SGP/SMOS/E13 - Sensor failure
DataStreams:sgp1440smosE13.a1, sgp1smosE13.a1, sgp1smosE13.b1, sgp30smosE13.a1, sgp30smosE13.b1
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.

  • Standard Deviation of Relative Humidity(sd_rh)

SGP/SMOS/E13 - 6-month Calibration Checks
DataStreams:sgp1440smosE13.a1, sgp1smosE13.a1, sgp1smosE13.b1, sgp30smosE13.a1, sgp30smosE13.b1
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.
