, 10m died, has been pulled into Matt's prop hospital psycs: RH, 3m has behaved erratically the last few days - sometimes good agreement, sometimes off by by 12%. OTHER: Johnny-on-the-spot cleaned out for the first time (in 2 weeks) today! Fixed leak in sink. Matt got us stools for the chem trailer yesterday dp now running! We can talk to steam!

Replaced the FLOAT psyc with a new one because the old one had humidity readings a few percent (2% - 5%) high. Old unit #67 New unit #2
I have been concerned about strange temperature profiles from the psycs on the S tower. They have consistently shown cooler temperatures in the and 10m data (also 10m.N), than the data from the lower sensors. After playing with dailyplots, I get more consistent profiles using the following biases: t.psyc.5m.S: 0.03 C high rh.psyc.3m.S: 1% low rh.psyc.5m.S: 0.5% high rh.psyc.7m.S: 1% low rh.psyc.3m.N: 2% low rh.psyc.10m.N: 1% low These numbers give good looking profiles for day 63, though still not terrific for days 61 and 62. We will continue the intercomparison using "float": place a second "good" psyc at each level for a day. Unfortunately, the psyc Matt installed yesterday doesn't seem to be very good, and we may need to start over again.

We replaced the fast Ts in 10m.S and 10m.N. Also, because I was suspicious of the cal of 3m.S, I redid its cal also. m.N: ~0900 local, 1500 GMT m.S: ~1654 local, 2254 GMT (this was much later because the probe I had indended to use fell out of the tube and broke in my pocket. I had to make up a new set of spares.) m.S: ~1702 local, 2302 GMT. Unfortunately, I adjusted the offset from about 1.5C to 5.1C before realizing that I should have done another calibration. I did a quicky cal after this adjustment anyway, and then did a full calibration after completely readjusting. The bridge was quite out of adjustment (gain 4.2?), so it was good I redid the cal.
I still want to do a "roving" calibration of the psyc profile, so I want a good "floater" unit. We just put in yet another, which is working, though the RH is still several % low. Hopefully, the RH sensor is "aclimating (sp?)" and will be better tomorrow. The swap was done about 2000 UTC.
We reinstalled prop.10m.N about 2015. Matt climbed to prop.10m.S, but it was working by the time he got there. It likes him! We decided to leave it in place for the moment.
WEATHER: Strato-cu all day with occasional breaks. Only a few snow patches remain - there are some puddles in the ruts. Somewhat warmer. Winds moderate. The forecast still is for an ideal artic front to come through sometime tomorrow. DATA SYSTEM: marigold: up - lost analog only data yesterday for some unknown reason (we think cockpit was getting data!) cosmos: up, I just connected it to powered-off hotwire electronics ragwort: up, I just connected it to powered-off hotwire electronics daisy: up, (nothing connected), I stopped daisy blazing archiving about this time last night so that the disk wouldn't fill up with garbage data. daisy crashed this afternoon (2145) while we were out at the towers for some unknown reason. We are now running Matt's new blazing tape archive script which only uses one tape drive. In the last full archive file, rawort and cosmos lost no buffers!

OTHER: one phone line is dead again!
Since w was giving spikes, I blotted water from around the transducers on atik.3m.S. I noted that most of the water on the w-axis was surrounding the rubber o-ring around the BASE of the bottom transducer. There also was a fair amount of water dripping down over the edge of the top transducer. cockpit is showing less spiking, though I'm not sure that it is fixed. (I should check plot.prep) I wonder if the spiking is caused by a short from the transducer shell to the array arm - if so, this could be fixed with a bit of RTV P.S. w started spiking again 45 minutes later - maybe I'll try my RTV theory. P.P.S. blotted again about 1445, this time put sleeve over bottom w transducer (though it had several drops of water on the face also).
All of the upward-looking radiometers had water on the domes. I blotted both of the nets, since I was already there with the stepladder. I decided not to reach out to get to the psp or pyg. I thought that the fans were supposed keep these clear. (It looked like the West side of the west unit (psp?) was clear, but the east side was wet - perhaps the flow is stronger from one side.) The problem I originally went out to fix - Q7 leveling did not have to be done since the Q7 was already PERFECTLY leveled!

