SGP/SMOS/E21 - Wind Monitor Impacting Bird Spikes

The wind direction is flatlining and wind speed occasionally does not compare well with 
co-located ECOR.  Problems with the height of the mount caused the vane to impact the bird 
deterrent spikes and "catch".  Symptoms appear as winds coming out of a 255 to 270 
direction for long period of times.  The wind speed values are also affected as the wind 
monitor is no longer normal to the wind direction.

SGP/SMOS/E3 - Rainfall Data Suspect

Rainfall during this time period was suspect as the gauge was found plugged on 07/12/2006. 
 Last check of site occurred on 06/28/2006.  Any rainfall data collected, whether the 
data is 0 or other than zero is suspect.

SGP/SMOS/E3 - Incorrect Offset for Wind Directon

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.
