• Index

Daily transfer of archive data files to stout is done 
with the /home/aster/scripts/ftp_daily_data. This 
is run from crontab on Charlie's account, since 
batch access to ftp on stout requires an existing account 
there, and aster does not have such an account. 
  
The script is run at 0215 everyday. This is done because 
we are currently archiving on 2 hour segments, and we want 
to make sure that the last file opned yesterday has been closed 
before the transfer starts. 
 
The script yesterday_delete can be run after the transfer 
to delete yesterday's data files. You should check to 
make sure that the data files succesfully appeared on stout, before 
running this script!

ingest bug revisted 
 
Problem seems to be related to the SIGPIPE signal. Found 
that when a socket connection is broken, the ECHILD error 
can be obtained before the SIGPIPE signal is received. After this, 
SIGPIPE is received, and an EPIPE error is received during the next  
fwrite, and clean_up_broken_channel then closes the socket. 
 
In earlier cases, SIGPIPE was not received, and ECHILD 
was encountered continuously on fwrites, since clean_up... 
was not closing the socket. Perhaps clean_up... should close the 
socket on ECHILD as well as EPIPE?

any major effects. Tryed changing rom chips, still no success. At this point, decided to configure 
MARIGOLD to handle fast analog data so Steve O. could check to hot film output. This meant 
changing MARIGOLD's startup.cmd file. The old file is named "startup_old.cmd".

Fixed barometer decode problem, although I'm not sure how. 
 
Barometer message gives pressure in hundreths of millibars, 
so pressures were in the range of 83000. This is larger 
than the 16 bits availible in a short, so had to break 
the decoded message into two shorts, the first with 
the units value and the second with the fractional 
part.

65: INSTRUMENTS , Site none, Tue 18-Sep-1990 20:57:27 GMT, Anemometer Orientations

• Index

From 10 am until 1:30 pm, Gerry Albright and Tom Horst 
used the Nikon theodolite to measure the azimuths of the 
prop-vanes and sonics.  The theodolite was oriented  
with a compass to true north, using a declination of 
13 deg E.  The orientations of the anemometers were 
determined by setting up the theodolite about 150 m 
in front of the anemometer and moving it until the  
line of sight coincided with the anemometer orientation. 
The prop-vane alignments are the orientation of their 
booms, the ATI sonic alignment is that of the u axis,  
and the UW sonic alignment is that of the boom.

ADAM-MARIGOLD: ANALOG SIGNALS 
 
	Today was the day for analog channels in Marigold. 16 analog channels were 
implemented. Below is a table defining those channels. 
 
	A number of problems occurred trying to get the analog system going. 
The first bottleneck was the filter/amplifier backplane for Marigold was not setup 
for the 12 volt supply input. Since the parts to complete the task were not here, Marigold and 
Ragwort hardware were switched. The next problem was one of the cables to connect the 
amplifier/filter board to Datel was bad. A spare cable existed; however, we will need to 
make a new one to complete the analog channels on Cosmos. The final problem was a bad 
12m analog breakout cable. Physical channel 1 on board 2 was bad. The cable will be used since that 
channel is not needed. 
 
	After all the hardware was installed a test was run with known voltage signals thru 
each channel. Everything was acceptable. It was too late in the day to attach the Soviet 
sonic. This will be done tomorrow.

System CRASH when running exabyte. Took a long 
time to get the adams to reboot - problems with 
gmt_tt_set, and datel board. Put debugging 
satements in gmt_tt_set, didn't help. 
Removed taskDelay following spawn of gmt_tt_set,  
and this seemed to solve that problem. Then found that 
Tick_init was initializing SYSTEM_TT from the rtc AFTER gmt_tt_set 
was called, so clock got set wrong. Moved Tick_init before 
spawn(gmt...) in mx320_common_start.cmd 
 
Now, datel was misbehaving. Seemed like the timetags were 
getting trashed. Found that Ticker() was doing a long word 
write to the timetag location on the datel DPR. Matt on 
Friday said explicitly not to do long word writes to the datel 
DPR; that only word writes were legal (can't even do a byte write). 
Datel seems to be working now, but I'm sure other bugs will evolve. 
 
Finally recovered from these disasters at 05:00 gmt, and restarted all.

126: OPERATIONS , Site none, Tue 25-Sep-1990 15:26:58 GMT, cycle archiving for soviet channels

• Index

very interesting: 
 
Last night we disabled the soviet channels in channel config 
and did a data_on to marigold at around 01 GMT. 
 
