Subject:
SBS/GNDRAD/M1 - IRT bias
DataStreams:sbsgndrad60sM1.b1
Description:
The IRT was indicating lower surface temperatures than the PIR. It is unknown how the 
problem was corrected, but there was a concurrent increase in logger voltage of 0.02 V.
Measurements:sbsgndrad60sM1.b1:
  • Effective Surface (Skin) Temperature(sfc_ir_temp)
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)

SBS/SKYRAD/M1 - Noise in downwelling SW hemispheric
DataStreams:sbsskyrad20sM1.a0, sbsskyrad60sM1.b1
Description:
Downwelling Shortwave Hemispheric signal varies wildly between missing (-9999) and large 
positive values over this period.
