Here is what I think the Li7500 is reporting (I guess they are using g-moles):
H2OD - mmol/m3
convert to mass mixing ratio by:
H2OD (mmol/m3) * 0.001 (mol/mmol) * 18 (g_H2O/mol_H2O) / rho.air (kg_air/m3)
CO2D - umol/m3???
convert to ppmV by:
CO2D (mmol/m3) * 1000 (umol/mmol) * 28.97 (g_air/mol_air) * 0.001 (kg_air/g_air)
/ rho.air (kg_air/m3)
A plot of values converted this way is attached. H2OD is compared to Q and
CO2D is compared to co2mr. Everything seems in the right ballpark.
101: Snow_Precip, Site tower, Thu 27-Dec-2001 18:59:25 MST, New temp variable from snow depth gauge
The cr10 that is sampling the snow depth gauge also outputs
a temperature used in the calculation, which we have not been
parsing (and therefore does not appear in the archive).
At 17:25 MST Dec 26 cosmos was rebooted with a new sio_converter
for channel 201 which parses the temperature.
The new variable was first called Tsnow - which is perhaps a bad
choice since it isn't a snow temperature.
Later the snow depth variables were renamed and covars rerun back
to Dec 10. (In the field version of the netcdf files the original
names will still exist in files up to Dec 28).
depth.snow.main -> Depth.snow
Tsnow.main -> Tdepth.snow
99: Radiometers, Site tower, Wed 26-Dec-2001 12:02:22 MST, Rsw.in(main) odd
Rsw.in at the main tower has a lot of extra variation at night compared to sage
and compared to both Rsw.out. This has been going on for a long time -- perhaps
since the beginning. Could its fan be bad?
97: Snow_Precip, Site tower, Wed 26-Dec-2001 11:52:13 MST, temp sensitivity
I would guess that the snow depth gauge has a temperature sensitivity, though
perhaps it drifts as well. I just tried:
plot(dat("T")[,"T.1m"]*2.5+2100-dat("depth"),ylim=c(-200,200))
which looks like it removes some drift, but perhaps gives a signal which isn't
correct either.
Add to the list of one-time tasks:
- put stool under snow gauge
- let it sit for a period during which the temperature changes (several hours)
- remove stool
- log "stool" time in logbook

