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. |

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. |
