| Graphic: | TRH cal check
Please enter this record of the laboratory recalibration of S/N 502 in
the CHATS logbook:
S/N 502 was originally at the 6 m level on the vertical tower and was
replaced with S/N 206 on March 21 (entry 31). Ned and I had detected
the -0.3 deg C error in the profile plots. We will send it out to
replace the TRH currently at 6 m (S/N 101) which we removed from the
horizontal array (entry 93) because it appears to be in error by -0.1
deg C. Send S/N 101 back for laboratory recalibration.
Thanks,
Tom

Here is the result of the temperature check on TRH502. It had a mean
error of -.3133 C (sensor - ref). If we want we could use this as a
correction to the data when this sensor was deployed. New coefficients
will be computed.

Recent work:
Yesterday--
- Cleaned all optical sensors (except 16m rad)
- Reconfigured to low/wide array
- Reinstalled all hotfilms
- Filled water tube for p' sensors
Today--
- Measured north tower and horizontal array cable tensions.
- LAI measurements
- Gravimetric and TRIME soil measurements
- Trouble shooted North Tower ethernet problem.
- Trouble shooted Oncley pressure sensor [fixed by 12:30].
To Do: Measure new sonic heights and azimuths
(better done at lower height)
Measure tree diameters for Pete
Fix network problem with hftower
Clean radiometers at 16m
Summary:
After getting 43 hours in mid-level/wide configuration, we moved to the low-level/wide configuration.
(We had to the array to install the hot-films anyway.) We also cleaned all sensors (which had
a lot of pollen accumulation, but no noticable herbicide spray).
hftower still has some problems, but hopefully a workaround is imminate. Also I've been working
on p' tests today.

125: rad_soil, Site 30m tower, Mon 09-Apr-2007 08:22:43 PDT, soil samples
I've set up the corer to take 0-3 and 3-6cm cores. I'm processing the entire
3cm-thick core as one "aloquot". I've been turning the oven off between
samples.
4/9:
This should be considered close to the driest case. The soil crumbled out of
the corer on my first try. I undercut the corer with the trowel and tilted
it out of the hole to recover the final core. Nevertheless, the clay-like
clumps do have some internal adhesion.
I got "bad TDR level" on the TRIME when using the normal probe at 1 location.
I then tried the removable probe and got a reading of 17.4-18.0%.
I then moved the removable to another site and got the 23.4% noted below.
Thus, I'm worried about the soil salinity -- we'll have to watch it.
NOTE!!! I left the removable probes in the 23.4 location. Future readings
should use these. They are about 2m to the South and slightly West of the
fixed soil probe stake (with the orange flagging).
4/12:
Slightly moister upper layer after 1mm of rain. Still a lot of variability
in TRIME readings, even using prongs that have had a lot of time to settle.
Actual readings were: 24.1, 25.0, 26.1, 24.7.
Some of the core dirt pushed out of 0-3 and also there was some spillage.
Thus 0-3 probably is 0-3.6, 3-6 is 3.6-6.6cm. I wouldn't use this 0-3 for
density.
4/15:
Morning after irrigation AND rain, so probably the wettest it is going to get!
0-3 was not quite deep enough, so don't know about bulk density.
TRIME was reasonably consistent: 34.4, 34.6, 34.7.

