Subject:
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 minimum(precip_min)
  • Precipitation mean(precip_mean)
  • Precipitation standard deviation(precip_sd)
  • Precipitation maximum(precip_max)

Subject:
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 minimum(precip_min)
  • Precipitation mean(precip_mean)
  • Precipitation standard deviation(precip_sd)
  • Precipitation maximum(precip_max)

Subject:
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 minimum(precip_min)
  • Precipitation mean(precip_mean)
  • Precipitation standard deviation(precip_sd)
  • Precipitation maximum(precip_max)

Subject:
SGP/ORG/C1 - False precip measurements
DataStreams:sgporgC1.b1
Description:
False measurements of precipitation occurred due to icing or conditions where the dew 
point temperature became close to the air temperature.
Measurements:sgporgC1.b1:
  • precipitation minimum(precip_min)
  • Precipitation mean(precip_mean)
  • Precipitation standard deviation(precip_sd)
  • Precipitation maximum(precip_max)