We left the archiving running. 
 
This means that there was still an open archive file 
for the ussr instrument, although no data was being stored there. 
 
This morning I renabled the soviet channels in channel_config, 
and did a data_on. 
 
I thought that archive would see the later timetags on the soviet data, 
close last night's open file, and reopen a new one. 
 
Not so. archive continued to write to last nights 01 GMT archive file. 
 
What happens is that since the timetags are only in milliseconds 
since 00GMT, archive thinks that if the clock - timetag is  
> 12 hrs., then really the timedifference is 24 - (clock-timetag). 
 
The lesson of the story - stop and restart archiving if you 
are going to stop a channel for a long period of time.

This tape was still going when all arrived ~ 1500 on #270, despite the network 
crash of all of the other archive processes!!!  Furthermore, despite rain just before 
we got to the site (light rain), the probe itself balanced at about 6 ohms, so it 
should still be alive.   
 
Steve S. stopped the tape writing while Steve O. climbed the tower to cover the probe 
and turn off the bridge (good thing too, since it is raining heavier as I write this). 
 
I am now running my exa_scan program, which should tell if there was a large data gap 
during the night.   
 
Note that if things are to be believed, there should be about 6 hours of data on file 1 
and another 12 hours on file 2 - 18 hours of data on one tape isn't too shabby!

ATI (13m) 20 
Psychrometers: 14-17 
Obviously, the absolutes are off and will have to be changed later on. 
 
With the cover tube on, all temperatures raised by about 10 C, taking about 
2 minutes to stabilize.  It would appear that the tube attained near body temperature 
while being carried in my brest pocket up the mast, and that the incident solar 
radiation was enough to prevent it from cooling significantly.  This is more than 
I would have expected.  
- 
Even with the tube on, fluctuations appeared to be about +/- 10 mv on the DMM 
(read by Michael).  Within this error, all of the sensors appeared to have correct 
gain settings to cause a change of 0.5 V in "cal" mode.  If it is necessary to  
get better accuracy, look at the data file collected during this period.  (The 
above listing is the order in which the calibrations were done.)  I held each 
sensor in cal mode for about 10 seconds (expect the first - UW 4m, but I think 
there is still enough data there).  Since all bridges appeared to give the 0.5 V 
change, NO ADJUSTMENTS WERE MADE.

	Favorable winds called for

data at 16:20 GMT. There were no problems 
getting the instrument running. I would 
recommend after turning everything on and 
confirming things are working ok in the base 
that the bridge adjustment be reset. This 
way the electronics has a chance to stablize. 
 
	I was not successful in running 
Steve's 'ql.sh' routine to verify data on tape. 
The program would boom out with a 
"log10: SING error" followed by a 
"ERROR  5 in AGNUMB - EXPONENT TOO LARGE". 
I went ahead and started recording on tape 
anyway. 
 
	When starting a new tape, the first 
7 or 8 messages from daisy seem to get 
written to tape; ie; the light blinks. 
After that there is a 10 to 15 second delay 
before things start going again. I assume 
it has something to do with the exabyte 
wanting to put a header file at the 
beginning of tape. Maybe this is why S.O.'s 
program failed. I'll talk to Charlie about 
it.

• Index

Ati sonic cabling problem was discovered and fixed 
yesterday. Cross-talk was occurring between the ATI 
sonics because the caables were strung too closely 
together through the tower. After re-wiring the sonic 
cables to maximize seperation, the cross-talk  
disappeared. The problem manifested itself as a 
burst of spikes building up to peak velocities 
above 10m/s, lasting for approximately 20s, with 
a period initially of 3min 13s. Later secondary 
bursts occurred at different frequencies. These 
periods were the beat frequencies between the 
various sonics. Ski asked Herb about it. Herb's 
reply was that all sonic cables must be seperated by 
a minimum of 4 in to eliminate the problem.

4m.u we also put on zero wind box and manually reset 
the zero level on the pot. However, there was 
about a 5m/s wind at the time. No zeroing was done  
on the ASTER computer. Ski says the 4m.u board is 
noisy, aand may quickly give us spikes again if 
the winds are stronger. 13m.w had a lot of noise before 
thresholding,  and an apparent bias. Now only a bias 
is obvious. Tom suggests that if the winds are light 
tomorrow that we put the zero box  on all of the 
rethresholded paths and record the bias levels 
using xstrip.

• Index

Proceedure for soil moisture determination. 
 
