Subject:
NSA/GNDRAD/C1 - Reprocessed: Incorrect calibration coefficient
DataStreams:nsagndrad20sC1.a0, nsagndrad60sC1.b1
Description:
Installed Gndrad PSP (upwelling shortwave hemispheric irradiance) had calibration 
coefficient RS applied when it should have used Rsc.  ARM is using IR corrected coefficients 
Rsc@45 and CFc@45 for PSPs deployed at all facilities.  

PSP #32012F3 should use RSc@45=109.39 and not Rs@45=110.97.  

Reprocessed to correct upwelling shortwave hemispheric irradiance (US) by:
US(new) = (US(old) / 110.97 ) * 109.39

Reprocessing completed March 2008.
Measurements:nsagndrad20sC1.a0:
  • Instantaneous Upwelling Shortwave Hemispheric Irradiance, Pyranometer(inst_up_short_hemisp)
nsagndrad60sC1.b1:
  • 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)
  • Upwelling (10 meter) Shortwave Hemispheric Irradiance, Pyranometer(up_short_hemisp)
