NSA/SKYRAD/C1 - Reprocessed: Incorrect calibration coefficients

On 7/20/2011 starting 2229GMT ops replaced the Skyrad shortwave instruments (PSP/8-48/NIP) 
corresponding to the datastreams (down_short_hemisp, down_short_diffuse_hemisp, 
short_direct_normal) but the calibration coefficients weren't changed until 07/25/2011 1842GMT.  

Data were reprocessed and archived in September 2011.
