Subject:
SGP/THWAPS/C1 - RH Sensor Calibration
DataStreams:sgpthwapsC1.b1
Description:
The analog output for the T/RH probe was incorrectly calibrated.  This
caused excessively high readings of RH.
Measurements:sgpthwapsC1.b1:
  • Pressure, vapor, 60-m height, 30-min intervals(vap_pres)
  • Humidity, relative, 30-min intervals, standard deviation(sd_rh)
  • sd_vap_pres
  • Humidity, relative(rh)

Subject:
SGP/THWAPS/C1 - Minor bias in saturation vapor pressure
DataStreams:sgpthwapsC1.b1
Description:
The saturation vapor correction when temps are below 0C contained an error
in the multiplier.  The incorrect multiplier only equates to an error of
0.01 kPa which is less than the stated uncertainty of the measurement (+/-
0.035 kPa).
