SGP/SMOS/E7 - Wind sensor binding at low wind speeds

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.

SGP/SMOS/E13 - RH sensor failure

The T/RH sensor relative humidity data is suspect during this time.  Values from this

larger than the manufacturer suggested uncertainty of 3%.

SGP/SMOS/E27 - Wind data incorrect and/or suspect

A recent ice storm caused the wind speed and wind direction values to flat line to zero.  
Both values came back on 1/29/09, but wind direction flat lined at 355 degrees.  The wind 
direction values appear to recover on the 02/10/2009 but are still suspect.  The wind 
sensor was replaced on 02/24/2009.

SGP/SMOS/E9 - Wind speed incorrect

Wind sensor was reporting winds at 0 m/s for long periods of time. A loose connection was 
found and corrected.
