SGP/EBBR/E27 - Most Measurements Suspect

The wrong EBBR program was used at this site.  Therefore, most of the measurements are 
suspect.

Note: Mentor reports reprocessing will not correct this problem.

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.
