Subject:	SGP/SMOS/E4 - Incorrect Offset for Wind Directon
DataStreams:	sgp1smosE4.b1, sgp30smosE4.b1
Description:	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.