124: communications, Site 30m tower, Sun 08-Apr-2007 18:47:12 PDT, power cycled hub in lower
We lost communications to the 30m tower this afternoon. After trying lots of
things (and it not being quite as high a priority as all the other stuff that
Keith just discussed), I just cycled power on the hub, which appears to have
gotten things working. Unfortunately, we still have the 16% packet dropouts
which is causing Gordon to be unable to update the hotfilm acquisition code.
Thus, the triple-film probes probably still have the channel shift problem
but the singles on hfarray should now be running his new code.
123: licor, Site horizontal array, Sun 08-Apr-2007 18:31:08 PDT, Horizontal Array Licor Sensors Cleaned
The licor sensors on the hotizontal array where cleaned today after the Saturday morning tree spraying.
122: kh2o, Site horizontal array, Sun 08-Apr-2007 18:29:56 PDT, Horizontal KH2O Sensors Cleaned
All of the horizontal array KH2O sensors where cleaned today after thr Saturday morning tree spraying. Distilled water and QTips where used to clean them.
121: hot films, Site horizontal array, Sun 08-Apr-2007 18:28:42 PDT, Single Hot Films Reinstalled
The single hot films for the east, west, and center sections where reinstalled after the saturday tree spraying.
120: logistics, Site horizontal array, Sun 08-Apr-2007 18:25:54 PDT, Horizontal Array Lowered to Lowest Level
The east and west sections of the horizontal array where lowered to their
lowest level. The center tower sonics, TRHs, and data boxes were also lowered.
Started lowering west ~14:30. Finished up ~17:25.
119: rad_soil, Site 30m tower, Sun 08-Apr-2007 18:24:07 PDT, Radiometer Cleaned
The radiometers just west of the 30 meter tower where cleaned today after the Saturday morning tree spraying.
118: pressure, Site 30m tower, Sun 08-Apr-2007 18:22:16 PDT, 11m pressure sensor tube on 30m Tower Filled
The 11 meter pressure sensor tube on the 30 meter tower was filled with water. No leaks where detected.
Also added one more cable tie to the copper tubing at the top to lessen
vibration of the tube.
Also Tee-d off Steve's Paro with Bill's xducer and connected the Paro to
lower's ttyS9, but still not getting data.
117: data system, Site 30m tower, Sun 08-Apr-2007 18:17:41 PDT, Power Board on Viper Data System Replaced
While examining the inside of the Viper Data System on the 30 meter tower, I noticed that the connector on the power board of the PC104 stack had a broken solder connection. The power board from the spare PC104 stack was used to replace it.
116: kh2o, Site 30m tower, Sun 08-Apr-2007 18:16:16 PDT, KH2O Sensors on the 30m Tower Cleaned
All KH2O sensors where cleaned on the 30 meter tower after the Saturday morning spraying of the trees. Distilled water and QTips where used to clean them.
115: hot films, Site 30m tower, Sun 08-Apr-2007 18:12:49 PDT, Reinstalled Triple Hot Film Elements
After the tree spraying Saturday morning, the triple wire Hot Films where reinstalled on the 30 meter tower starting the lowest and working upward.
P.S.
I this was the time when we installed the new data acquistion code via
the spare Pocketec to avoid the channel slip problem.

We will move to the low-level array since we have to lower the array for hot-film
access anyway today.
We still have network issues with hftower, data dropout/skip problems with both
hot-film dsms, p' calibration issues, and p' noise issues to solve.

113: software, Site all, Sat 07-Apr-2007 17:42:51 PDT, finally configured ops5!
I finally got around to making this configuration ops5. I've renamed the
configs simply high.xml, mid.xml, and low.xml, referring to the heights of
the horizontal array and config.xml simply points to them in turn.
I've assumed that the times that specify the ops periods are in GMT.
112: logistics, Site all, Sat 07-Apr-2007 16:54:13 PDT, spraying schedule
According to Antonio, spraying was delayed due to staff schedules and didn't
end up starting until 5AM this morning. Our towers probably were sprayed from
6-7AM. They have continued spraying today (despite marginally high winds),
but will stop for an Easter break tomorrow before finishing the field. They
probably will need to spray Monday as well.
Thus, we should be able to reenter the field tomorrow late morning via the
long way around the perimeter of the field. We won't be able to take the short
cut through the trees until at least Tuesday.
111: pressure, Site 30m tower, Sat 07-Apr-2007 16:51:28 PDT, config mods for upper
In an attempt to determine why the p' signal has a peak at 4Hz, we ran upper
with a base sampling rate of 400 (rather than 200) sps during the period
~15:58-16:45. Everything should be back to normal now, but upper has been
restarted several times.