The TRH fans were swapped out with low-temp silicon oil.
86: Radiometers, Site tower, Mon 10-Dec-2001 13:36:09 MST, Change of sw.out at main
Between 11:50 - 12:10 at the main radiation site the down-looking K&Z was
swapped out
K&Z 940186 and its internal to the housing cable was removed.
K&Z 940181 and its associated cable was installed.
All domes were cleaned, all fans were checked and the Q7 checked for level.
The frost sensors were covered for a few minutes
Ninety minutes later the radiometer data were viewed. The new radiometer shows adata stream comparable to the corresponding data stream at the Bare Eve site.
85: CO2, Site tower, Mon 10-Dec-2001 11:02:03 MST, new licor7500 converter
On Dec 10, 09:36 MST cosmos was rebooted to install a
new sio_converter for the licor 7500 on channel 212.
Up until 09:36 we were using noconv_nl as the sio_converter
for the licor, which does no conversion and passes the
ASCII to the cal routine (licor_7500) to parse.
For efficency sake, were now using this sio_converter:
licor_7500 9 "(Data (Ndx %f)(CO2Raw %f)(CO2D %f)(H2ORaw %f)(H2OD %f)(Temp %f)(Pres
%f)(Aux %f)(Cooler %f))"
The cal routine is then the generic serial_float, though I imagine
we may have to create a special one if we want to convert the
units.
The licor periodically (once a second?) puts out a diagnostic
record, which will be ignored (and not archived). To see
the diagnostic record in real-time use rserial.
83: Radiometers, Site tower, Mon 10-Dec-2001 09:31:30 MST, level sensors temperature error
It is obvious that the level sensors at the main site respond inversely to
temperature -- about 1 angle degree to -0.03 C. Both X & Y show this behavior.
The little bit of data that I have from the bare site don't show this effect.
78: Radiometers, Site tower, Sun 09-Dec-2001 11:14:41 MST, rads serviced
I opened up Rsw.out to see if I could see a bad connection, but everything
looked okay. It was opened about 9:30 and closed about 11:00 and the ladder
was underneath, so this morning's data are bad.
I also attempted to clean Rsw.out with distilled water, but it immediately
froze. There still was ice on it when I left. The others I simply wiped with
a cotton swab.
77: Kryptons, Site tower, Sun 09-Dec-2001 11:12:03 MST, kryptons cleaned
Larry and I just cleaned all the kryptons, starting at 20m over the last hour.
Of course, we had to pull up the booms at 20 & 10, so sonic data will be bad.
75: Thermocouples, Site tower, Sat 08-Dec-2001 16:59:37 MST, replaced last thermocouples
I just put the last 2 good thermocouples in at the lowest 2 levels: 0.20 and
0.35m. I also removed the dead thermocouples from the top down to 8m.
Some were pretty well battered.
73: CO2, Site tower, Sat 08-Dec-2001 14:21:45 MST, li7500 up
I mounted OSU's LI-7500 yesterday about 2pm and connected it to cosmos:212.
We are archiving the data in unconverted ASCII until we can figure out a
different format.
I don't like the mounting for the LiCor's box. Currently, I have it just
sitting on a breakout box stand. At the very least, it should be bolted to
this stand....
I also did some CONFUSING cabling for this sensor. I have connected it to
MARIGOLD's Serial/Analog breakout box, to avoid adding another BOB. My
primary reason was to avoid running more DC power cable, since the LiCor takes
2 AMPS. A secondary reason was that we might connect it to marigold later
anyway, if Larry decides to move this sensor to 10m.
We still need to parse the message from this sensor. I've just put a generic
prep.config entry in for this sensor, commented out.
71: Soil, Site tower, Sat 08-Dec-2001 12:41:46 MST, soil samples
About 11:40 I took another core at the main site. I also took a nearby TRIME
reading of 10.4%. This time, I cleared a bare spot, but there were still a lot
of roots (one ~4mm diam.) in the sample, so most of the sample felt like peat.
The was separated into layers. The top cm was only partly filled, since the
sample was on a small local slope. I estimate the average depth in this as
0.5cm. Also, the bottom wasn't completely filled either. I estimate the depth
as just 2cm.
I simply weighed the total dirt sample (wet) in each of 4 layers to get the
total bulk density, then created alloquots to determine the soil moisture
after drying. The corer diameter is about 5.4cm

Shortly before he left, either 11/30 or 12/1, Steve Semmer swapped T/RHs at
2m. 004 replaced 703.
68: Soil, Site tower, Sat 08-Dec-2001 09:11:11 MST, soil samples
About 2:00 I took a core at the main site. I also took a nearby TRIME readings
of 5.7% and 6.9%.
I still had trouble unscrewing the corer when I got it back to the trailer, but
eventually got separated it out in layers. However, the top 2cm ended up being
above-ground grass, so the core was not as deep as it should have been. Also,
the first 3cm of ground, and even some of the next 3cm was mostly roots (like
peat).
I simply weighed the total dirt sample (wet) in each of 4 layers to get the

65: CO2, Site tower, Thu 06-Dec-2001 16:50:19 MST, flow rates checked
I just did the flow rate checks that Tony suggested. Each cal gas was turned
on for about 30 seconds at about 16:25. Note that I was standing near the
sonic during this period, so all fluxes at 2m are suspect.
nominal flow rate is ~5.5 lpm
flow rate with cylinder 1 is ~-2 lpm
flow rate with cylinder 3 is ~-2.5 lpm
These readings were so close to what Tony intended that I didn't change
anything.
But we still don't know why his gas is being used up relatively fast. I can
think of several possibilities:
- The flow rate out of the pressurized cylinders is more than through the
scintered inlet. I could check this by metering the analyzer outflow.
- There is a leak in the cal gas line. This strikes me as unlikely since both
cylinders are going down at about the same rate.
64: Thermocouples, Site tower, Thu 06-Dec-2001 14:50:05 MST, Lower thermocouples: changes to cr21x
The cr21x is now working in high resolution binary mode, as of 14:35 MST,
Dec 6. The cal routine is camp_hr_bin. To process the earlier data,
one would have to use the serial_float routine. If it is important
we will have to create a new ops period.
The binary data mode fixes the problem of the broken records
coming out of the cr21x - it was putting a carriage return after
8 fields in the ASCII output.