Modified Gordon's script to work with the one working high density tape drive. See the BlazeAuto.csh script for specific details, but the gist is once the script is started it just keeps going and archiving files. Usually the archive runs every hour at xx:05 for about 20 minutes grabing the latest file. However, if the archiving has gotten behind, then the script will run continously until it has caught up. Every 12 hours, the tape pops out, a label is printed, and a message pops up on the screen requesting a warm body to replace the tape. the script waits until someone clicks on "OK" before continuing. The timing is such that the message will appear about 7:25 am CST and 5:25 pm CST. Presumably someone will be in the trailer around 8 or nine-ish to change the tape. If the process stops (do an "at -l" to see if it is scheduled to run), then make sure you start it with the oldest file which has not yet been backed up. TAPE ORGANIZATION NOTE: Previously, files xxddd001... to xxddd011 were stored on the am tape and xxddd013 to xxddd023 were stored on the pm tape. This has changed starting on JD 65 to work around more reasonable personnel scheduling. the am tape stores xxdda021... to xxddb007... and the pm tape stores xxddd09... to xxddd18...
The rain just changed to sleet - we could hear it on the roof. P.S. The sleet has killed both 10m fast T probes - hang on 3m.S!

Since there was little else to do in the rain, I carried all of the CO2 equipment out to the shelter and started setting it up. The Crontrol is running - I think with a 10 minute cycle: 5 min on/5 min off. The pump is connected, but not turned on (the fittings need to be tightened with a wrench - only hand tight now.) The sample line is not connected, nor is the soda lime zero chamber.
Previously the hot wire tape backup was running with "medium" density. Last night discovered that the last files on the hw065.am and hw065.pm tapes were not being saved because the tape ran out. Fortunately these are tapes with dial-a-volt fake data, not real data. I changed the blazeAuto.csh script to use "compressed" density. This seems to have worked, in that the hw066.am tape didn't lose anything. I didn't change the blaze2Tape.csh script, since we aren't using it now. Based on tests Steve O. and I did a few days ago, the compressed format "/dev/rmt/0cbn" can hold 10 files of real hot wire data. We thought that the "/dev/rmt/1mbn" format was saving the same amount of data, but based on current experience, it only holds 8 files.

I've just connected everything up as I think it should be and have powered up the licor and pump. The pump flow rate is at about 6.5 liters/min. In theory, I have the zeroing set up to occur every 15 minutes, from :00-02:30 after the 15 minute. I tried to synchronize the Crontrol to aster time, but may be off.
Aster was temporarily halted to allow us to remove the bad tape drive /dev/rmt/1 This required stopping all processes on the ADAMS. cosmos and ragwort had to be switched to reboot, daisy and marigold mxreseted okay. Everything appears to be running again now. Note: we didn't reboot aster, so the low density drive is still /dev/rmt/2. It may change to /dev/rmt/1 if aster is rebooted.

Matt is working on the phone lines now.
We finally got a hotwire going at 3m.S about 1/2 hour ago. Initially, it was offscale since we had the buck&gain sign wrong. I've just switched it to buck=+5V, gain=2, which should give a range of -10 to +10 for an input range of 0-10V. The wire probably will operate in the range of 3-6V which will come out as -4 to +2V. I set the cable resistance to get the probe to balance at about 8.5ohms, and also adjusted phase and cable capacitance on this bridge (#2) to get a decent signal from the square wave test. The filters are set at 5KHz, no buck and gain on the derivative signals (yet - we may decide to put them in if necessary later).
I installed a probe about an hour ago, but didn't adjust it until about 15 min ago. I put a cal cycle in the data stream after adjustment (which was a pain since the temperature was about -4C, so I had to keep track of sign reversals.

Since I've noticed a higher-than-normal noise level on w.atik.3m.S, I've adjusted pot RP1 on the w-axis board. I lowered the gain by about a factor of 2 by turning RP1 about 1/3 turn counterclockwise. This adjustment should be done in zero wind, which is impossible today with m/s winds. However, I did notice that the output of w now looks like u and v.
Since the krypton signal level was low (ashow gave 3000 = 0.5V), I cleaned it. ashow marigold 103 now gives 10,000 = 1.5V. I also noticed that the data cable from the krypton electronics is quite tight, and is easy to kick when climbing to service the 10m sonic/fast T/etc. I pulled a bit of slack on it, but this should be done better. A problem with this cable may explain the dropouts we observed last night.

