Subject:
NSA/WSACR/C1 - Reprocess: Incomplete spectra file processing
DataStreams:nsawsacrspeccmaskxpolC1.a0, nsawsacrspeccmaskcopolC1.a0
Description:
Raw spectra file sizes were being unintentionally limited due to an entry in a radar 
configuration file, causing spectra file splits during data collection.  However, the 
corresponding moments files were not splitting.  During the ingest and cloud masking processing, 
when spectra files were being matched with corresponding raw moments files, only the 
first spectra file in a vertically-pointing scan period was matching with the a moments file. 
 This caused the remaining (usually two) size-limited spectra files not to be ingested. 
Generally, spectra for only 10 minutes of each 25-minute vertically pointing time period 
have been ingested.	The remaining spectra files remain in raw format at the archive.
