Subject:
SGP/SONDE/C1 - Broken temperature sensor
DataStreams:sgpsondewnpnC1.b1
Description:
The temperature sensor broke at launch on this sounding.  All of the temperature-related 
data (tdry, rh, dp) are incorrect.
Measurements:sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Dry-Bulb Temperature(tdry)
  • Relative humidity scaled, by total column amount from MWR(rh)

Subject:
SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:sgpsondewnpnC1.b1
Description:
The output precision of the following variables was increased 20060928

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:sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Dry-Bulb Temperature(tdry)
  • Relative humidity scaled, by total column amount from MWR(rh)
  • pressure at constant pressure surface(pres)
  • altitude above sea levelaltunits(alt)