There have been two incessent problems with the prop vanes. The first is speed dropouts and the second, although less of a problem, has been wind speed spikes. Here are some solutions to try and deal with the problems. WIND SPEED DROPOUTS I have tried various fixes to solve the dying prop vane syndrome. Seal vane to head attachment with lithium grease to prevent moisture from getting into the speed encoder electronics. This has been done to all three props on the north tower, and the 10m prop on the south tower. Install small bag of dessicant inside speed encoder. Essentially, I cut a 2"x 2" piece of paper towel, poured dessicant in it, rolled it up and then put electrical tape on the ends. This has been done to the 10m north tower and the 10m south tower. Clean solder flux off board. Did this to the 10m north tower. The m south tower also has some flux on the board but has not been cleaned. Clean corrosion off electrical contacts on vane axis. To get to this area, remove the horizontal electronics housing from the prop vane. Detach the wiring harness from the board so that it is free to spin. Then unscrew the vertical tube. The contacts are right inside. Alcohol and Q-tips seem to get most of the gunk off. This was done to the 10m north prop vane. The spare prop vane was checked but had no crud on the contacts. Remove dust from photo-diode detector. The detector is hidden under the plastic sleave. I unsrewed the main circuit board to gain access to the hole and just squirted dust-off through the hole. Did this to the 10m north tower and the spare unit in the trailer. Result of all this is the 10m north prop vane works, and the 10m south prop vane dies sporadically, but then comes back to life (something that did not originally happen with a dead unit). Looking at temperature and humidity plots from day 67 and 68 seems to indicate that the dying and reincarnation of the prop is more closely correlated to rises and falls in humidity than it is to temperature. I suspect that removing the dust is the key factor in fixing the problem. WIND SPEED SPIKES Have seen occasional spikes on all the prop vanes via the cockpit display. This is probably due to oscillation from noise (static buildup?). The speed encoder circuit is supposed to deal with noise via hysteresis, but the circuit can handle power supply voltages from 5V to 15V. The amount of hysteresis goes down with power supply voltages, and most likely the circuit is usually powered at 12V. Thus using 5 volts gives less hysteresis than normal. By changing R6 (which is on the back of the circuit board) from 10K to 33K, the hysteresis can be increased to 1 volt. The spare sensor has been modified in this manner, but none of the installed sensors have been touched.

The surface near the south array was examined. There is still some small expanses of surface water and the soil generally is still saturated. The dead grass stalks and leaves of approx 25-30 cm is flattened to a mat 7-10cm thick. There is some showing of green new growth but only a sprout every 10-20 cm. Three meters north of the intersection of the walkways a 50 cm x 50 cm section of the surface was harvested of dead grass. This was weighed with its ambient moisture content and was found to be 280 g (= 1.12 Kg m-2) This sample will later be weighed both wet and dry. The surface of the mineral soil was covered with a 2 cm thatch of matted vegetative material and within the quarter square meter section the surface of the mineral soil was irregular on a 20 cm scale to the extent of 1 cm. A trench was dug 10 cm deep in the soil. This surface layer was a sod with intertwined roots. Using a spade, a block of soil, with just the scalped grass cover, was dug from the harvested section. This block was trimmed and loaded into a plastic box. The block was measured and , the next morning, weighed at the UPS on a scale. Dimensions: 12.5 cm deep x 27 cm x 27 cm = 9112.5 cm3 weight: 37lb 6.5oz(including box, to be tared later) ~ 36 lb ~ 16 Kg bulk wet density = 16000/91125 = 1.76 g cm-3 The block of dirt will be allowed to dry out and will be weight when dry.

