- 208: Radiation, Site stn1, Fri 14-Dec-2001 11:35:04 MST, Tear-down documentation of radiometers
This information has been transcribed from my CASES97/99 field notebook.
At tear-down I went around the four surface radiation sites and removed
the radiometers and the soil sensors. I made field notes at the sites.
The notes were made on Saturday, 30 Oct''99, or possible the next day.

- 145: SoilSensors, Site stn1, Wed 20-Oct-1999 10:21:27 CDT, Gsoil at station 1 fixed
The Gsoil cable was providing food for some hungry creatures.
The bad section of cable was removed and a splice was made.
The sensor looks good now.
NOTE: The change in cable may affect the calibration. data should
be viewed with caution.
- 66: Kryptons, Site stn1, Sat 09-Oct-1999 21:36:42 CDT, looked at krypton voltage
I just disconnected the krypton from stn1 for a few minutes while checking
its voltage level (quite low: 0.090 V). It is reconnected now. This
done about 2115 local.
- 56: Radiation, Site stn1, Fri 08-Oct-1999 12:32:09 CDT, Corrections for radiometer deployment errors
I inventoried the surface radiometers to investigate the cause for
some anomolous long wave data:
Station Rnet Pyg.in Pyg.out Psp.in Psp.out
1 97034 29260 26416
2 94197 31977 31981 940181 940187
3 94125 31975
5 97035 31979
This showed that the radiometer arrays on stations 1 and 2 were
interchanged when deploying them at the end of the intercomparison
period. This morning (Oct 8) we entered into the CR10 loggers at
stations 1 and 2 the coefficients corresponding to the radiometers
mounted there.
WARNING WARNING WARNING WARNING WARNING WARNING
Be aware that the labeling of the radiometers at stations 1 and 2
is different for the intercomparison than it is after the radiometers
were deployed at the various PAM stations.
WARNING WARNING WARNING WARNING WARNING WARNING
The coefficients for the PSPs at station 2 were entered around 9:30
am local time.
The coefficients for the PYGs at station 1 were entered around 10:55
am local time.
The coefficients for the PYGs at station 2 were entered around 11:10
am local time. At that time we found that the signal cables for the
two PSPs were interchanged and this was corrected at the CR10.
At station 5 we found a small error in the third coefficient of the
Tcase.pyg.out calibration. The data sheet lists a coefficient of
-6.90295 and the CR10 has a coefficient of -6.9229. It was decided
to leave this coefficient as we found it, since this value was used
during the field intercomparison of the radiometers.
