SGP/SMOS/E9 - 6-month Calibration Checks

During the time periods specified, the SMOS.E9 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 
    
http://www.ops.sgp.arm.gov:591/smos6cal/default.htm 
To view all 6-month calibration reports leave the date time entry blank.

SGP/MFRSR/E9 - Instrument not shading properly

A slight shading problem is first noticeable on 2/7/2006 late in the afternoon.  The 
shading issue grows progressively worse until resolved on 3/23/2006. Do not use diffuse or 
direct data between the hours of 1700 and 0100 UTC.  Note this range spans UTC midnight.
