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.
