Subject:
NSA/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:nsasondewnpnC1.b1
Description:
The output precision of the following variables was increased 20060929:

   alt	changed from 1m to 0.1m
   dp	changed from 0.1degC to 0.01degC
   pres changed from 0.1 hPa to 0.01 hPa
   RH	changed from 1%RH to 0.01%RH
   tdry changed from .1degC to 0.01degC

Note that the increase in precision does not necessarily imply an increase
in accuracy.  Users are cautioned to continue to use their best scientific
judgement when using these or any other data.
Measurements:nsasondewnpnC1.b1:
  • alt
  • Dry Bulb Temperature(tdry)
  • Dewpoint Temperature(dp)

Subject:
NSA/KASACR/C1 - Some spectra data was not being ingested and masked
DataStreams:nsakasacrspeccmaskcopolC1.a0, nsakasacrspeccmaskxpolC1.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.
