MAO/WACR/M1 -  Reprocessed and Corrected: Incorrect polarization status

DATA REPROCESSED and CORRECTED: 

During this period, raw data was incorrectly identifying polarization status for hour-long 
periods, intermittently. So some hour-long periods were correct, and some hour-long 
periods had polarization status swapped. The ingest was modified to identify the good and bad 
hourly periods from reflectivity and linear depolarization ratio images. A new ingest 
software was released and the WACR data were reprocessed.

The data were Archived in July 2016. Please retrieve the reprocessed data for use in your 
analysis.
