Subject:
AWR/GNDRAD/S1 - IRT failure
DataStreams:awrgndrad20sS1.a0, awrgndrad60sS1.b1
Description:
A heater malfunctioned and overheated the IRT causing it to fail. 

[The datalogger was using the wrong multiplier and offset. The values used were 26 K/V and 
173.2 K, respectively (same as SKYRAD), but the correct values are 25 K/V and 223.2 K, 
respectively.]
Suggestions: 
The surface temperature (sfc_ir_temp) measurements cannot be corrected.
Measurements:awrgndrad20sS1.a0:
  • Instantaneous Surface Infra-Red Signal(inst_sfc_ir_signal)
more
awrgndrad60sS1.b1:
  • Surface Infra-Red Temperature, Maxima(sfc_ir_temp_max)
  • Surface Infra-Red Temperature, Minima(sfc_ir_temp_min)
  • Surface infra-red temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature, Standard Deviation(sfc_ir_temp_std)
