Subject:	SGP/SMOS/E6 - Sensor failure
DataStreams:	sgp30smosE6.b1, sgp30smosE6.a1, sgp1smosE6.b1, sgp1smosE6.a1, sgp1440smosE6.a1
Description:	On 08/30, after heavy rains had fallen, the RH sensor began occasionally reporting readings of around 0 or erratic data. Although frequently readings appearred reasonable, they unpredictably dropped or become erratic again for long periods of time. The sensor was replaced on 09/11/2003 @ 16:40 GMT.