At approx 1915, 1315 local, the original board was carried out to the S array Using the new bottomless tent technology the substitute board was removed and the original board reinserted, dispite the rain. Inspection of the Marigold cockpit indicated that most of the sensor data was now coming in.
WEATHER:
It rained last night but by the morning the rain became spasmodic with
only occasional showers. The sky is overcast. There are light winds. It
is warm. For the first time the birds are singing.
GENERAL:
Yesterday there was persistent rain. There was standing water on the field
around the trailer and around the instrument shelters at the south array.
Many of the sensors showed missing or bad data input. The data situation
was made worse because the replacement amplifier/filter board which had been
substituted in Marigold on Sunday evening caused problems for its own channels
and possible for other channels. We could not remove it as it was raining. At
local time yesterday we erected a bottomless dome tent over Marigold,
opened the ADAM and replaced the original amp/filter board. The rain eased
in the afternoon and the general sensor/data system improved.
The telephones were dead(and have not recovered yet this morning)
The trailer began to leak around the air conditioner in the computer trailer
and down the wall behind the soil oven. We opened the power conduiting to
rearrange the electrical power leads.

North Tower: ~21Z Removed the Prop/Vanes from 3 and 10-m because they choked and died during the heavy rains experienced during the last two days. ReInstalled ~24Z Sensors were working. Problems were water in the connectors.
Phone lines have been down since Monday when the rain began. Walked line: found 3 new locations where the wires have been nibbled. Todays totals: 9 total breaks, 6 baggies, 3 without. suspect that 2-3 of the baggies got wet and shorted. Need to get cellular service.
~20:30Z Swapped PSP in and out cables in order to determine whether or not the PSP-out offset is being caused by the sensor or the A/D system. Both PYG aspiration fans, those wonderful Micronel beauties, are dead.
CO2 sensor has been down for 2 days. Retrieved from shelter. Front panel display showed: -11.6 output, 7 liter/min flow rate.
South Tower ~17:15Z Took down 10-m Prop because it's been reading low ever since the rains 1-2 days ago. In the lab, it's functional. Matt's desiccant inside the encoder housing is saturated. Blew out the encoder assy.
South Tower ~17:30Z Inserted hot-wire probe. Noticed some water inside the tube. Jielun tried but couldn't balance the meter. She also tried to reseat the sensor, but still no luck. No data coming in on cosmos.
The intermittent printing and batch problems we've been having seem to be related to the /tmp directory filling up. Purged old files from there, but we should probably reconfigure the system for more space. Without the system password though.... Meanwhile, will try to keep up with keeping the space clean.

At 2200 climbed the fast South tower and cleaned the Krypton hygrometer #1101 using water and a q-tip. This did not lead to any apparent improvement but I will wait til tomorrow to decide whether to bring the sensor down.
At 2200 attempted to balance the hotwire that was reinserted this morning. Switch to balance. Right hand balance indicator light on. Adjusted dial from ~8.5 to 0.0 and back to 10.0 with no affect. Tried cycling power on the balance module and repeating. No affect. Noted that there are trim pots on the panel but will seek advice before adjusting any of these.
At approx 2300 gmt John rebooted system. I cycled power on all four ADAMS.

We're going to leave the connectors for the time being to let them dry out and then we may tape them to improve the rain immunity.

At 1030 local the cables for the two psp's were returned to their proper config.
At ~1030 local teste the resistance of the 3m hotwire. The circuit was open. The 5 ohm resistance dummy probe was connected and a balance was acheived at approx 3.0 on the balance dial A new probe was inserted and its resistance determined to be approx 6 ohm. This probe was balanced with a balance dial setting of 7.4.
South Tower ~23:40Z on Thursday, 16Mar95 Installed the 3m Krypton #1133 just returned from Campbell. Ashow readings were ~10,000 and without new calib. in prep, the cockpit looks reasonable at ~8g/kg. Couldn't find correct cable for the 3m unit so used the one from 10m and lowered it down. That removes suspicion of it as culprit for the 10m problem. Tried Kr #???? 'down below, but its Ashow was still ~-400 counts. Returned it to trailer for now.
Operations were up this morning when we arrived, but... The daily plots did not go and mail indicated some problems with the s license server. Also, for some reason we discovered that the blazing archive was down overnight. Tony did have an 'abnormal' exit from an S session late last night as we left when he did a 'ctrl-\' exit from fun.plot.prep. That apparently must have left some residual S routines going that caused the subsequent problems. Before we discovered the problems noted above, we innocently resubmitted the dailys. Unfortunately, aster died shortly thereafter. The system did restart normally via a l1-a and sync. MXreset of marigold worked, but not for the others, but a hard power reset did work. Culprit was apparently the unattached S residuals.
We don't have a hotwire for the North array, and apparently little prospects of getting one soon. Therefore, to save some space and network traffic and overhead, the startup of blazing was removed from DAISY.UP in ~/projects/MICROFRONTS/scripts
After outages last night, the system reboot/restart this morning got the hotwire data going again for s3m. The first file is raw_data/hw/s3m076161805 NOTE, the blazelist log for hw076.pm doesn't yet show any files on tape or disk so we need to keep an eye on this so the data are properly archived.

