SGP/SMOS/E13 - 6-month Calibration Checks
DataStreams:sgp1440smosE13.b1, sgp1smosE13.b1, sgp30smosE13.b1
Description:
During the time periods specified, the SMOS.E13 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/E27 - Wind Direction data incorrect
DataStreams:sgp1smosE27.b1, sgp30smosE27.b1
Description:
The wind direction sensor was reporting a consistent value of ~360 degrees during this 
time period.  Co-located and nearby sensors were not in agreement with these values.
Measurements:sgp1smosE27.b1:
  • Unit Vector Wind Direction(wdir)

SGP/EBBR/E20 - Reprocess: Wind Direction 65 Degrees Low
DataStreams:sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The wind direction sensor reported wind directions that were 65 degrees too low because of 
a mis-alignment.

This bias should have no effect on the res_ws or sigma_wd measurements.

The wind direction data could be re-processed by adding 65 degrees.
Measurements:sgp30ebbrE20.b1:
  • wind direction (relative to true north)(wind_d)
sgp15ebbrE20.b1:
  • Wind direction (relative to true north)(mv_wind_d)

SGP/SMOS/E27 - Incorrect Offset for Wind Directon
DataStreams:sgp1smosE27.b1, sgp30smosE27.b1
Description:
An incorrect offset of 7 degrees was added to 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.