Fix network problem with hftower
Summary:
Horizontal array at mid-level, wide. 31 hrs of good data in present configuration.
We have confirmed problems with the hotfilm data acquisition systems intermittently loosing data
and scrambling the channel order. We have a plan for a workaround, but Gordon may come up with
a real fix. The network is also down to hftower, but we are not losing data since no probes are
installed.
There were some data issues associated with adding the p' sensor (which is the first time our
new data systems are acquiring "standard" analog data), but these now appear to be resolved.

109: communications, Site 30m tower, Sat 07-Apr-2007 11:19:40 PDT, hftower network problem
Yesterday afternoon we started having network problems with hftower and it is
now mostly down. I reseated many of the cables at about 1730 yesterday but
found no obvious problems. Next steps would be swapping cables between
hftower and upper and checking the cable itself going up the tower from
lower [with the hub] and hftower. These will have to wait until tomorrow
when we can reenter the field. Since hotfilms are all down, we aren't losing
data in the meantime.
108: logistics, Site all, Sat 07-Apr-2007 11:03:10 PDT, AC power out to array?
Yesterday Antonio asked if he could turn off AC power to the towers while
he was digging to replace sprinkler lines near our buried cable. Since all
of our sensors are connected to batteries, this was fine. We don't know if
he actually disconnected, but we didn't notice any adverse affects.
107: hot films, Site all, Sat 07-Apr-2007 10:52:59 PDT, hotfilms removed
To avoid damage from the spraying last night, we removed all hotfilms yesterday
afternoon.
~1430-1500 removed triple probes from 30m tower in the order bottom to top.
~1530-1700 removed single probes from horiz. array in the order west to east.
Gordon may have been playing with the adams hftower and hfarray during this
time, so the data during these removals may not have been recorded.
We also bagged some of the stuff on the ground and turned the guywire lights on.
Don and I drove by at night and confirmed that the lights are quite visible.
We also pulled the Pocketecs out of hftower and hfarray about 1800. These have
now been copied to the trailer USB disks.
106: pressure, Site 30m tower, Sat 07-Apr-2007 09:48:18 PDT, p' tests
Gordon got the A/D code running early yesterday afternoon. The main fix was
to change the Diamond A/D card to interrupt #7.
By that time, we
also had added a fuse to get Bill's transducer going. Bill and I checked
whether his transducer gain was 25 mV/ub (as per the factory/Bedard spec) or
18.6 mV/ub (as per my test in the wind tunnel last month). We lifted the
box several times by 1.5m, between ~15:05-15:18. I'll be looking at the
data soon, but our impression using the DVM was that 18.6 probably was correct.
dp = rho g H; rho~1.23, g~9.81, H~1.5 => 18Pa = 1.8ub => 45mV@25 mV/ub or
33mV@18.6 mV/ub. Our impression was that we were seeing closer to 33mV steps.
[Also, I need to calculate rho for the exact conditions at this time.]

needing to fill the pipe.
Don and I go to Davis today to fill my reservoir with N2, which I need to do
before deploying my transducer.
We expect Gordon to load the software to drive the A/D board later this morning.

Apparently, upper didn't restart correctly when I did the A/D board install
this morning. All the Emerald channels (everything above 9m) were not being
recorded. I restarted with an "adn" and "aup" and everything now appears
normal. This may have been due to the GPS hanging when I powered up the
system (which was due to the lid of the box covering the GPS receiver when
it was open!). I finally fixed the lid problem, but apparently the system
wasn't happy.
I'm sorry!!

[Tom wrote this this morning, but I'm only getting to inserting it into
logbook this evening. Some actions have been done by now -- see entries
from earlier today....Steve]
On Site: Romberg, Oncley, Lenschow, Horst left this morning
Recent work:
Don finished raking the power line ditch.
We moved the horizontal array down to 5.5 m.
To Do: Measure new sonic heights and azimuths
(better done at lower height)
Take gravimetric soil moisture samples
Remove hot films and turn on lights prior to spraying schedules
for Friday night
Measure tree diameters for Pete
Replace broken hot film
Install p' sensors
Summary: The hot film on sonic 5t is not working. Presumably we broke it
when we removed it and put it back in place to move the sonic.

