TWP/GNDRAD/C2 - IRT signal
DataStreams:twpgndrad60sC2.b1
Description:
When the other GNDRAD radiometers were replaced on 12/3/2006, the quality of the IRT 
signal began to degrade until 12/26 when it became unusable. The instrument was replaced on 
2/4/2007.
Measurements:twpgndrad60sC2.b1:
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • Effective Surface (Skin) Temperature(sfc_ir_temp)

Subject:
TWP/GNDRAD/C2 - Reprocess: IRT calibration
DataStreams:twpgndrad60sC2.b1
Description:
The configuration of the IRT was set to that used at TWP/C3. This caused the calibration 
of the data to be wrong. It was corrected by reconfiguring the IRT to match the datalogger 
program.
   
These data can be reprocessed and corrected by adding 10K, i.e. sfc_ir_temp(new) = 
sfc_ir_temp(old) + 10K.
Measurements:twpgndrad60sC2.b1:
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
