Subject: | NSA/SKYRAD/C1 - Reprocessed: Incorrect calibration coefficient |
DataStreams: | nsaskyrad60sC1.b1, nsaskyrad20sC1.a0
|
Description: | Installed Skyrad PSP (downwelling shortwave hemispheric irradiance) had calibration
coefficient Rs applied when it should have used Rsc. ARM is using IR corrected Rsc and CFc
coefficients for PSPs deployed at all facilities.
PSP #32026 should use RSc@45=8.7578 ?V/W/m? and not Rs@45=8.6335.
Reprocessed to correct downwelling shortwave hemispheric irradiance (DS) by:
DS(new) = (DS(old) / 115.83 ) * 114.18
Reprocessing completed March 2008. |
