Subject: | SGP/SMOS/E3 - 6-month Calibration Checks |
DataStreams: | sgp1440smosE3.b1, sgp1smosE3.b1, sgp30smosE3.b1 |
Description: | During the time periods specified, the SMOS.E3 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. |

DataStreams: | sgp1smosE3.b1, sgp30smosE3.b1 |
Description: | When the SGP.E3 SMOS tower was installed it was not aligned properly resulting in a 7 degree offset. On 3/9/05, the datalogger program was modified to correct for this offset. |

Subject: | SGP/SMOS/E3 - Rainfall Data Suspect |
DataStreams: | sgp1smosE3.b1, sgp30smosE3.b1 |
Description: | Rainfall during this time period was suspect as the gauge was found plugged on 07/12/2006. Last check of site occurred on 06/28/2006. Any rainfall data collected, whether the data is 0 or other than zero is suspect. |

DataStreams: | sgp1440smosE3.b1, sgp1smosE3.b1, sgp30smosE3.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. |

Subject: | SGP/SMOS/E3 - Incorrect Offset for Wind Directon |
DataStreams: | sgp1smosE3.b1, sgp30smosE3.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. |
