Licor affected by dew

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.

(This analysis was assisted by David Reed.)

RH.6m at Marshall (TRH010) looks wrong from Jun 9 06:10 to 07:30 MDT.

ISS data uploaded

All the mobile ISS data were copied with rsync from the site back to the FTP data directory as of 2009-06-08 04:00 UTC.

iss1:/> cd /iss/ds
iss1:/iss/ds> rsync -av ./ iss@shiraz.eol.ucar.edu:/net/ftp/pub/archive/iss/asp/iss1

This includes all the GAUS data, raw SPC, raw NIDAS, and NIMA SPC and netcdf.

Platteville TearDown

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.....

Daily Report for Sat 6 June 2009
MISS at Marshall for ASP mini-field project

Fine, mainly sunny with light winds.  Around mid-day on some mid-level clouds and widelyscattered low level CU.  Also some high level cirrus.  Less haze than yesterday.  Brief brisk westerly breeze around 2330Z.

Four soundings 15Z, 18Z, 21Z and 0Z :
15Z was relaunched as first sonde string separated from RS92 unit.
21Z 7C temperature bias (high) on pre-launch checks.  String didn't fully unwind so winds may be a little noisy.
0Z Lost GPS at launch.  It was tracked visually to about 350mb flying in an almost striaght line at approx 60 deg azi and 60 deg elevation.
18Z and 21Z showed some evidense of gravity wave breaking in winds at upper levels.

Wind profiler mainly only seeing boundary layer scatter.  Ceilometer seeing clouds around 4 - 5 km most of afternoon.

Rlw.in fixed

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.

Daily Report from MISS at Marshall in support of ASP mini-project

Fri June 5, 2009

Wave clouds over Bouler this morning, with increasing mid-level clouds during the day.  Light southerly and easterly winds.  Quite hazy. Late afternoon a thunderstorm with lots of lightning and oaccaionally heavy rain passed over.

Four soundings were launched : 1500 1730, 2030, 2330 UTC.   All soundings went well with  ASP students in attendance.  Boundary layer appeared to be low (400 - 600m) in all cases.  1730 and 2030 showed evidence of gravity wave breaking at upper levels (above 100 mb).  2330 sonde was launched as the thunder storm approched and appeared to travel along with the storm to the NE.

Wind profiler worked well although not seeing much above the low boundary layer.  During the early part of the storm there were cases of unusally clear separation of precip and clear-air signals in the Doppler spectra.

Surface station showed westerlies last night, not seen in the profiler so must have been low level, may be drainage flow out of Eldorado canyon.

[Gary created this log entry from Bill's comment added to the wiki front page]

Light rain started now

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.

CO2 from birds?

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:

182,1,13.24,0,464.1,0,-47.208,23.373,820.48,127.9,19.809,20.507,17.573,17.611,19.076,-61.372,423.8,.45439,0,0,-9999
182,1,13.24,0,513.61,0,-45.46,24.308,1005.7,152.81,19.809,20.603,17.573,17.632,19.055,-61.26,423.8,.45439,.00335,0,-9999

where the vqsoil/qsoil is the '423.8,.45439' versus '435.39,1.2594' above.   Meanwhile Mars is reporting:

166,2,11.55,0,521.44,0,-88.63,29.675,820.27,127.64,1.0656,23.434,1.1063,22.442,23.388,-86.93,509.36,6.4007,.02996,0,-9999\r\n
166,2,11.56,0,539.42,0,-88.63,29.675,867.57,131.35,1.0656,23.434,1.1066,22.435,23.368,-86.806,508.69,6.3538,.02996,0,-9999\r\n
with vqsoil, qsoil '508.69,6.3538'

So it appears maybe all these qsoils are about the same so I'm not convinced it is fixed....checking logger coef.....

Calib. Coefs in loggers: Location 45,46,47 are for the Qsoil and are the same for both loggers....guess we'll just need to keep an eye on it...

4June09 ~10:15-11:15MDT

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

NIMA crashing

NIMA is crashing on the ISS, so the plots of the improved spectra and winds will not be available until it is fixed. I'm trying to upgrade to the latest source and rebuild it to see if that fixes the problem.

As of yesterday, around 2009-06-03 18:00 UTC, the mobile ISS is up and running at Marshall. Real-time plots are available at this page:

http://www.eol.ucar.edu/isf/projects/asp/iss/realtime/summary/iss1/

The Internet link uses an etherant (ip 192.168.12.37) to the ISFS base trailer. The ISS workstation uses DHCP for its eth1 interface, and so far it has been assigned 192.168.12.250. Interface eth0 is the local trailer network, 192.168.1, on which the ISS profiler PC, sounding laptop, and ceilometer laptop are connected. The aster machine is at 192.168.13.1, which provides the routing gateway and DNS to the ISS workstation.

The network has been reliable so far, and data are flowing every half hour from the ISS site.

A web page for ISS for the ASP colloquium has been created here:

http://www.eol.ucar.edu/asp/iss

Rlw.in 'fixed'

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

RMY Boom Angle - PV

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.

6m RH bad above 50%

The 6m RH deviates from the others when the RH is above 50 %.

4m TRH still not reporting.

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:

marshall:/dev/ttyS11 2 410 1 2009 06 01 17:18:06.062 06 01 17:18:06.062 nan 0.000 0.000 8191 8191

data_dump shows that the data is all NULLs (0x00):

cd /data/projects/ASP09/raw_data:
data_dump -i 2,410 -A isff_20090601_160000.dat

The serial driver is reporting a bazillion "break" events for that port:

I recommend temporarily connecting a working TRH to port 11 and see if things look good.

At May 30 09:32 UTC (03:32 MDT) this TRH died until 03:49 MDT, then
looks like it reset itself, and worked until 03:56 MDT, and then died
completely. It did this same thing several times between 00:00
and 03:32 MDT.

Rlw.in at Mars

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.

TRH swap at Mars

29May09 ~12:00 MDT

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

9/29/09 15:00 MDT (TWH)  RH profiles, including RH at 2m and 10m, look fine at the moment.  It's a good time to check the profiles because they are close to constant with height due to good afternoon mixing.  Swap seems to have worked great.

There is now a shared ISS operator account through which students and operators can log into the wiki and make log entries.  See Gary for the credentials.

The "aster" laptop in the ISFS trailer is accessible from inside the UCAR firewall at 128.117.81.3

ssh aster@128.117.81.3

From there one can ssh to the adam:

ssh root@marshall

The adam is on the 802.11 (wifi) subnet at 192.168.12.115.
