Subject:
TWP/XSACR/C3 - Reprocess: Intermittent missing spectra data
DataStreams:twpxsacrspeccmaskxpolC3.a0, twpxsacrspeccmaskcopolC3.a0
Description:
During this period, raw spectra file sizes were being unintentionally limited in length 
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 a moments file.  This prevented the remaining size-limited spectra files from 
being ingested. These spectra files do exist in raw format at the archive.
Suggestions:
