Subject: | SGP/SMOS/E6 - 6-month Calibration Checks |
DataStreams: | sgp1440smosE6.b1, sgp1smosE6.b1, sgp30smosE6.b1 |
Description: | During the time periods specified, the SMOS.E6 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/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. |
