NSA/MFRSR/C1 - Minor shading problem

There was a very minor shading problem when the instrument resumed banding after solar 
midnight.  This only affected a small portion of each day; not more than two hours after the 
instrument resumed banding after solar midnight.  7/9 is the best example of the 
problem.  The boundaries of this DQR are a little loose as the often cloudy conditions make it 
difficult to precisely say when the problem stopped.  Maintenance was performed on 9/5, 
but the problem was not visible sometime before that.

NSA/MFRSR/C1 - Reprocessed: Recalibration

The originally applied calibrations were bad.  Corrected calibrations were applied and 
reprocessed data were archived February 5, 2007.

(Note: these data were subsequently reprocessed again and archived in November 2007)
