Subject: SGP/WSACR/C1 - Reprocess: Intermittent missing spectra data
Affected Datastreams: sgpwsacrspeccmaskcopolC1.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.

Subject: SGP/WSACR/C1 - Reprocess: Intermittent missing spectra data
Affected Datastreams: sgpwsacrspeccmaskcopolC1.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.

Subject: SGP/WSACR/C1 - Reprocess: Mean Doppler Velocity sign reversed
Affected Datastreams: sgpwsacrcrrhiC1.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.