Procedure for soil samples during FLOSS01
At both sites, somewhere in the vicinity of the radiation stand/soil sensors,
take periodic soil cores for Bulk Density and for Soil Moisture.
Bulk density need only be done a few times at each site, but it would be good to do
soil moisture periodically.
I tried out the soil corer during set-up and found it to be a suitable method
for both Bulk Density and Soil Moisture
After using the corer clean it and wipe the threed with a WD40 tissue.
Note that the barrel need not be screwed in too tightly
Assemble the core with two 1cm sleeves then one 3cm sleeve and then the remaining
sleeves.
This will enable the top 5 cm to be separated from the core.
At the sample location, clean away the snow and loose dead grass.
Using the slide hammer pound the core into the soil until it bottoms out.
Work the corer back and foreward, left and right until it is loose.
Lift the corer out and carry it back to the base.
Use the plastic box in the tool box as a work area.
Unscrew the barrel of the corer and push out the sleeves containing the soil core.
Using the flat bladed tool separate the core at the 5 cm level.
To determine bulk density (and soil moisture):
Place entire 5cm core in one of the larger Al containers.
Weigh, setting the tare with a similar Al container.
Cook for two days in the oven at 110 C.
Reweigh.
From volume of the core (5cm x pi r^2 cm^2) and dry weight calculate bulk density.
From fresh weight and dry weight calculate the gravimetric water fraction.
(fresh wt - dry wt)/dry wt = gravimetric water fraction.
To determine soil moisture only (but more accurately).
After separating the top 5 cm of the soil core break up the soil mass and
homogenize it.
In three of the small Al containers (labelled A1,A2,A3, B1,B2,B3, C1,C2,C3) load ~
30g of soil.
Weigh, using a similar container as tare.
Cook for one day in the oven set at 110 C.
Reweigh.
From fresh weight and dry weight calculate the gravimetric water fraction.
(fresh wt - dry wt)/dry wt = gravimetric water fraction.

- 56: Radiometers, Site tower, Thu 06-Dec-2001 09:39:42 MST, checked Rsw.out
We noticed (belatedly) last night that Rsw.out.main has been bad. I reseated
cables this morning about 9:20 and did two tests about 9:30- 20 seconds with
my hand underneath followed by 20 seconds with the guy tension meter wood box
underneath. I'll look at these data soon.
With my hand, the value was 22 W/m2, with the box 18 W/m2, uncovered about
70 W/m2. Thus, it appears to be working now. I hope it stays that way.
- 55: Logistics, Site tower, Thu 06-Dec-2001 09:34:14 MST, guy wire tension

