SGP/SMOS/E13 - Questionable E13 SMOS humidity data APR - NOV 95
DataStreams:sgp30smosE13.a1, sgp1smosE13.00, sgp1440smosE13.a0
Description:
When the E13 SMOS naturally aspirated radiation shield was replaced with a fan aspirated 
radiation shield on 14 APR 95 at 2030 GMT, the new shield was not adequately sealed to 
prevent penetration of water, whether from rain or from dew, from entering the radiation 
shield and causing incorrect humidity data.

After numerous attempts, the radiation shield was successfully sealed early in NOV 95.
Separate DQR's have been issued for humidity data that was obviously erroneous, but on 
numerous occasions during that period the humidity data has looked suspicious (e.g., see PIF 
P960624.1).

Therefore, all humidity data reported by the E13 SMOS during that period should be 
considered questionable.
