TWP/SKYRAD/C3 - Reprocessed: Longwave Calibration error

Modified pyrgeometer calibration procedures were implemented beginning in December 2003.  
These modified procedures introduced a calibration bias in the longwave data.  The 
previous procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations.

The data collected while the incorrect procedures were in place were reprocessed to remove 
the calibration bias.  Note, this also affected standard deviation, maximum and minimum 
data fields.

Reprocessed data were archived 20100211.