Soil samples are to be taken for soil moisture determinations. 
The area from which the samples are to be obtained is off to the side 
of the dirt path in the vicinity of the transformer. 
 
Samples taken in the field should be representative and should 
fill one of the large foam cups provided. 
 
The 0-3 cm sample should be obtained using a spoon. Approximately 
four samples from the furrow and four from the ridge will fill the cup. 
 
The 3-10 cm sample should be obtained using the soil corer. The corer should 
be pushed into the ground to a depth of 10 cm and withdrawn. The first 3 cm 
is to be discarded and the rest of the core scraped into the cup. Four or five 
cores will be needed. 
 
The 10-30 cm sample should be obtained by digging a pit 30 cm deep. After 
cleaning the wall of the pit the spoon may be used to score the side of 
the pit between 10 and 30 cm to obtain a good sample. 
 
The samples should be brought back to the base and each sample homogenized. 
Vegetative material and pebbles are to be removed and lumps crushed. 
Triplicate aliquots of each sample, weighing approximately 25 g, should be  
loaded into Al weighing dishes which were previously mmarked on their bottoms. 
 
The dishes should be arranged on the oven tray and the tray inserted 
into the oven. 
After heating the sample at 110 centigrade overnight the tray should be 
withdrawn and the samples allowed to cool. They should then be weighed to an 
accuracy of 0.1g.

• Index

Proceedural failure which caused data loss. 
 
During the previous evening tape backup proceedure 
the disc file were not erased. 
This lead to the disc capacity being exceeded at 08:00. 
On arrival at 08:30 we attempted to erase the offending files but instead 
suceeded merely in erasing the fast data from the recent night. 
 
The problem was that we ran the script "bkfiles_kill", which detects the 
time when it is run.  We intended for it to kill yesterday's files, but it 
recognized that it was morning and deleted the morning's files. 
(Since the disk filled up at about 0500, this resulted in the loss of only 
5 hours of data - the disk filling up caused another 7 hours to be lost). 
 
The mid-day data from day 281 hadn't been stored also, since no one was at 
the site the evening of day 281.  The data from day 281 and the little bit 
of data from 1200-1400 of day 283 were appended to the tape which only had 
the fast early-day day 281 files on it.  Since the day 282 files had all been 
archived yesterday evening, they were simply deleted. 
 
Finally, when the disk space became available, archiving was still going on 
the day 283, 14:00 files, so there will be a data gap in them.

but it is running at about 4 ohms, rather than the balance point of about  
7.4.  This will have to be worked on further. 
 
Steve was at the masts from about 1300-1600 local working on this and 
the sonics.  Also about 1100-1200 earlier.

Prop reconfiguration 
 
Because the prop which was at 7m (W004) has been acting up (and because 
I broke it's propeller), it has been moved to 1m.  The prop which was at 
1m (W001?) has been moved up to 7m.  
 
In addition, it was found that the bearings on W003 (4m) are rough and 
may have contributed to the speed drop-outs.  The spare prop (W007?) will 
be put in its place.  Thus, in a few minutes the arrangement should be: 
15 m  W006 
10 m  W005 
 7 m  W001 
 4 m  W007 
 2 m  W002 
 1 m  W004 
 
Since the alignment of the 1 m and 7 m booms differed by only 30 seconds 
of arc according to the theodolite measurements, the direction was not 
reset for W001.   
 
W007 will be programmed with W003's pitch and direction.

The hot-wire wouldn't balance, but the probe was good.  It turned out that the cable capacitance 
was off enough to cause the bridge to oscillate again.  I reset everything AGAIN using the 
square wave test, this time following Carl's instructions to be satisfied with positive and 
negative excursions (not a square wave, more like a square wave differentiated), and to allow 
a few overshoots.  The bridge still looked like it was generating about 10 mv pp of white noise, 
which was reduced by the low-pass filter, still set at 5 KHz. 
 
Tape was started, but will be stopped to do quick_look and restarted now.

Playing around with v.ati.7m triggering 
 
The received wave on VR2 (on the top of the board) is having trouble.  There are a weak 
positive-going, a rather strong negative-going, and a strong positive-going half cycles. 
Currently, it is triggering on the strong +, and appears to have a wind speed bias of  
20 m/s.  The best point appears to be the strong -, but the sonic would have to be rezeroed, 
and the wind speed is now strong enough (6 m/s) to make that difficult).  I will now reset  
it to the weak + and hope the signal improves. 
 