The resistance of the wire (via the coax) was 158 ohms. There was water in the new Lemo connector. The other connector coax, power and bottom of Solent all seem to be dry. Removed the black bridge. Tested on the three at the S array-bad. At the trailer opened the black box to find several cc of water.
The 3m.prop.N failed this morning. On inspection at 1500 local showed water in the serial connector at the serial bob. The box was opened and found to contain water. The connectors were dried and the box reclosed. A new cable was substituted for the wet cable . The securement holes of the boom and the boom connectors were all taped with electrical tape.
The electronics of the Kr h2o' #1101 replaced yesterday was examined. Water had entered the electronics and corroded the power connector, and probably other componebts. John cleaned up the corrosion and then we tested the Kr h2o' #1101 head and the electronics substituting the two components sequentially in the replacement system. It was the head which did not work. We will examine it and probably send the system back to Campbell. UPS'ed Kr #1101 to Campbell on Saturday 18 March
South Tower ~0Z on JD77 Moved Krypton #1133 to more preferred position at 10m. Other Krypton #???? head is kaput and it may be several days before Campbell can fix and return it.

At approx 1530 local replaced old battery of Veggiemeter with new battery
At 1530 local time the aspirated Vaisala was reconnected to power. Inspection of before and after disconnection hot-wire power spectra density plots indicated that the fan vibrations did not affect the hot-wire response.
It was decided to sacrafice one of the soil temperature measurement sets
in order to investigate the insulation effect of the dead grass. The dead
grass protects the soil surface from solar heating and wind ventilation allowing the soil to remain moist and to reduce water flux even when the incoming
solar radiation is higa. This results in high sensible heat flux even when
soil moisture is high.
Soil multiplexer #3's set of four temperature probes furthest to the west,
were dug up and used
for this purpose.
In addition a soil heat flux plate was removed, and laid
in the hole - it's data should not be used.
The four temperature probes were installed under and in a mat of dead grass.
The 3 band probe was installed 1 cm under the soil surface
The 2 band probe was installed on the soil surface
The 1 band probe was installed 1 cm above the soil surface in the mat
The 0 band probe was installed on the soil surface in a short grass area
The Tsurf.a.port channel was connected to an Everest positioned 1.5?m above
this area viewing the top of the grass mat.

At approx 1530 local the two net radiometers were visually inspected for levelness. Both were level with their bubbles mostly within the 1 degree level circle. Both were adjusted to position bubbles withyin circles
The Tsurf.a.port channel was connected to an Everest serial ?? mounted .5?m above a long grass area viewing the top of the grass mat. This was connected to the data system at approx 1545 local time The Tsurf.b.port channel was connected to an Everest serial 135? mounted .5?m above a short grass area viewing the short grass and a portion of bare soil. This was connected to the data system at 1830 local time.

