SGP/SMOS/E1 - Icing affected E1 SMOS wind speed
DataStreams:sgp1440smosE1.a0, sgp1smosE1.00, sgp1smosE1.a0, sgp30smosE1.a1
Description:
Icing conditions at E1 caused the wind speed to be questionable starting at
0600 GMT on 16 MAR 98.  By 1310 GMT, the icing caused the propellor to quit.
Recovery date and time unknown because power outage caused loss of data.  The
incorrect data and missing data are identified via other DQRs.

SGP/SMOS/E1 - 6-month Calibration Checks
DataStreams:sgp1440smosE1.a0, sgp1smosE1.a0, sgp30smosE1.a1
Description:
During the time periods specified, the SMOS.E1 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.
