Subject:
NSA/SONDE/C1 - Bad temperature
DataStreams:nsasondewnpnC1.b1
Description:
Because of strong winds, the radiosonde hit the ground after launch and the temperature 
sensor broke.  The RH and pressure data also should be considered suspect.
Measurements:nsasondewnpnC1.b1:
  • Wind Direction(deg)
  • wstat
  • alt
  • Northward Wind Component(v_wind)
  • Dewpoint Temperature(dp)
  • lon
  • lat
  • Humidity, relative(rh)
  • time_offset
  • asc
  • base_time
  • Dry Bulb Temperature(tdry)
  • Eastward Wind Component(u_wind)
  • Mean Wind Speed(wspd)
  • Pressure, atmospheric, constant value of model level, RUC model output(pres)

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.
