Subject:	SGP/SMOS/E7 - Rainfall Data Suspect
DataStreams:	sgp1smosE7.b1, sgp30smosE7.b1
Description:	Rainfall during this time period was suspect as the gauge was found plugged on 11/28/2006. Last check of site occurred on 11/14/2006. Any rainfall data collected, whether the data is 0 or other than zero is suspect.

Subject:	SGP/SMOS/E7 - Wind sensor binding at low wind speeds
DataStreams:	sgp1440smosE7.b1, sgp1smosE7.b1, sgp30smosE7.b1
Description:	The wind sensor bearings were failing causing the wind speed sensor to report lower than actual wind speeds when the winds were below 2 m/s. The wind monitor was replaced on 05/29/2007 but this failed to correct the problem. Subsequently, the site was flooded and it took some time to re-establish normal operations. The wind sensor was again replaced on 10/30/2007. After replacement the wind data from the SMOS compared more favorably to the co-located EBBR data.

Subject:	SGP/SMOS/E7 - Incorrect Offset for Wind Directon
DataStreams:	sgp1smosE7.b1, sgp30smosE7.b1
Description:	An incorrect offset of 6 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.
