Subject:
SGP/SMOS/E7 - Wind sensor binding at low wind speeds
DataStreams:sgp30smosE7.b1, sgp1440smosE7.b1, sgp1smosE7.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.
Suggestions: 
Use co-located EBBR wind speed data when wind speeds are below 2 m/s.
