DataStreams:sgp1440smosE6.b1, sgp1smosE6.b1, sgp30smosE6.b1
Description:
During the time periods specified, the SMOS.E6 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

SGP/SMOS/E6 - SMOS Wind direction low
DataStreams:sgp1smosE6.b1, sgp30smosE6.b1
Description:
The wind direction reported by the SMOS went from being 7 degrees too low at the beginning 
of 2005 (the 7 degrees is a result of misalignment of the SMOS tower by 7 degrees) to 
15-20 degrees too small by November 2005.

The wind sensor was replaced, bringing the wind direction back to being 7
degrees too small.

SGP/SMOS/E6 - Wind Data Incorrect Due to Icing
DataStreams:sgp1440smosE6.b1, sgp1smosE6.b1, sgp30smosE6.b1
Description:
An ice storm caused the wind data from the RM Young wind sensor to be incorrect.  In many 
instances it was frozen and unmoving, at times it measured values but those are extremely 
suspect.

SGP/SMOS/E6 - Incorrect Offset for Wind Directon
DataStreams:sgp1smosE6.b1, sgp30smosE6.b1
Description:
An incorrect offset of 7 degrees was subtracted from the wind direction to correct for 
misalignment of the towers to true north. The wind direction data may be corrected but the 
vector averaged wind speed cannot. Subsequent audits have highlighted problems with past 
measurements of tower alignments.  All corrections to wind direction are being removed and 
Users are directed to view the Instrument Handbook for a table listing all tower 
alignment deviations from true north.  Users can adjust the data at their discretion.
Measurements:sgp1smosE6.b1:
  • Unit Vector Wind Direction(wdir)
