Subject:
PVC/GNDRAD/M1 - Reprocess: Incorrect calibration
DataStreams:pvcgndrad20sM1.a0, pvcgndrad60sM1.b1
Description:
Incorrect program used in Gndrad since PVC deployment period began.  The Gndrad program 
was corrected 10/04/2012 approx 20:17GMT.  Reprocessing will be required of the upwelling 
PSP (up_short_hemsip). This will require applying the following corrections for the time 
range specified.
Serial number:
serial number(original) = 30938
serial number(corrected) = 37297

Data:
up_short_hemip(corrected) = up_short_hemisp(original)*(113.25(new cal)/129.42(old cal))
Measurements:pvcgndrad60sM1.b1:
  • Upwelling Shortwave Hemispheric Irradiance, Unventilated Pyranometer, Minima(up_short_hemisp_min)
  • Upwelling Shortwave Hemispheric Irradiance, Unventilated Pyranometer, Maxima(up_short_hemisp_max)
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
  • up_short_hemisp_std

Subject:
PVC/GNDRAD/M1 - IRT failure
DataStreams:pvcgndrad20sM1.a0, pvcgndrad60sM1.b1
Description:
The IRT failed but continued producing a misleading analog signal. The ground surface 
temperature measurements were unrepresentative of the actual temperature.
Measurements:pvcgndrad60sM1.b1:
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • sfc_ir_temp_std
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
