Subject:	SGP/SMOS/E7 - 6-month Calibration Checks
DataStreams:	sgp1440smosE7.b1, sgp1smosE7.b1, sgp30smosE7.b1
Description:	During the time periods specified, the SMOS.E7 tower was lowered for 6-month Calibration Checks. During these times wind data are incorrect and temperature and humidity data may be incorrect. Note, exact times when tower was down or maintenance was being performed is sometimes unknown. Users should use the remaining data from these days with caution. Calibration results are available from the OMIS database at http://www.ops.sgp.arm.gov:591/smos6cal/default.htm To view all 6-month calibration reports leave the date time entry blank.

During these times wind data are incorrect and temperature and humidity data may be incorrect. Note, exact times when tower was down or maintenance was being performed is sometimes unknown. Users should use the remaining data from these days with caution.

Subject:	SGP/EBBR/E7 - Windspeed threshhold too high
DataStreams:	sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:	The wind speed sensor developed worn bearings and therefore too high a starting threshhold. The data user should compare the EBBR wind speed with the SMOS wind speed to detect periods when the EBBR wind speed threshhold caused poor data quality.
Measurements:	sgp5ebbrE7.b1: scalar wind speed(wind_s) vector wind speed(res_ws) sgp30ebbrE7.b1: vector wind speed(res_ws) scalar wind speed(wind_s) sgp15ebbrE7.b1: scalar wind speed(wind_s)

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.
Measurements:	sgp1440smosE7.b1: Time of Minimum Wind Speed(time_min_wspd) Minimum of Wind speed(min_wspd) sgp30smosE7.b1: Wind Speed (vector averaged)(wspd_va) Standard Deviation of Wind Speed(sd_wspd) Mean Wind Speed(wspd) sgp1smosE7.b1: Mean Wind Speed(wspd) Wind Speed (vector averaged)(wspd_va)

Subject:	SGP/EBBR/E9 - Net Radiation Incorrect
DataStreams:	sgp15ebbrE9.b1, sgp30ebbrE9.b1, sgp5ebbrE9.b1
Description:	There was water in the net radiometer. The net radiation data was incorrect.
Measurements:	sgp15ebbrE9.b1: Net radiation(mv_q) sgp5ebbrE9.b1: net radiation(q) sgp30ebbrE9.b1: latent heat flux(e) h(h) net radiation(q)

Subject:	SGP/SMOS/E9 - Wind Data Incorrect Due to Icing
DataStreams:	sgp1440smosE9.b1, sgp1smosE9.b1, sgp30smosE9.b1
Description:	An ice storm caused the wind data from the RM Young wind sensor to be incorrect. In many instances it was frozen and unmoving, at times it measured values but those are extremely suspect.
Measurements:	sgp30smosE9.b1: Wind Speed (vector averaged)(wspd_va) Mean Wind Speed(wspd) Unit Vector Wind Direction(wdir) Standard Deviation of wind direction(sd_deg) Standard Deviation of Wind Speed(sd_wspd) sgp1440smosE9.b1: Minimum of Wind speed(min_wspd) Time of Maximum Wind Speed(time_max_wspd) Time of Minimum Wind Speed(time_min_wspd) maximum wind speed (gusts)(max_wspd) sgp1smosE9.b1: Unit Vector Wind Direction(wdir) Standard Deviation of wind direction(sd_deg) Mean Wind Speed(wspd) Wind Speed (vector averaged)(wspd_va)

DataStreams:	sgp1440smosE7.b1, sgp1smosE7.b1, sgp30smosE7.b1
Description:	The wind data appear sluggish compared to nearby sites. Cold temperatures and precip suggest mild icing on the sensor.

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.