101: whatever, Site 30m tower, Thu 05-Apr-2007 17:00:55 PDT, tower climbing
To begin the p' sensor install, I climbed at various times between 1445-1645.
The 11m sonic was tilted up from ~1445-1530.
100: hot films, Site horizontal array, Thu 05-Apr-2007 12:08:59 PDT, Replaced central hotfilm
The probe we removed from the central tower yesterday (SF6) did appear to be
broken when I poked at it this morning. Tom is taking it to Boulder to be
sent for repair.
We installed a new probe (SF2) at about 1140, but had the wrong DIP switch
settings. Settings were corrected 1239 and the signal looks okay.
**** WARNING ****
The probe appeared to be slightly rotated, so I reoriented it more vertically.
I estimate that it was rotated ~5 degrees, with the bottom more Easterly than
the top. I realize that the calibration procedure may have to be altered.
P.S. 4/10/07:
Under microscope inspection of SF6, Greg and SteveS found a minute separation
between one end of the hot film and its support.
99: hot films, Site horizontal array, Thu 05-Apr-2007 12:05:18 PDT, hfarray channel test
~1147: tested hotfilm channels by shorting each input sequentially for 10s each.
The order was: (frontpanel input channel) 0,1,2,3,4.
I'll look at the data to see if this ended up being correct.
Note that the central hotfilm (ch 2) was reporting (incorrect, but fluctuating)
voltages at about 2V.
[THE RESULTS!!! (in GMT, using:
data_dump -d 6 -s 11 -p hfarray_20070405_183000.dat | more)]
This file just happened to have a data dropout example, that shifted the
data from being reported correctly (broken hotfilm voltage of 2.6V was on
[0-based] ch2), to being shifted by 2 columns.
The shorts of frontpanel inputs 0,1,2,3,4 appeared in data columns 3,4,0,1,2
(during the period 18:48:37-18:50:18). Note that the shorts appear as "nan"
and that disconnected inputs float to >3V.
-- loss of data. Note the negative deltaT! --

Here is a sample data dump from hfarray. It appears that the last channel
may be bad. It is highter than the rest and more constant with time.
[After talking with Gordon, this Viper was rebooted ~1000?? and the channel
order changed! Now that we've replaced the probe, it isn't easy to dump these
data.]

Recent work:
Yesterday we diagnosed the temperature error on the horizontal array
and swapped the upper TRH with the 6 m TRH from the vertical tower.
The upper TRH, now at 6 m, appears to be low by 0.1 deg C.
To Do: Measure new sonic heights and azimuths
(better done at lower height)
Measure LAI
Take gravimetric soil moisture samples
Remove hot films and turn on lights prior to spraying schedules
for Friday night
Measure tree diameters for Pete
Summary: Data generally look ok; so far we have 47 hours, 55 minutes of

93: trh, Site horizontal array, Tue 03-Apr-2007 10:53:02 PDT, horizontal array TRH's
Don and I compared the horizontal array TRH's to those on the vertical tower
in an attempt to determine which of the two might be out of calibration.
The results were somewhat inconclusive, but with a tendency for the TRH at
the greater height to perhaps be reading too low.
Perhaps a more definitive answer could be obtained by first filtering the
data by wind direction.
This afternoon, we swapped the 6 m TRH (s/n 206) with the top (10.6 m)
TRH (s/n 101) on the horizontal array:
14:00 removed 6 m TRH
14:15 mounted in at 10.6 m on horizontal array
14:35 mounted 10.6 m TRH from horizontal array at 6 m
Don and I concluded that S/N 206 is reading 0.1 degree too low
Removed 10.6 m TRH (101) from the vertical tower at 16:03.
Removed 9.6 m TRH (704) from the horizontal array at 16:11
Moved 6 m TRH (206) to 9.6 m on horizontal array at 16:16
Reinstalled 10.6 m TRH (101) at 10.6 m at 16:18
Installed 9.6m TRH (704) at 6 m on vertical tower at 16:23
The 9.6m TRH looks okay, so swapped sonics back to previous
configuration:
Removed 9.6 m (704) from vertical tower at 17:30
Required some repair of joint between aspirator and electronics
Removed 10.6 m (101) from horizontal array at 17:35
Lost track of time
Moved 6 m (206) up to 10.6 m
Mounted 9.6 m (704) back at 9.6 m
Mounted 10.6 m (101) at 6 m on vertical tower
Finished at 18:05
Final configuration:
6 m on vertical tower = original 10.6 m on horizontal array (101)
which is ~0.1 degree too low.
9.6 m on horizontal array is original (704)
10.6 m on horizontal array came from 6 m on vertical tower (206)
92: sonic, Site horizontal array, Tue 03-Apr-2007 09:25:51 PDT, Sonic 3t stopped at 10:10, April 2