The signal got better, but didn't appear to be a function of triggering.  Probably, 
triggering on the strong + was best, since the wind values appear to be a bit low. 
The winds are too strong to be able to detect the change of one wave ~= 1 m/s.  Zero  
should be checked the next time winds die down.

After zeroing 13m.ati, the w component improved

result of a true zero bias offset (we put the  
zero wind box on the w-axis twice and got the 
identically same offset value of 0.27 m/s, so we  
our correction was right) the conclusion is that 
it must be coming from somewhere else. Could 
the sonic have a big enough tilt to give this 
big of an offset? Seems unlikely.

Channel reconfigurations, etc. 
 
Today we did a lot of channel swapping to try to read the new PAM barometer board.  Here goes 
a memory dump (from me): 
 
~1220 local:  NOAA sonic taken out of marigold:206 and replaced by the new PAM barometer. 
~1230 :       marigold crashed because of data coming in at an unexpected baud rate - restarted 
              and reconfigured for the new baud rate. 
~1250 :       new PAM board temporarily put in old PAM channel (marigold:203) for testing and 
              soon swapped back. 
 
~0035 :       Psychrometer at 15m rewired back to RAGWORT:202 (formerly Wim's IR sensor) 
              NOAA sonic wired back to marigold:206 
              new PAM barometer put in marigold:207 (old psychrometer@15m channel) 
 
This means that analyzing data from today will be tough.  (The winds (direction) were bad  
until about 2100 GMT anyway.)  Also, the files: psyc.15m are no longer being created since 
the data are now stored with the other psyc channels. 
 
The new PAM barometer data are being stored as: pam_new.bar.  Note that the files which 
were just archived to tape have channel id #206, whereas the pam_new.bar files from now 
on will have channel id#207. 
 
Sorry 'bout all this, but we should now be in a better configuration.

New configuration on marigold 
 
The second new PAM barometer board has just been added to marigold. 
The status is: 
marigold 206 - new board #0001, 2 ports plumbed to 4m (in parallel with 
               the old PAM board), other port plumbed to 7m (also in 
               parallel with the old 7m PAM board). 
marigold 207 - new board #0002, all three ports plumbed to 13m (in  
               parallel with the old PAM board at 13m) 
 
Note that this required changes in archive_config, channel_config, 
preprocess_config, and did.config.  The new versions of these were created 
in /ops4, and pointers in /config set to point to them.  Archiving was 
shut down and restarted just before this logbook entry was started. 
 
Also note that the NOAA sonic is no longer connected (or archiving).

See entry #472 for most details.  Here I wanted to mention that the tubing going 
down from the 7m port to the transducer at 4m was wrapped around one leg of the mast, 
so it should be relatively vibration-free.  Also, I am not sure which of the ports 
is which (and therefore which one is 7m).  The 7m port is connected to the transducer 
closest to the edge of the board. I'll look at the data to see which one this appears 
to be.

I won't bother to get it going until after the archiving since winds are still southerly.

Psychrometer wick changed 
 
Since the wet at 10m was reading like a dry, we just: 
- dropped the psyc tower, put new psychrometer@10m in, raised tower 
- found that the new one still read low (about .2C), but was wicking okay. 
- dropped the tower again, put back the psych. which was there 
- tested on the ground, found that the wet was still dry 
- traced problem to the wick - water was beading  up on it 
- replaced wick with the wick in the new unit we had just put up. 
- tested - seemed okay 
- raised tower 
 
Note that before raising the second time, ragwort crashed (perhaps because 
Tony was walking on the walkway nearby?).  I will make another entry in  
operations about this.

rawort crashed ~1757 
 
While working on the psyc. tower, rawort crashed.  The only causes I can 
think of are: 
- a bad message from the psychrometer just installed (unlikely, since it 
  had been running for about 2 minutes and reading okay on "temps"). 
- the e`net cable may have been stepped on under the walkways. 
 
I had noticed a fair number (3?) of time_tag errors/sample dropped messages 
on the ragwort console before the crash.  I believe that the error message 
of the crash was a broken socket. 
 
I rebooted ragwort by rlogging-in from cosmos and mxresetting.  I started 
archiving, but then started the wrong sonic spike tester, and in the process 
of killing it, killed the archiving instead.  Eventually, I got both (plus 
covar) running again, but there will be a very short (~2 min) set of archive  
files from this mistake.

