SGP/SMOS/E7 - 6-month Calibration Checks

During the time periods specified, the SMOS.E7 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.

Do not use data during these time periods.
