Subject: | TWP/GNDRAD/C2 - Reprocessed: Incorrect calibration |
DataStreams: | twpgndrad20sC2.a0, twpgndrad60sC2.b1 |
Description: | The Gndrad PSP was changed out 11/25 but the datalogger program was not updated until 11/30. PSP #31293 installed 20071125.2202. Correct calibration coefficient = 123.46. Reprocessed to correct upwelling shortwave hemispheric irradiance (US) by: US(new) = (US(old) / 123.56 ) * 123.46 Reprocessing completed March 2008. |
