SGP/SMOS/E9 - Bad Humidity Data
DataStreams:sgp1440smosE9.a0, sgp30smosE9.a1, sgp1smosE9.a0
Description:
During a rain storm the relative humidity readings (and vapor pressure
which is derived from RH) became erroneous.  The sensor electronics may
have gotten wet.  The sensor recovered from whatever problem occurred
e.g., the sensor dried out).  No permanent damage occurred.

No other measurements appear to have been affected.  Temperature
measurements during the period in question, agree with those obtained
by the EBBR.
Suggestions: 
All humidity data taken during the period in question, should be flagged
  as incorrect.