This is late since I was looking at the signal in detail.  It turned out 
that the bridge was unstable, and cable capacitance had to be changed. 
This was causing a lot of extra noise on the hotwire signal.  (The noise 
level was relatively low, so it didn't appear until the quiet stable 
conditions tonight.)   
 
I had also tried connecting the wire directly to the differentiator 
(on both channels, the diff. bypassed on the Eb signal), to avoid 
having the buck&gain.  This didn't help the signal at all, so it is 
back.  I also resoldered all of the connections on the other bridge (#2) 
and will try using it again tomorrow.

marigold crashed when xstrip backed-up 
 
While doing sonic zero checking on ati.7m, xstrip hung up.  The first time 
on cocklebur, there was VERY sluggish mouse response.  The second time on 
aster, the display suddenly hung, with no more information.  The only way 
either were stopped was by using "destroy window".  In the meantime, while 
I was figuring this out, marigold crashed, probably because of data backing 
up.  I`ve just restarted marigold again with its associated tasks.  Strange.

• Index

Sonic zero tests: 
 
These are all pretty rough - there were typically LOTS of spikes with the zero  
chamber on and xstrip/marigold had problems in the middle of everything. 
Nevertheless, here they are: 
 
	   U	 V	W 
ATI.13  -.2   -.1    -.42 
ATI.7   -.03  -1.0   +.00 
ATI.4  -1.15  +.08   +.23 
 
None were done on the UW sonic, since xstrip now displays u,v,w 
instead of a,b,c.  Next time, we'll use rserial instead on 
these channels. 
 
P.S. These values are consistant with the values from graph_mean 
today.  Note that since the value of +1.0 for ATI.7.V was obtained from 
rserial it was negated as per the calibration routine.

hotwire rebalanced about 10 min. ago (~01:40) 
 
Since hot_spec showed a lot of noise, it was necessary to change something. 
The bridge had wanted to balance at about 4 ohms this afternoon (~0130 local) 
so I changed it.  Just now, I've changed it back to about 7 and the noise 
went away (or at least diminished in amplitude).  This means that the  
last 5 hours of data may be bad.  (But mostly bad directions anyway.)

I saw a message to the effect of: 
"9137 retries on tape, tape either worn out or drive needs

We used one of the cleaning kits, which seemed to work properly 
(ejected after about 15 seconds).  Note that the kit says that 
it should be used every month or 30 Gigabytes (12 full tapes), 
whichever comes first.  Probably once a week up here would be 
a good idea.  I had noticed that there were about 3000 retries 
as of yesterday or the day before.

The north beam was completely dead, and has been

by the high mode. The profilers were also releveled. It 
appears that they were pretty far from level as the

• Index

NEW GRAPH ROUTINES 
 
	All the scripts for the standard graph routines 
are in /home/aster/scripts/graphs. Links have been made 
so these routines should execute from anywhere. 
These routines use the preprocess data files which reside 
in the appropriate directories. As an example, data files 
for prop or psyc reside in: 
	 /home/aster/projects/FLAT90/results/profiles/auto. 
 
The routine graph_wind does a batch call to Splus to graph 
the wind data. It will not output the graph to screen but directly 
it to the printer. This takes about 30 seconds. You can still 
use the interactive call to Splus to generate graphs. The only 
difference is the parameter passed in function fun.winds should 
make access to the subdirectory auto; ie; fun.winds("auto/prop#307"). 
The new version allows you to select which sensor you wish to plot. 
The calling procedure is: graph_wind  . The sensor 
ID is the height of the desired sensor. 
 
	In directory /home/aster/scripts/autoproc are the routines 
to autoprocess data in background. The main routine autoprocess.bat is 
called,using the crontab file, 15 minutes pass the present hour. 
Processed data is appended to the appropriate file (refer to comment 
above about location of data files).  
	The file autoprocess.file is necessary and must not be destroyed. 
autoprocess.bat uses it to determine the last files processed and which 
files are next. 
	The file autoprocess.init can be used to recreate the autoprocess.file. 
It will setup the autoprocess.file to process all rawdata from hour 00 to the 
last closed file. It will destory any processed file for the present day. 
Once this is done, the first process run of autoprocess.bat will create a 
processed file from hour 00 upto the last closed file. 
NOTE: this has not been completely tested!!!!!

Replaced fast t probes on ati tower 
from 21:35 to 22:15.  Covered each 
and read output from cshow in both 
calibrate and operate modes.  From  
8-10 samples, the gains are: 
 
13 m ATI:  5.03 +/- .02 
 7 m ATI:  4.86 +/- .005 
 4 m ATI:  4.66 +/- .02 
 
Note that the previous calibrations  
similarly increased with height. 
This will account to some degree 
for the `observed' increase of  
heat flux with height.

