Status of calibrations:
A. Radiation sensors (Analog).
Eppley Precision Spectrometer uplooking, SWI, psp.in.rad,
Eppley Precision Spectrometer downlooking, SWO, psp.out.rad,
Eppley Pyrgeometer uplooking, LWI, (pyg.in.rad, pyg.in.dome, pyg.in.case)
Eppley Pyrgeometer downlooking, LWO, (pyg.out.rad, pyg.out.dome, pyg.out.case)
Net radiometer, Rn, (net).rad
Analog calibration factors for these sensors are on file in the calibration lab.
Logbook entry 163 lists all these calibration factors.
They have been checked against those used in the
SJVAQS project prep.config file.
There was agreement except for the r.net where the wrong
calibration was entered. There has been a mix-up between
the two net radiometers and their calibrations. As the difference is only
0.75% the value will not be changed.
Calibration factors for the thermistors measuring the dome and
case temperatures are on file in the calibration lab.
Logbook entry 163 lists all these calibration factors.
They have been checked against those used in the
SJVAQS project prep.config file.
B. Soil heat flux plates (Analog).
The logbook entry 163 lists the calibration factors supplied by the manufacture.
Logbook entry 163 lists all these calibration factors.
They have been checked against those used in the
SJVAQS project prep.config file.
C. Soil temperatures (Serial).
The sensor calibrations were carried out and loaded prior to deployment.
We have verified that the 8 cm soil temperature sensors were interchanged.
The temperature reported for Tsoil8r corresponds to that for Tsoil8f and
the temperature reported for Tsoil8f corresponds to that for Tsoil8s.
D. Soil temperatures (Multiplexed analog).
The three multiplexed soil temperature arrays;
a(1,3,5,7), b(1,3,5,7),and c(1,3,5,7) each have complete sets of
thermistor coefficients which are noted in logbook entry 163.
For the purpose of generating real-time temperatures, however, only mean sets of
thermistor coefficients were used during the deployment.
For the post deployment data processing which involves de-multiplexing the
complete sets given in logbook entry 163 should be used.
E. Wind speed and direction (Serial).
The sensor calibrations were carried out and loaded prior to deployment.
The locations of the propvanes on the tower were verified during the deployment.
The alignment of the propvanes in the field was determined using a theodolite
twice during the SJVAQS deployment, after set-up and during teardown.
See logbook entries # and #.
F. Wet and dry temperatures (Serial).
The sensor calibrations were carried out and loaded prior to deployment.
The locations of the psychrometers on the tower were verified during the
deployment.
G. Pressure (Serial).
The sensor calibrations were carried out and loaded prior to deployment.
H. Sonic anemometers (Serial).
The despiked data is now available in stout/rdss/aster/projects/SJVAQS91/ops1
For the period before JD 204 use cal routine sonic_uw_4b
For the period after JD 204 use the cal routine sonic_uw_3b
I. AIR fast temperature sensors (Analog).
This data is alright
J. Krypton hygrometer (Serial).
This data is alright
K. Infra red CO2 sensor (Serial).
This data is alright
L. Fast ozone sensor (Analog).
Dick Pearson will provide the calibration factors for this sensor.
