Subject:	SGP/SMOS/E13 - Sensor failure
DataStreams:	sgp1smosE13.a1, sgp1smosE13.b1, sgp30smosE13.a1, sgp30smosE13.b1, sgp1440smosE13.a1
Description:	Beginning around 1415 UTC on 08/30, the RH readings for this instrument were frequently around 0 (sometimes there are erratic spikes upward from 0 for periods of time). Rainfall appears to have been the cause of the erroneous readings, as the instrument appeared to fail in and around the time of heavy rains. A maintenance visit occurred on 09/04, afterwards data returned to normal values.

Description:	During the time periods specified, the SMOS.E13 tower was lowered for 6-month Calibration Checks. During these times wind data are incorrect and temperature and humidity data may be incorrect. Note, exact times when tower was down or maintenance was being performed is sometimes unknown. Users should use the remaining data from these days with caution.