Sonic stopped at 10:10 on April 2, which was around the time that Keith was
cleaning up the cable tangle that resulted from the reconfiguration of the
array. From the sonic "diag" it appears that Keith did this work from
~9:00 - 10:30 April 2.

First we lowered the array to near ground level for easy access, then we
spread out the sonics, and then we raised it up to the former height at the top
of the canopy. This was begun around 10-11 AM and completed at 8 PM.

74: whatever, Site 30m tower, Fri 30-Mar-2007 15:14:57 PDT, Heights of scintillometer and particle counter
Jan Kleissl plans to install his scintillometer on the 30 m tower. We
are measuring 4-component radiation at a height of 16 m, so we would
like to minimize the influence of the scintillometer as much as
possible. The influence of scintillometer on the radiation measurements
will decrease with the cosine of the angle from the zenith at which
the instrument is seen by the radiometers and with the square of the distance
between the scintillometer and the radiometers.
Let z be the height difference between the radiometers and the
scintillometer and x be the horizontal spacing between them, roughly the
length of the radiometer boom. Then the cosine of the viewing angle is
z/sqrt(x^2 + z^2) and the distance between them is sqrt(x^2 + z^2).
The relative influence at different mounting heights is then
z/(x^2+z^2)^1.5
The radiometer boom is roughly 1 m long.
The maximum influence occurs at z = x/sqrt(2) = 0.7x, where the relative
influence is equal to 1/(sqrt(2)*1.5^1.5) = 0.385
The influence is 10% of its peak value at z = 5 m or a height of 21 m.
There are sonics at heights of 18 m and 23 m, so halfway between them
would be 20.5 m, where the influence is 12% of its peak value.
Andreas Held is installing his particle counter at the 14 m sonic.
According to Andrew, he can place it a "meter or so" above or below
the sonic, so we should put it as far below as Andreas thinks feasible.
Mounting his instrument at the height of the boom would have an
influence of 46% of its peak value. 1 m lower at 13 m would place it
3 m below the radiometers and reduce the influence to 25% of its peak value;
2 m lower at 12 m would reduce the influence to 15% of its peak value.
73: sonic, Site horizontal array, Fri 30-Mar-2007 14:00:19 PDT, sonic heights
I measured the heights of sonics in narrow array by using a theodolite to
measure the elevation angles of the top and bottom of the vertical,
'forward' face of the sonic 'box'. The height of this face is ~4.33 cm.
The theodolite was at a height of 1.82 m and 33.35 m in front of
the sonic 'box'. The sonics were at heights of 1.99 and 2.99 m
above the ground.
At a distance of 33.35 m (sonics7b,7t), the elevation angles of the sonics
above horizontal would be atan((1.99-1.82)/33.35) = 20 minutes and
atan((2.99-1.82)/33.35) = 2 degs.
3/31/07: Note that the distance of the TRH is
(33.35+1.08)/cos(Azimuth - Azimuth[7])
Data are Deg.min.sec
Sonic height = 1.82m + 33.35m*tan(90 - (bottom+top)/2)/cos(Azimuth-Azimuth[7])

