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.
