Subject:
MAO/GNDRAD/M1 - IRT bias
DataStreams:maogndrad60sM1.b1, maogndrad20sM1.a0
Description:
The surface temperatures measured by the IRT had a positive bias compared with the PIR. 
The IRT measured ~10K higher than the calibration blackbody. The IRT was replaced.
Suggestions: 
The data may be able to be corrected by deriving the regression against the PIR.
Measurements:maogndrad20sM1.a0:
  • Instantaneous Surface Infra-Red Signal(inst_sfc_ir_signal)
more
maogndrad60sM1.b1:
  • Surface infra-red temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature, Minima(sfc_ir_temp_min)
  • Surface Infra-Red Temperature, Maxima(sfc_ir_temp_max)
