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 maximum(precip_max) Precipitation standard deviation(precip_sd) Precipitation mean(precip_mean) precipitation minimum(precip_min)

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 maximum(precip_max) Precipitation standard deviation(precip_sd) Precipitation mean(precip_mean) precipitation minimum(precip_min)

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 maximum(precip_max) Precipitation standard deviation(precip_sd) Precipitation mean(precip_mean) precipitation minimum(precip_min)

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 maximum(precip_max) Precipitation standard deviation(precip_sd) Precipitation mean(precip_mean) precipitation minimum(precip_min)