Gordon's instructions for chaningin the config, e.g. when changing the

cd config
create the new xml, for example:
cp ops1.xml ops2.xml
edit ops2.xml, changing the heights of the sensors for
There are a bunch of them.
Also change the heights in the section
. There are
a bazillion of them (pays to have quick vi hands, or
you can do global changes with this vi command:
1116,1348s/9.6m/4.9m/g
where you figure out the line number range by looking at
the info line in vi.
Then you're done editing, check for syntax errors:
ck_xml ops2.xml
It will either report an error, or a long list of sensors and variables
names if things are OK.
edit configs.xml. Add an entry for the new config. Here are the
entries for ops1 and ops2. The times are in UTC. Note
that the times cannot overlap. Update the end
time of the previous ops.
To check the configs:
proj_configs -l configs.xml
Assuming the new operations period has started (the begin
time has passed) then shut down dsm_server:
ps -ef | fgrep dsm_server
kill -HUP pid
Then edit $ISFF/scripts/run_server.sh
to change the xml file (when I get the
time I can make that step unnecessary).
Then run it
$ISFF/scripts/run_server.sh
Then run statsproc:
$ISFF/scripts/run_statsproc.sh
Also edit Vazimuth.q as described in Entry #54.

53: leaf area index, Site all, Sun 25-Mar-2007 11:32:50 PDT, leaf area density profiles
Took out the LAI-2000 yesterday (3/24).
Drove the Cherry Picker south-ease down the angled road from
the yard until it turns east. I went south four trees.
First measurement is contained in file #6 on the logger. I did not
have a measuring tape at this time.
I then drove the cherry picker over to the 30m tower. At the tall
tower, I took three measurement profiles. Two were one tree north
of the tower and the last was three trees south of the tower.
The measurements were taken such that the LAI-2000 probe was located
at the top of the booms that hold the TRH sensors. These profiles
are contained in files #7, #8 and #9. In taking these measurements, I
had the sensor 90deg blocked (270deg open) to block me out of the
measurement. The highest measurement was at the 9m height because
the cherry picker would only go that high.
Returned this morning (3/25) to improve on the profiles taken yesterday.
These profiles were now taken from the eastern-most and western-most
towers of the horizontal array. I used the 180deg blocker for these
measurements to block both myself and the towers from the sensor.
The highest measurement for these profiles was 11m. I then took a
measurement every meter as I descended the tower. So there are now
twelve measurements per profile (from 11 -> 0 m). The good measurements
are contained in Files #13 (east, pointed south) and #14 (west, pointed
north).
I had to stop taking measurements because the sun came out. However,
in the future, I recommend another profile be take from the 30m tower.
I also recommend staying with this structure of once per meter.
To take the measurements:
1) power on by pressing: 'Power'
2) start logging data by pressing: 'Log'
3) press 'Enter' twice to take the entries as they are.
4) start at 11 m, point and level the sensor, press and let
go of the button on the wand. you'll hear a beep that
starts the measurement, followed by a beep that the
measurement is complete.
5) move down 1 m. repeat.
6) last measurement is with the sensor sitting on the ground.
7) the logger will store the info. Will offload later.
If you change the number of levels in the profile, you need to modify
the stored program.

$ISFF/cal_files/kryptonNNNN.
The ones in CHAT/ISFF/cal_files have names
corresponding to their location on the tower or array.
Those files just do an include "kryptonNNNN" on a given
date.
For example, krypton_3t.dat:
2007 Feb 10 00:00:00 include "krypton1133"
That means for cal data after Feb 10 look in krypton1133.
In krypton1133 is the complete cal history for 1133.
You can check the kryptonXXXX files in $ISFF/cal_files. They
should have Steve's latest values.
If one swapped in another kryton at 3t, say on Apr 13, you
would add another record to krypton_3t.dat, like so:
2007 Feb 10 00:00:00 include "krypton1133"

It will take 40 days to fill up east's pocketec, which has the
biggest data files I believe (1.5 Gbyte/day). pocketecs are 60 Gbyte.
The network is running well. I think we have 100% recovery on
the base system.
So, copying pocketecs is relatively low priority. Maybe once a week on
the tower, and on config changes on the array.
I need to create the script to copy the data and clear the pocketec.
The hotfilms are another matter, since we're not sending that data
over the net. The 3D system generates 6.2 Gbytes/day if left
running continuously. So one should swap that drive every week
or so if we run it often. The 5 1D probes generate 4.8 Gbyte/day.
There should have been two spare pocketecs in the hotfilm shipment.
If you think the trailer is safe from theft, then perhaps you
could leave isff7 connected, and we can do a daily copy from
isff1 to 7.

