SGP/SIRS/E7 - Reprocessed: Corrected Downwelling Longwave calibrations

Incorrect DIR calibration coeffs and serial numbers were applied to the data from 
11/02/2004 when the shortwave instruments were changed out.  Field techs corrected the program 
during longwave instrument replacement on 2/22/2005.

The data were reprocessed in September 2006 to apply the correct calibrations.  The 
reprocessed data were archived in October 2006.
