Subject:
TWP/SKYRAD/C2 - Reprocessed: Incorrect calibrations
DataStreams:twpskyrad20sC2.a0, twpskyrad60sC2.b1
Description:
The SKYRAD PSPs were changed out 11/25 but the datalogger program was not updated until 
11/30.

Reprocessed to correct calibration per:
  down_short_diffuse(corrected) = down_short_diffuse(orig) * (118.18/112.42)
  short_direct_normal(corrected)= short_direct_normal(orig) * (122.20/118.11)
  down_short_hemips(corrected) = down_short_hemisp(orig) * (133.16/137.57)

Reprocessing completed March 2008.
