Description:
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.

Calibration results are available from the OMIS database at 
    
http://www.ops.sgp.arm.gov:591/smos6cal/default.htm

SGP/SMOS/E7 - Reprocess: Wind direction offset
DataStreams:sgp1smosE7.b1, sgp30smosE7.b1
Description:
When the SGP.E7 SMOS tower was installed it was not aligned
properly resulting in a 6 degree offset.  On 3/08/05, the
datalogger program was modified to correct for this offset.

SGP/SMOS/E7 - Rainfall Data Suspect
DataStreams:sgp1smosE7.b1, sgp30smosE7.b1
Description:
Rainfall during this time period was suspect as the gauge was found plugged on 11/28/2006. 
 Last check of site occurred on 11/14/2006.  Any rainfall data collected, whether the 
data is 0 or other than zero is suspect.

SGP/SMOS/E7 - Wind sensor binding at low wind speeds
DataStreams:sgp1440smosE7.b1, sgp1smosE7.b1, sgp30smosE7.b1
Description:
The wind sensor bearings were failing causing the wind speed sensor to report lower than 
actual wind speeds when the winds were below 2 m/s.  The wind monitor was replaced on 
05/29/2007 but this failed to correct the problem.  Subsequently, the site was flooded and it 
took some time to re-establish normal operations.  The wind sensor was again replaced on 
10/30/2007.  After replacement the wind data from the SMOS compared more favorably to 
the co-located EBBR data.

  • Time of Minimum Wind Speed(time_min_wspd)
  • Minimum of Wind speed(min_wspd)

SGP/SMOS/E7 - Incorrect Offset for Wind Directon
DataStreams:sgp1smosE7.b1, sgp30smosE7.b1
Description:
An incorrect offset of 6 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.

  • Unit Vector Wind Direction(wdir)
