SGP/SMOS/E27 - Incorrect Offset for Wind Directon

An incorrect offset of 7 degrees was added to 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.

WindCalc = wdir - 7degrees
   if WindCalc < 0
   then
   Windcorr = WindCalc + 360
   Else
   Windcorr = WindCalc
