I haven't exhaustively looked at all cases, but it appears that, at least for the "bad data" case 05:10-06:10 AM on 5 June at Platteville, dew formation caused the bad h2o and presumably co2 values. During this case, RH is at least 97% and w'h2o' fluxes during the preceeding hour are negative (water deposition to the surface).
I note that this occurred despite the Li7500 being mounted at 45 degrees upside down, but presumably dew on the mirror also would affect the signal.…
RH.6m at Marshall (TRH010) looks wrong from Jun 9 06:10 to 07:30 MDT. http://www.eol.ucar.edu/isf/projects/ASP09/isff/qcdata/plots/20090609/trh_20090609.png
8June09 ~10:00MDT
Platteville turned off, station returned to Boulder.
Since Jun 7 19:05 13:05 MDT Marshall adam was only recording the 2 inputs on the viper serial ports, not the emerald serial card. This is the PC104 interrupt issue that I thought I had fixed....
As a result we only have data from the 2m sonic (and GPS) from that time until the system was remotely soft-rebooted on Jun 8 09:04 MDT. It stayed up for 10 minutes and then hung. It was hard-booted at 10:00.
7June09 ~16:15MDT
Swapped Pocketec.
The area had some rain this afternoon and the Echo is reading ~34 now. Everything else seemed reasonable.
Data was uploaded in Boulder via porter.....
porter:/h/eol/militzer-> copy_pv_usbdisk.sh
usbdisk disk not mounted. Trying to mount /media/usbdisk...…
For two periods of an hour or more today, Rpile.in.mfs went to zero.
After trying to reseat connectors/wires in the logger box, the fix was simply to cut and restrip the wires inside the logger for the 2L/2H inputs.
6June09 ~16:15MDT
Swapped Pocketecs. Gordon merged.
Echo probe was reading ~ -67, tried the other probe more recently installed in the ground by CG, and it also was reading about the same. Left the original one connected to logger. Probably will be small spike in data from short swap.
Other data appeared reasonable from quick look.
now is 1731 MDT. We had a trace of sprinkles perhaps 1.5 hours ago as well. This is enough to hear on the roof.
Rsw.out was clearly dirty (and appears to have a few specks of something inside the dome as well). Rnet might have had a bit of dirt as well. Accessed the sensors by standing on the (only) folding chair from the trailer. This done 1538-1544 starting with Rlw.out and ending with Rnet.
We've seen some spikes in the Marshall CO2 data at 10m (also some at 4m). We've also observed a raptor using the 10m boom as a perch. (I tried to take a few photos.) I guess it it possible that the Licor is measuring raptor breath! I update the bird time when I download my photos.

Echo Probe swapped (these have no serial numbers): Previous unit was reporting negative values per TH. From raw file data from 'yesterday' was
182,1,12.27,0,15.173,0,-56.044,-4.6824,-2.2093,83191,8.9592,8.844,9.7848,9.6367,13.517,39.416,435.39,1.2594,0,0,-9999
where vqsoil,qsoil is '435.29,1.2594' Note the rsw values appear odd in that....
New unit per rserial is reporting messages like this:

Pocketec Swapped. Brought unit taken back for data merge.
Photos taken. Sensor serial numbers confirmed.
Q7 swapped: We had installed the 'wrong' Rnet for the coefficients in the logger. Out=Q94197 In=Q99259
3June06 ~10:30MDT
Rlw.in had been bad. Found loose ground wire on the excitation line. Twiddled/secured wires. Now working
Rlw.in Rpile reading ~ -20w/m2 with voltage ~ .2mV
Rlw.out Rpile reading ~ 20w/m2 with voltage ~ .2mV
3June06 ~10:15MDT
4m TRH swapped because it'd been bad (See GM's note) sn-out=13 sn-in=008 It was generating continuous spurious interrupts. Only the michro-chip 'wand' was replaced, not the shield.
6m TRH removed s/n15 because of bad 'shield' (dc-dc, sio, etc). Swapped 2m TRH up to 6m to avoid climbing later: sn10 is now at 6m

The Li7500 that was at 2m was raised to 4m per request by SO/TH.
It has the same serial port in xml config., but the height qualifier was changed from 2m to 4m also.
NOTE: Retained the mounting arrangement so we moved the sonic from 2 to 4 along with it,
and thus the 4m sonic to 2m as well. Will change the serial number entry for this
Recall setting 'ZN' on boom worked ok.
Boom Angle setup: BD359 as I recall....need to confirm KK's reading when he shot it.
Confirmed readings consistent with observed conditions, and manually rotating vane while mast was lowered.
The 6m RH deviates from the others when the RH is above 50 %.
4m TRH still not reporting. http://www.eol.ucar.edu/isf/projects/ASP09/isff/qcdata/plots/20090601/trh_20090601.png
4m TRH at Marshall started generating intermittent data starting around 00:00 LT, May 30, and appears to have quit altogether by 04:00
If you let it run long enough, data_stats shows a record length of 8191 bytes which indicates that the data system is not finding a terminator (newline) in the data:

-Q7 / Rnet installed. Verified data looked reasonable
- Local Storage Media swapped to check back at FL
- CSAT Boom Angle: KK says 88.9, Rudy says 91.5
29May09
The Rlw.in has been too warm for the last couple of days, producing erroneous looking data for rnet versus rsum.
Kurt cleaned the domes but did not see anything obviously unusual about the sensors or installation.
Keep-an-eye-on-it.

10m TRH's RH has been bad since it was installed yesterday. S/N16. Note SteveS mentioned he didn't get the raw data for the rh on this sensor, so it needs to be calculated and reprogrammed. For now we're doing the following:
2m TRH moved to 10m. S/N14
10m TRH s/n16 removed and swapped with TRH s/n10