• Index

Read sonic zero winds with rserial, 
finishing at 19:20.  Charlie recorded 
samples of the output from rserial 
and placed them in the files  
results/ati/sat1.u, etc. and 
results/uw/suw1.a, etc. 
 
I plotted histograms of each sample with Splus. 
Most of the ati sonics had multiple modes with 
a spacing of 11-12 counts.  This indicates  
mistriggering with various numbers of false 
counts included in the 10 sample averages output 
by the sonic. 
 
Some of the ati channels may be okay.  The resulting 
means were: 
 
sat1.v:   -9.5 +/- 1.4 counts  (55 samples minus 8 > 0 counts) 
sat2.u:  -16.5 +/- 1.8 counts  (55 samples minus 2 @-5 counts) 
sat2.w:    0.2 +/- 0.5 counts  (55 samples) 
sat3.u:   -0.5 +/- 1.0 counts  (55 samples minus 4 > 5 counts) 
 
The uw sonics did not appear to have this problem. 
The resulting means were: 
 
suw1.a: -109.5 +/- 3.8 counts  (54 samples) 
suw1.b:  -16.7 +/- 3.9 counts  (54 samples) 
suw1.c:   12.7 +/- 3.0 counts  (54 samples) 
suw2.a:  207.1 +/- 3.1 counts  (45 samples) 
suw2.b: -151.3 +/- 2.9 counts  (45 samples) 
suw2.c:  160.3 +/- 3.2 counts  (37 samples) 
 
In all of the preceeding cases, the median values were within 
less than 1 count of the mean.

	Two more analog channels were added to the

cosmos 112, pyg.in.raw. The gain setting for the 
ozone sensor is 1 with a 1 hz sampling rate (the filter 
is a 10 hz filter from GILL days). Pyg.in.raw has a  
gain of 200 with a .5 hz filter. The calibration settings 
in preprocess are as follows: 
			      ozone: .0001525925 (volts) 
			 pyg.in.raw: .0007629625 (mvolts) 
 
The analog cable for channels 108 to 111 on marigold was moved 
to the radiation saw-horse to get channel 112 going. 
This work took place between ~21:00 and 23:00 GMT out at the array.

Attempt to solve the difficulty with xstrip lethargy 
 
The xstrip process was becoming very slow. To solve we undertook to: 
 kill the archiving process on marigold and then sequentially brought it back 
 This did not improve matters. 
 kill the cov_ati and the sonic spiker on marigold and then bring them back 
 We could not bring back the spiker but decided that it was not important. 
 
None of these activities did any good and the xstrip is even slower. 
Every thing except the spiker is operating so we have left the problem 
for consultation with Steve S or Charlie.

639: BAROMETERS , Site none, Fri 16-Nov-1990 19:51:49 GMT, Al was here!

• Index

Al was here!   
 
First test (~10:00 local) was to insert resisters (a dummy load) into Al's box at 4m - 
  this added about 480 microbars to the signal and had noise on the order 
  of 10^-9 (in power), which looked white. 
 
Next test (~10:30 local) was to insert dummy loads into the boxes at 7m and 13m.  Both 
  of these threw the balance offscale (<-5V), so Steve S. changed the jumpers on the  
  filter board to make a gain of 1/2 about 10 min. after the loads were inserted. 
  It was obvious from this test that the 4m had more noise, which looked like aliasing 
  of a high (>10 Hz) signal. 
   
Final test (~12:30 - after Al left) was to move the analog cable from the 4m box away 
  from all other cabling (including power).  The noise on the 4m signal is now much 
  less than the one at 7m.  WE SHOULD HAVE DONE THIS TEST LONG AGO!!!  Al thinks that 
  the noise is still low enough that it won't effect unstable data (or even stable 
  data in moderate (>3 m/s) winds), but it would have been nice.  Oh well...

~1200 (local) Calibrations were done, with files captured from cshow.  Each file has

  probes were removed.  The order of these tests was: 
  ATI 13, ATI 7, ATI 4, UW 7, UW 4. 
 
Resistances were measured in the trailer shortly after for each of the probes.  They were: 
ATI 13 - 149.2 
ATI 7 - 150.5 
ATI 4 - 144.2 
UW 7 - 147.7 
UW 4 - 149.2