- 54: Thermocouples, Site tower, Wed 05-Dec-2001 13:57:46 MST, TC data from 21X
The data from the 21X is somewhat scrambled. Every other sample from the
thermocouples is 0. For the samples that the thermocouple is 0, the reference
appears to be a real value. The alternate samples appear to be good, with
a slowly varying reference and real thermocouple values.
Either we're not parsing the 21x data properly, or it is being driven too fast.
- 53: Snow_Precip, Site tower, Wed 05-Dec-2001 13:15:50 MST, precip gauge okay
The tips from the rain gauge during my calibration at about 12:35 were:
5, 7, 7, 7, 8, 7, 2 = 43 tips total
This sounds like a reasonable number. The CASES97 logbook says that we would
expect 44!
- 51: Status, Site tower, Wed 05-Dec-2001 12:54:23 MST, site visit
I spent the last 20 minutes at the main tower for daily stuff:
- dumped water in rain gauge (appeared to work!)
- shot 3 photos
- measured TRIME moisture 6.9 -> 7.4%
Now off to bare site for TRIME stuff and change wind gen pot.
- 50: CO2, Site tower, Wed 05-Dec-2001 12:11:51 MST, co2 calibration
I just looked at the CO2 calibration on 5 Dec 02:00. From an eyeball average
of values from prep, using a default gain of 190 and bias of 0:
cyl #1 - 317 => 334
cyl #3 - 484 => 472
Thus, the gain would be: 190 * (484-317)/(472-334) = 230
and the offset would be: 317 - 334*230/190 = -87
I'll go ahead and put these in, though we expect to generate a time-varying
calibration eventually.
- 49: Snow_Precip, Site tower, Tue 04-Dec-2001 23:16:03 MST, rainr
This afternoon (~4:00), I reseated the connectors for the rain gauge. I had
the idea that it wasn't completely seated at the CR10 side. Now, I see a single
tip which should have been due to the 1/4" of fluffy snow we just had. I might
have been tempted to try another calibration, but I didn't have any water left.
I've refilled it now and will try again tomorrow.
- 46: Snow_Precip, Site tower, Tue 04-Dec-2001 16:54:01 MST, added stool!
In a further attempt to check the snow depth gauge, I just placed the small
stool underneath it for about 5 minutes. The stool height is 11 7/8".
The change was obvious even in cockpit.
The numbers are:
2056-1764=292 (should be 300)

marigold was down from 19:45 to 22:28 today (when Gordon called me to tell
me it was down!)
This was during the time that Massman was setting up -- perhaps something was
bumped. (He was getting power from the box that the Breezecom is in.)
Sorry for not noticing this...

Notes:
1. The 23X data logger is at about 9m.
2. The 21X data logger is on the ground beneath the stairs.
3. The reference temp sensor from the 21X data logger appeared
to be noisy (need to talk to Steve Semmer about this).
4. Borrowed PVC fitting for the 21X Campbell Box from Larry/Dean.
(need to get them a replacement plus some putty-type stuff).
5. Three extra thermocouples are in a wooden red box in the ATD trailer.
6. Stored the following at the ATD trailer: (1) black plastic box
w/ thermocouple wire and 21X/23X manuals; (2) red wooden box with
extra thermocouples in them; (3) plastic tupperware box useful to
transport thermocouples up/down the tower.
7. On Saturday Dec 2 installed 4 thermocouples from 14-18.5m. The
following morning 2 of these thermocouples were broken.
8. When I left Sunday afternoon there was one broken thermocouple
(0.35m)...I think all the others were working. The wires breaking
are going to be a problem...possibly due to the low temperatures?
9. These are E-type (Chromel/Constantan) thermocouples with a
diameter of 0.0254 mm (1/1000 of an inch). Perhaps larger diameter
wires would be more tolerable of the cold...though we may lose
some response time.

where it listed the channel 13 value as "22553" it should be 22.553.
Also, I should have mentioned in my previous e-mail that the ref temp
of the data loggers is also recorded (in channel "0"). I also forgot
to mention about the open channels on the 21X data logger not
outputting "-99999"...instead they would output some random number
(which could possibly look real).
Is it possible to get a small 1-hz data file with some of the
thermocouple data in it? If this is a lot of trouble don't worry
about it...but I'm curious to see what is happening with the 21X
data...
- 40: Snow_Precip, Site tower, Tue 04-Dec-2001 11:40:19 MST, depth gauge check
I also put some 2x4 boards under the depth gauge from about 10:30-10:40. First,
about 1 min with 2" (1.5") thickness, then about 9 min with 4" (3.5") thickness.
Cockpit didn't show much change -- I'll look at data now.
The data appear to be:
2070 - pre test
1999 - 2x4 thin dh = 71mm (should be 38 + grass bed -- 33?)
1962 - 2x4 thick dh = 37mm = (should be 51)
2062 - post test dh = 100mm = (should be 51 + grass bed)
These aren't quite right. Also, I'm puzzled by the timing, since the "1999" values were before I did anything.
I'll try a slightly different test later.
- 39: Snow_Precip, Site tower, Tue 04-Dec-2001 11:38:20 MST, rain gauge cal
About 10:30, I dumped a whole bunch of water into the rain gauge, but didn't
see any response on the cockpit display. I'll look at the raw data to see
if I should have seen it.
I've looked at the data -- there were no non-zero values. Rain gauge data isn't
getting in.
- 38: CO2, Site tower, Tue 04-Dec-2001 11:16:59 MST, cal gas values

