Subject:	SGP/SMOS/E6 - E6 SMOS Wind Direction
DataStreams:	sgp1smosE6.a0, sgp30smosE6.a1
Description:	Wind Direction incorrect during this time period. The bracket used to mount the wind direction sensor broke (ice suspected) on the 9th of February. It was replaced during routine maintenance on the 16th of February. We do not know why the data did not recover until the 22nd.

Subject:	SGP/SMOS/E6 - E6 SMOS Wind Direction
DataStreams:	sgp1smosE6.a0, sgp30smosE6.a1
Description:	Wind Direction incorrect during this time period. We noticed the data was incorrect on the 28th of February. During routine maintenance on the 1st of March the technician checked the wind direction sensor and noted that it needed to be replaced (no spares on hand at the time). On the 15th of March the sensor was replaced.

Subject:	SGP/SMOS/E6 - Incorrect Offset for Wind Directon
DataStreams:	sgp1smosE6.b1, sgp30smosE6.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.
Measurements:	sgp30smosE6.b1: Wind speed, vector-averaged, at 10-m height, 30-min intervals(wspd_va) Unit Vector Wind Direction(wdir) sgp1smosE6.b1: Unit Vector Wind Direction(wdir) Wind speed, vector-averaged, at 10-m height, 30-min intervals(wspd_va)
