Subject:
AWR/MPLCMASK/M1 - Reprocess: Software Error
DataStreams:awr30smplcmask1zwangM1.c1
Description:
The MPLCMASK VAP was expecting the MPL to be covered around local solar noon. As a result, 
the algorithm intermittently set much of the data to -9999 during this time period after 
the site transitioned to total darkness during the winter months. During the peak of 
this problem, the impacted fields were set to -9999 from approximately 0:00-2:19 UTC each day.

This information is being provided in a transparent DQR due to the intermittent nature of 
the problem and the fact that the impacted data are already set to -9999 and flagged by 
the automated quality control variables in the VAP. 

A future reprocessing task will correct this problem.
