PVC/AOD/M1 - Reprocessing Notice (RID 1213)

See below for details of reprocessing that was completed on 20150220.  Original 
DQR category: 4 (Red, Incorrect).

-----------------------------------------------------------

For reasons not entirely understood the MFRSR AOD Value Added Product began to experience 
infrequent but serious data corruption issues.  This is evident in the data files from 
PVC as irradiance fields, calibrations, and AODs taking nonsense values ? sometimes NaN, 
Inf, or other values orders of magnitude out of bounds with normal behavior.  The behavior 
is sometimes abrupt with drastic changes observed from one day to the next, but not 
within a given day.  This behavior was not reproducible when reprocessing on the development 
system. 

We have developed a new version of the MFRSR AOD Value Added Product using a different 
library suite and have confirmed successful reproduction of the existing product when the 
existing product was not corrupt, and consistent    replacement of the corrupt periods with 
reliable results.
