after all computer boards were reseated and all electrical connections were 
reestablished.

SGP/RWP/C1 -  Reprocessed and Corrected: Missing Value Incorrectly Set
DataStreams:sgp915rwpprecipmomC1.a0
Description:
DATA REPROCESSED and CORRECTED:

In the moment datastreams (precipmom and wind mom) from the 915 RWP, the snr variable, is 
not set to missing value when the SNR is invalid but the other moments have valid values. 
At these points the SNR has a value of 32767. The ingest was updated and the data were 
reprocessed to fix the issue.

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