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/CO2FLX/C1 - downwelling longwave hemispheric irradiance incorrect

Downwelling longwave radiation measurements (variable "r_down_long_hemisp") are bad due to 
a wiring issue. Users should not use the downwelling longwave hemispheric irradiance 
during this period. The downwelling shortwave and longwave radiation at CF is also available 
from the Broadband Radiometer Station (BRS).

• Downwelling longwave hemispheric irradiance; t_rad corrected(r_down_long_hemisp)

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.