cal 1 317
cal 2 315
cal 3 484
cal 4 495
cal 5 493
cal 6 324 ppmV
We are currently using cylinders 1 and 3.
Bill Massman and John ? are now sniffing these as well.
- 36: Communications, Site tower, Mon 03-Dec-2001 17:07:03 MST, raised breezecom antenna
Tried raising the antenna a bit more on a round pole and aligned to the base

- 34: Adams, Site tower, Mon 03-Dec-2001 15:55:08 MST, unknown crash of marigold and cosmos
For some reason, both marigold and cosmos crashed. They both came back up with a "mxreset" apiece. Were Larry & Dean playing with power???
- 33: CO2, Site tower, Mon 03-Dec-2001 13:15:09 MST, cal gas amounts
We'll start to keep track of cal gas amounts here:
Cal 1(Lo) Cal 3(Hi)
01 Dec 20/1750 20/1630
03 Dec ?/1710 ?/1610
04 Dec 22/1610 19/1595 (~10:30; before Massman)

- 30: Thermocouples, Site tower, Mon 03-Dec-2001 09:34:07 MST, last value (20m)
Gordon had noted that if the last 23x thermocouple is missing, that the reported
value is -9, -99, -999, -9999 or -99999, which looked like some characters were
being clipped. This begged the question of whether characters were being
dropped from normal readings.
I've just looked at a few minutes of values using rserial and don't see any
characters being dropped from normal readings.
- 24: Sonics, Site tower, Sat 01-Dec-2001 17:47:23 MST, increased sampling rate on 20m sonic
data_stats showed that the 20 meter sonic was reporting at 20hz
instead of 60.
I changed it with rserial at 17:45 MST Dec 1,
using the campbell T and Ae commands:
rserial marigold 201
... hex output
enter "T" to put it in terminal mode
ctrl-D to get out of rserial
Run rserial in ascii mode:
rserial -A marigold 201
?? display status
Ae set it to 60hz
D back in data mode
binary gibberish
ctrl-D
- 23: CO2, Site tower, Sat 01-Dec-2001 17:19:58 MST, licor CO2 cal gas sequence
The co2 calibration is controlled by the ttl program in channel config:
# Tony wants a 2 minute calibration every 5 hours
# 17880 secs = 4 hours, 58 minutes
#
# adam datel_ttl_output unit chan start on off
#
cosmos datel_ttl_output 0 0 00:00:00 120 17880
cosmos datel_ttl_output 0 1 00:02:00 120 17880
TTL channel 0 controls the low cal gas valve, channel 1 controls
the high cal gas valve.
The low cal gas is 317 ppmV CO2, the high is 484 ppmV.
After cosmos is booted, it performs its first calibration at the
next multiple of 5 hours from 00:00 GMT of the current day, which
is at 05:00, 10:00, 15:00, 20:00 GMT or 01:00 the next day.
The sequence then repeats every 5 hours.
So assuming cosmos was booted at 17:00 GMT, the following sequence
would occur:
20:00 low cal gas
20:02 high cal gas
20:04 ambient air until 01:00 next day.
The next day the cal times will be an hour later:
01:00 same cal sequence
06:00
etc
Cosmos was last booted yesterday, Nov 30.
Tony connected the licor this morning, Dec 1.
I verified in the high rate co2mr.2m data that the calibration
sequence was done at 21:00 GMT today.

