nsakasacrspeccmaskxpolC1.a0, nsakasacrvptC1.b1
Description:
The signs of the mean_doppler_velocity field values are incorrect.  The ARM convention 
for this field is that positive velocities indicate motion away from the radar.  However, 
the velocity data in these files have their signs reversed, so that motion TOWARD the 
radar has a positive sign.

NSA/WSACR/C1 - Some spectra files were not being ingested and masked
DataStreams:nsawsacrspeccmaskcopolC1.a0, nsawsacrspeccmaskxpolC1.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 mmoments 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.
