SGP/SONDE/C1 - CF sounding 20020609:0229 bad temp/rh/etc
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The temperature and RH for this sounding look bad, either because of
interference from another sonde or because the temperature sensor was
broken on launch.  The sounding terminated early in any event.
Measurements:sgpsondewnpnC1.a1:
  • Dry bulb temperature(tdry)
  • Dummy altitude for Zeb(alt)
  • Relative humidity inside the instrument enclosure(rh)
  • Ascent Rate(asc)
  • Surface dew point temperature(dp)

sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Dry bulb temperature(tdry)
  • Relative humidity inside the instrument enclosure(rh)
  • Ascent Rate(asc)
  • Dummy altitude for Zeb(alt)

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 inside the instrument enclosure(rh)
  • Retrieved pressure profile(pres)
  • Dummy altitude for Zeb(alt)
