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)

Subject:
SBS/GNDRAD/M1 - Upwelling Shortwave data incorrect
DataStreams:sbsgndrad20sM1.a0, sbsgndrad60sM1.b1
Description:
Upwelling shortwave signal is flat (0 W/m^2) from 1532 UTC on 2010-09-24 through 1636 UTC 
on 2010-09-28 when it jumps to 600W/m^2. 

Value jumps between 800 W/m^2 and -9999 (missing) until 1833 UTC 2010-09-28.

Signal is adjusted downward ~250 W/m^2 at 2208 UTC on 2010-09-28. 

Data during the specified period are incorrect and cannot be corrected.

SBS/GNDRAD/M1 - Upwelling longwave initial problems
DataStreams:sbsgndrad20sM1.a0, sbsgndrad60sM1.b1
Description:
The Upwelling Longwave signal was not present in the datastreams until 1746 UTC on 
9/23/2010. The signal was then very noisy and frequently above empirical limits (575 W/m^2) 
between 1700 and 2200 UTC until 2208 on 9/28/2010 when it was adjusted upward about 50 W/m^2.
