Subject: | NSA/GNDRAD/C1 - Reprocessed: Incorrect calibration coefficient |
DataStreams: | nsagndrad60sC1.b1, nsagndrad20sC1.a0
|
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. |
