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:
  • alt
  • Dry Bulb Temperature(tdry)
  • Dewpoint Temperature(dp)
  • Humidity, relative(rh)
  • Pressure, atmospheric, constant value of model level, RUC model output(pres)

SGP/ORG/C1 - Frost on lens
DataStreams:sgporgC1.b1
Description:
Frost build up on the instrument lenses caused a faulty precipitation measurement.
Measurements:sgporgC1.b1:
  • Precipitation maximum(precip_max)
  • precip_sd
  • Precipitation mean(precip_mean)
  • Precipitation minimum(precip_min)

SGP/ORG/C1 - Lens heater failure
DataStreams:sgporgC1.b1
Description:
Any measurements made in freezing conditions are suspect due to failure of the lens 
heaters.  Users of the data can use the SMOS E13 data to determine if temperatures below 0 
degrees C occurred.
Measurements:sgporgC1.b1:
  • Precipitation maximum(precip_max)
  • precip_sd
  • Precipitation mean(precip_mean)
  • Precipitation minimum(precip_min)

SGP/ORG/C1 - Erroneous precipitation observations
DataStreams:sgporgC1.b1
Description:
Precipitation observed by the optical rain gauge was not observed by the SMOS tipping 
bucket or by the disdrometer nearby.  The optical rain gauge results should be considered 
erroneous.
Measurements:sgporgC1.b1:
  • Precipitation maximum(precip_max)
  • precip_sd
  • Precipitation mean(precip_mean)
  • Precipitation minimum(precip_min)
