SGP/SMOS/E11 - 6-month Calibration Checks

During the time periods specified, the SMOS.E11 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.

Calibration results are available from the OMIS database at

SGP/SMOS/E11  - Reprocess: Barometer data factor of 10 too high.

The program was modified and an incorrect multiplier was used so that the barometer data 
was reported in hPa instead of kPa.
