DataStreams:sgpkasacrspeccmaskcopolC1.a0, sgpkasacrspeccmaskxpolC1.a0, sgpkasacrvptC1.a1
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.

SGP/KASACR/C1 - Reprocess: Intermittent missing spectra data
DataStreams:sgpkasacrspeccmaskcopolC1.a0, sgpkasacrspeccmaskxpolC1.a0
Description:
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.

SGP/KASACR/C1 - Reprocess: Intermittent missing spectra data
DataStreams:sgpkasacrspeccmaskcopolC1.a0, sgpkasacrspeccmaskxpolC1.a0
Description:
During this period there are times when the spectra ingest and cloud masking processing 
failed, due to problems in matching raw spectra files with the appropriate raw moments 
file. It is believed that many of these remaining raw spectra files can be properly ingested 
when reprocessing is done, although there are cases where no valid moments data exist.