Recent sensor work:
Yesterday we replaced two sonics that were missing data, one at 6 m on the
30 m tower and 9b on the horizontal array. The problems we were having
were discussed with Larry Jacobsen at Campbell and this was a problem that
they had not previously seen. The sonics appeared to be periodically
resetting themselves due to an inability to process 60 Hz data quicky
enough. For sonic 9b, we had to lower the array in order to change the
sonic.
Yesterday we lowered the horizontal array, now at 10 m, in about 75 minutes
and raised it again in about 45 minutes.
On Wednesday, March 21, we replaced the 6 m TRH which was reading ~0.3 degC
too low.
On Sunday, March 18, we replaced the 9.6 m TRH on the horizontal array.

This morning, we replaced sonic 0740 at 6 m on vertical tower with sonic 0119.
Moved sonic 0740 to TRH boom at 1.70 m + 32 cm. Thus sonic is at a
height of 1.70 m + 32 cm + 5 cm = 2.07 m.
Plugged sonic 0740 into 1.5 m serial port, lower ttyS1.
17:55: plugged 1.5 m sonic, S/N 0673, back into lower ttyS1.
3/23: From missing kh2o data at 1.5m, I see that sonic 0740 was
on ttyS1 from 11:20 - 17:55 PDT
35: sonic, Site 30m tower, Wed 21-Mar-2007 18:04:38 PDT, Changed 6 m sonic "dc" parameter to 0
I talked with Larry Jacobsen at CSI about sonic sampling problem. It appears
that the sonic just can't keep up with 60 Hz. It does not miss samples at
30 Hz and Larry speculates that we might fix this by narrowing the time window
whithin which the sonic looks for the received signal (my interpretation of
what he told me). The way to narrow the window is to decrease the DC
parameter to 0, which is by default 1 for 60 Hz, using the terminal command
'dc -' (dc + increments DC). Note that the default DC parameter is larger for
slower sampling rates.
So far I have been unsuccessful reducing the DC parameter for sonic 9b while
it is misbehaving. I could presumably do it for sonic 6m because it was
behaving at the time.
In the process, I did not get the sonic going again until 18:12.
34: sonic, Site horizontal array, Wed 21-Mar-2007 14:43:18 PDT, restarted sonic 9b

28: rad_soil, Site 30m tower, Tue 20-Mar-2007 08:55:38 PDT, radiometer footprint
I have calculated the footprint for a downward looking radiometer:
The footprint is h^2/(r^2 + h^2)^2 where h is the height of the radiometer
and r is radial distance on the surface from a point immediately below
the radiometer. Thus the footprint has a maximum directly below the
radiometer equal to 1/h^2, drops to 0.5/h^2 at r/h ~ 0.6, 0.25 at
r = 1, and 0.01 at r=3.
The cumulative footprint is r^2/(r^2 + h^2). The cumulative footprint
equals 0.5 at r/h = 1, 0.9 at r/h = 3, and 0.99 at r/h = 10.

All previous CHATS data, and photos have been copied to it
from /data.
Current plans are to keep /media/isff1 permanently
mounted on the aster system.
A 400 Gbyte disk should arrive today. That will
be the backup disk. The plan is to do intermittent
copies to that disk, and bring it back to the hotel
for safe-keeping. With two backup disks, one could
be brought back to Boulder from time to time.

