SGP/IRT25m/C1 - Reprocess: up_short_hemisp needs -1 multiplier
DataStreams:sgpirt25m20sC1.a0, sgpirt25mC1.00, sgpirt25mC1.a1, sgpirt25mC1.a2
Description:
The upwelling hemispheric shortwave measurement
   in the SGP.C1 IRT25m data streams for the time
   period noted requires a (-1) multiplier to correct
   for swapped connections at installation.

  • Instantaneous Upwelling Shortwave Hemispheric Irradiance, Pyranometer(inst_up_short_hemisp)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Maxima(up_short_hemisp_max)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Minima(up_short_hemisp_min)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Standard
    Deviation(up_short_hemisp_std)
sgpirt25mC1.a1:
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Minima(up_short_hemisp_min)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer, Standard
    Deviation(up_short_hemisp_std)

Subject:
SGP/IRT/C1 - Reprocess: Longwave Calibration error
DataStreams:sgpirt25mC1.b1
Description:
Modified pyrgeometer calibration procedures were implemented beginning in December 2003.  
These modified procedures introduced a calibration bias in the longwave data.  The 
previous procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations.                                                             
                The data collected while the incorrect procedures were in place are 
being reprocessing to remove the calibration bias.  Note, this also affected standard 
deviation, maximum and minimum data fields.
Measurements:sgpirt25mC1.b1:
  • Instantaneous Upwelling Longwave Hemispheric Irradiance, Pyrgeometer(inst_up_long_hemisp)
  • Upwelling (10 meter) Longwave Hemispheric Irradiance, Pyrgeometer(up_long_hemisp)
