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:
  • Relative humidity inside the instrument enclosure(rh)
  • Dry bulb temperature(tdry)
  • Dummy altitude for Zeb(alt)
  • Retrieved pressure profile(pres)
  • Surface dew point temperature(dp)

Subject:
NSA/SONDE/C1 - Temperature sensor broke at launch
DataStreams:nsasondewnpnC1.b1
Description:
The temperature sensor on this sonde broke at launch.  As a result all the thermodynamic 
data are incorrect.  The wind data are OK, though there will be some uncertainty in the 
altitude values.  This sounding was done at a non-standard time and it isn't clear whether 
it was delayed for some reason or a RHUBC sounding.  In either case, there is no fix.
Measurements:nsasondewnpnC1.b1:
  • Ascent Rate(asc)
  • Relative humidity inside the instrument enclosure(rh)
  • Dry bulb temperature(tdry)
  • Dummy altitude for Zeb(alt)
  • Surface dew point temperature(dp)