13: trh, Site horizontal array, Thu 15-Mar-2007 10:12:08 PDT, No 9.6m TRH data on horizontal array
We mounted the two TRH's on the center tower of the horizontal array yesterday.
We got data for some 10's of minutes for both, then the 9.6 m TRH stopped.
No T or RH data. 10.6 m is okay.
12: sonic, Site horizontal array, Thu 15-Mar-2007 10:09:37 PDT, Sonic 9b missing data??
The diagnostic variable from sonic 9b is above 25 for several hours at a time.
Gordon notes that this indicates the 5th bit is set, which occurs when
the sonic counter increments by more than 1 between recieved samples.
11: licor, Site horizontal array, Thu 15-Mar-2007 10:07:06 PDT, Licor h20 data
Gordon reparsed the Licor 7500 data. Now it is the h20 data from S/N
0813 that is ~ 1 gm/m^3 higher than the rest.
10: sonic, Site horizontal array, Wed 14-Mar-2007 16:29:37 PDT, sonic 8b
The U component on sonic 8b appears to be perhaps 10 cm/s too low. However the second moments look okay, e.g. , , etc.
9: licor, Site horizontal array, Wed 14-Mar-2007 12:42:10 PDT, Licor 7500 CO2 data
The CO2 data from S/N 0813 is ~50 mmol/m^3 higher than the newer Licor 7500's
with S/N 1163-1166.
3/15: Gordon fixed parsing on Licor. Now CO2 data agree much better, but the
h2o data from 0813 are now ~1 gm/m^3 higher than the rest.

5: sonic, Site horizontal array, Wed 14-Mar-2007 10:43:35 PDT, Horizontal array data, dimensions
We began collecting data from the horizontal array yesterday afternoon using
12 V batteries to power the system, since we are waiting for power cable to
install AC power. The main purpose was to collect data to see how
things are working.
Around 4-5 pm PDT we raised the array to 10 m. It is in the narrow
configuration with a sonic spacing of 50 cm. The tops of the sonic booms
are at 10.6 m and 9.6 m. The sonics are numbered 1-9 from west to east.
3/16/07
The sonics themselves are at 9.65 m and 10.65 m.
3/26/07
Note that the small horizontal array spans one row opening. Every year,
the orchardists trim (hedge) every third row. The location of the small
horizontal array was trimmed two years ago, so is one of the densest row
openings. The wide array will span two rows, one trimmed last year (east)
and the other trimmed two years ago (west).
3/27/07
Discovered today that the 7th sonic from the west is at the mid-point
between tree rows. Trees immediately south of the west array are 7.36 m apart.
4: rad_soil, Site 30m tower, Wed 14-Mar-2007 10:35:05 PDT, Soil sensor location, s/numbers
I installed the soil sensors at a depth of 5 cm, south of the sawhorse and at
the boundary between bare ground and clover. See previous logbook entry for
discussion of surface types. They are close to being directly west of a tree.
I installed the soil heat flux plate at 5 cm with the dot on top. I installed
the ECH2O and TPO1 sensors with a vertical orientation to avoid blocking
vertical water migration. I installed the soil temperature probe at a
45 degree angle starting near the surface.
The serial numbers are:
HFT 14983123 38.2 W/m^2 per V
Qsoil No serial number
TPO1 200239 175.8 uV/degK
Soil T STP 94017
3: rad_soil, Site 30m tower, Wed 14-Mar-2007 10:27:50 PDT, Installed sawhorse
The radiation sawhorse has been installed at the 30 m tower. It is
located one tree row north and 3 rows west of the tower.
There are two distinct types of surfaces. The surface between the trees in
a N/S row is bare ground. The surface between the N/S tree rows has a
ground cover of clover. I oriented the sawhorse in a N/S direction and
aligned the horizontal beam along a border between clover and bare ground
in order to sample equally both types of surface.
The height of the middle of the horizontal sawhorse beam is 2 m +/- a few
centimeters. It is 120 cm west of the tree line and centered N/S between
two trees.

Initial 'wireless' working
Still no power to array but a 'battery test' demo'd that the
comms from base to array/tower is working a nominal.
AP24 internal is on tripod next to base pointing under the
trees to eant-A roughly 75' north of the array. NOTE: this
uses a 10m 'serial' cable extension (ie extra capacitance bad)
to a ~40' cat5e cable.
AP24 external antenna is on top of 5section pam mast roughly
pointing to tall tower (180deg antenna)