Got fast T on Gill working. When the Gill is power cycled it reverts back to its default, jumper configuration and no longer transmits the 5th analog channel. One has to send it the "55" command to tell it to output channel 5 as the analog channel. The trick is that the RTS line on the Gill (pin 4) must be held to +12V when commanding the Gill, and held to -12V for transmitting data in its normal mode. On the previous connector, the TX pin from the Adam (which is -12V) was wired to RTS on the Gill. I've now rewired this connector, so that TX from the Adam is connected to both RX and RTS on the Gill, and the +12V power is connected to pin 13, which is unused by the Gill. Gill Serial 9pin<->DB25 Cable Serial Cable 9 pin DB25 pin 1 Rx (Sensor to Adam) 3 Tx 2 Tx (adam to sensor) 2 Rx and 4 RTS 4 GND 7 GND 8 +12VDC power 13 Plug this cable directly into the Gill for normal data transmission. To send commands to the Gill via rserial, put this jumper box between the Gill and the cable: Jumber box for commanding Gill DB25 Female DB25 Male 2 TX 2 TX 3 RX 3 Rx 13 +12VDC 4 RTS 7 GND 7 GND Then connect to the Gill with rserial (rserial daisy 200), and enter "55" followed by carriage return. Do it several times to make sure. Then remove the jumper box, reconnect the cable and check the data. If the Gill is not sending the fast T analog data the last 2 bytes will be "82 82". If it is sending fast T data correctly the last 2 bytes will be varying.{author Maclean,Gordon} {title {t.gill.10m.N calibration {type FASTT} {date {Mon 20-Mar-1995}} {time {23:09:00 GMT}} {utime 795740940} {jd 079} {text \nDid\ the\ calibration\ of\ t.gill.10m.N.\n\nThe\ mean\ jump\ was\ 5.04213,\ so\ the\ gain\ should\ be\n\n5\ /\ 5.04213\ *\ .01\ =\ .09912\n\n\n\nHere's\ how\ to\ analyze\ the\ data:\n\n\n1.\ Edit\ \$ASTER/cal_files/t.10m.N.MICROFRONTS92\n\ \ \ Add\ a\ new\ record,\ with\ a\ time\ of\ the\ calibration\ time\n\ \ \ and\ a\ gain\ of\ 0.01\n\n2.\ Run\ prep\ on\ the\ archive\ file:\n\tprep\ -D\ t.gill.10m.N\ -f\ all079200000\ -j\ 79\ -B214330\ -E214520\ -A\ \\\n\t\t>\ t.gill.cal.079\n\n3.\ In\ Splus:\n\nx\ <-\ matrix(scan(\"/data/projects/MICROFRONTS95/raw_data/north/t.gill.cal.079\"),\n\tncol=2,byrow=T)\n\ntime.plot(x\[,1\],x\[,2\],type=\"l\")\n\nplot(x\[,2\],type=\"l\")\nix\ <-\ locator(100)\n\n#\ Select\ with\ mouse\ good\ periods\ on\ each\ side\ of\ the\ calibration\ jumps.\n#\ Click\ the\ middle\ button\ when\ through.\nlx\ <-\ length(ix\$x)\ /\ 2\n\ny\ <-\ rep(0,lx)\nfor(i\ in\ 1:lx)\ y\[i\]\ <-\ mean(x\[round(ix\$x\[(2*i)-1\]):round(ix\$x\[2*i\]),2\])\n\n#\ Look\ at\ the\ jumps\ndiff(y)\nmean(abs(diff(y)))\n\n#\ Compute\ the\ gain\n5\ /\ mean(abs(diff(y)))\ *\ .01\n\n\n5.\ Enter\ this\ gain\ in\ t.10m.N.MICROFRONTS95\n}

The daily plots of relative wind direction suggest that
this error has been around since about day 76 23:00.
I checked the set screws at the direction pivot, they felt tight.
The 3m.S sonic boom was a bit loose where it is inserted into the yoke mount. Tightening the 3 set screws made it more secure. This was done on day 82 at about 17:30

Since the TSI bridge 'appears' to be giving good data in the intercomparison study conducted during the day on (JD 83) Friday, I opted to move the m hotwire to the 3m level and for the rest of the project have a vertical wire (as deployed originally) and a horizontal wire. The 10m platform will remain at that level. However a new mount was fabricated to hold the two hotwires at 3m.

us actually mounted horizontal at 3 meters).
The krypton hygrometer, S/N 1101, arrived from Campbell yesterday. Installed it this morning (15:10 GMT) at 3m.S. Campbell did not do a calibration, but did enclose a note giving the new path length, 1.005 cm. Entered the new path length into prep.config (the old one was 1.300 cm), and restarted covars.
Re-installed t.3m.S at 15:00 GMT. This is the same probe that was removed yesterday, so no cals were done.
On day 84 at 16:25 to 16:30 GMT, Kurt fed calibration voltages from the Fluke dial-a-volt into marigold channel 125 to try to determine the source of the offset on rad.psp.out He stepped through 25 to -25 mV by five mV and one mV from 5 to -5. This data was checked with Splus: slope = 1.0037, intercept = .0113 mV sqrt(mean(residuals^2)) = .037 mV Using a cal of 8.85 microV / (W/m^2) the intercept is about 1 W/m^2, which doesn't explain the 25 W/m^2 offset we see at night.