- 18: Adams, Site tower, Sat 01-Dec-2001 10:18:24 MST, Swapped ironics card in marigold
Arnica, the ironics card in marigold died last night.
This morning at about 10:00 MST the spare ironics (SN 422016)
was swapped in.
- 11: Adams, Site tower, Thu 29-Nov-2001 03:47:18 GMT, Ironics failures & light bulb heaters
The Ironics cards, both arnica and goldenrod, have been dying. They
stay up for a while, maybe 15 minutes or 2 hours, and then die.
Once goldenrod rebooted itself, but the adam code does not support
an ironics-only reboot, and so the serial data will not
get through.
One change from the testing at FLAB is the drop in the
internal adam temperature.
This afternoon we added some serial sensors to cosmos, so now
we can detect in the netcdf file if the ironics is running.
This evening after sunset Tbox.cosmos was dropping from 5.9 C.
At 3.6 C the ironics rebooted.
At 11/28 8:35 pm MST we placed a 40Watt bulb in the VME cage, between
the Datel and the filter board. Overnight Tbox.cosmos got up to
24C, with an outside temp of around -10C. The Ironics stayed up
all night!
At 10:00 am MST, 11/29, replaced the 40W bulb with a 7.5 W, and put
a 7.5W buld in marigold. were placed in both adams.
- 10: Status, Site tower, Thu 29-Nov-2001 02:25:48 GMT, Tower heights
I crudely set heights of booms today. Here is what I did (NOTE THE FUTURE WORK LISTED IN 7-9):
1. The wood beams for the tower base are 10cm high
2. The metal plates under the jacks are ~1.5cm thick (probably 1/2")
3. The height of the top of the tube at the top of the first ladder above the metal plates for each of the 4 legs were: 199, 196, 197, & 202 cm
4. I average the values in 3. and add to the values of 1. and 2. to get a nominal height above ground of the top of the first ladder of 210 cm
5. We measured the height of one section as 184cm
6. Thus, I get the following heights above ground of the top of the tube at the top of each of the ladder sections (in cm):
210
394
578
762
946
1120
1304
1488
1672
1856
2040
2224
2408
These are labeled using duct tape on the tubes.
7. We then attempted to position each of the sensors as close as possible to the specified sensor heights, 0.5, 1, 2, 5, 10, 15, & 20m. For the sensors up to 2m, we got to within 10cm by special clamping (still not perfect due to conflicts with brackets, etc. For the sensors above 2m, we should be within 50cm. We assumed that the sonics were 5cm above the boom, the props 50cm above the boom, and the T/RHs 50cm below the boom. Also, anemomber yokes make the boom height ~6cm lower than the tube it is clamped to and T/RH yokes (vertical) set the boom ~7cm from the bottom (or top) edge. Note that CSATs end up with the array almost perfectly aligned with the center of the tube that the yoke is clamped to. All these relative heights should be checked as well.
8. I'll have to measure the exact positions (still relative to the duct-tape labels) later.
9. Overall, I am reasonably comfortable with this approach. However, the 2m sonic will end up closer to 2.5m due to the tube available to clamp to. Also, the terrain to the south and west slope up a bit, so the sensors at the end of 3 and 4m long booms may be 10-15cm closer to the local surface. I'll try to determine this as well at a later time.

- 7: Adams, Site tower, Thu 15-Nov-2001 06:06:52 GMT, manual control of TTL ports
Three programs provide for manual control of the ttl ports on an adam.
The manual settings override what ever ttl program is running
on the adam (as specified in channel_config).
To return a ttl port to the control of the ttl program, use ttl_reset.
ttl_on adam ports... # Turns on one or more ports, numbered from 0-2
ttl_off adam ports...
ttl_reset adam ports # returns one or more ports to the normal
control of the ttl program.
Example:
ttl_on marigold 0 2 # turn on ports 0 and 2
ttl_off marigold 0 # turn off port 0
ttl_reset marigold 2 # put port 2 back under control of the adam
