SGP/SMOS/E24 - RH values exceeding the specified maximum value
DataStreams:sgp1440smosE24.a0, sgp1smosE24.a0, sgp30smosE24.a1
Description:
Starting on 29 OCT 96, the SMOS at E24 started reporting RH values
      exceeding the specified maximum value.  Lower values of RH may be
      within tolerances.  On 7 NOV 96 during the 6-month Sensor Verifications,
      the T/RH sensor reported a value of 31% RH that agreed with the reference
      within specified tolerances.  The probe continued to report values which
      exceeded 104% and was replaced on 11 FEB 97 at 1930 GMT.  Reported
      values since then appear to be within tolerances.

DataStreams:sgp1440smosE24.a0, sgp1smosE24.00, sgp1smosE24.a0, sgp30smosE24.a1
Description:
The output from the relative humidity probe on E24 SMOS drifted low by as much
as 5% when RH exceeded 80% by 15 OCT 97. The probe was replaced on 10 FEB 98
at 1900 GMT.  The replacement probe reported values approximately 10% too high
when RH exceeded 90%. That probe was replaced at 1830 GMT on 10 MAR 98.