Nimal requested a comparison test of the two hotwires at 3m.S. The horizontal hotwire on ragwort (now known as 10m.S) was rotated to vertical from 21:48 to 21:54.
Soil samples at 02:20, Day 86: Tare weight Wet Dry -3A 0 29.73 19.59 -3B 0 26.48 17.54 -3C 0 28.26 18.71 -8A 0 29.61 20.75 -8B 0 25.54 17.98 -8C 0 25.20 17.78 -20A -20B -20C These samples were taken near the trailer.
Increased the gain settings for the hotwires. Before the change, the buck and gain settings were: v.3m.S hotwire, NCAR bridge, cosmos 100 flipswitch +5 V Gain knob: 2 Buck adjustment: 4.56 V dv.3m.S derivative, cosmos 101 flipswitch 0V Gain knob: .5 Buck adjustment: 5.28 "v.10m.S" hotwire (actually horizontal 3m.S), TSI bridge, ragwort 100 flipswitch +5V Gain knob: 2 Buck adjustment: 1.93 "dv.10m.S" derivative: flipswitch: 0V Gain: 1 Buck adjustment: 9.75 Note the difference in the gain settings of the derivatives. At 00:50:00 the gain of the 3m.S hotwire was switched to 5. The derivative of the 3m.S has shown problems, with the average jumping to 1 V for several minutes, and then back to 0. It was reading about 1 V during this time. We switched the 3m.S signal to the middle differentiator and saw no change, which indicates the problem is in the buck&gain. When Kurt unlocked the buck adjustment knob on dv.3m.S, the derivative offset jumped down to 0. No adjustment was then made and the lock was not touched again. (suspect intermittent continuity in pot) We'll keep an eye on it. It went haywire on day 85 around the time that Kurt & Bill did the comparison test (though they did not open the electronics shelter). Left dv.3m.S on its original differentiator. Flipped dv.3m.S from a gain of .5 to 1 and back at 00:57:00. Switched the gain of v.10m.S from 2 to 5 at this time.

A C shell script, gravmoist.csh, reads logbook/tklog.log directly and generates output for gravmoist.dat. It creates a three column data file, gravimetric water fraction (%) day 0-3cm 3-8cm Up to this point, the file only contained data for days 58-62 and the gravmoist.dat quantities were expressed as numbers less than 1 and not as percentages. So the soil heat capacity used when computing the surface flux for the daily plot was in error. The Splus functions, soil.params.S and gravmoist.S, were updated to accept multiple columns of soil moisture, and a vector of weights to apply to each column. Currently for MICROFRONTS95, the weights are .5,.5 - ie the simple average of the two samples at 0-3 and 3-8 cm is used when computing the soil heat capacity.
prop.3m.N has suffered some memory loss. After it was

hot wires were reinstalled at the 3m level of the south flux tower at 16:00. the cu/tsi bridge was fine but the ncar bridge decided to be finicky and refused to balance. the probe was OK, and the cable resistance pot (coarse bal.) had no effect. it was determined that the off/bal/operate switch was dirty, no good belly crawling component and i attempted to "field clean" it by rapidly wiping the switch back and forth. after this the probe was balancable, but much to my chagrin, as i barely touched the switch to return it to operate, the balance once again went out. back to the switch with a vengence and low and behold, this time i was successful. the data from cosmos (and ragwort) looked good, so hopefully the bridges will not have to be approached again. back at the trailer, plots of both hot wires were looked at and declared OK. the ncar bridge at the very least needs a good cleaning and possibly a few components. the cu/tsi bridge is no winner either and also needs lots of work to each section of the unit before (if ever) its next deployment.
removed hot wires at 16:37 due to impending showers, will reinstall them when given approval by Bill Blumen.
