Subject:
SGP/SMOS/E20 - 6-month Calibration Checks
DataStreams:sgp1smosE20.b1, sgp30smosE20.b1, sgp1440smosE20.b1
Description:
During the time periods specified, the SMOS.E20 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.
Suggestions: 
Do not use data during these time periods.
