DataStreams: | sgp1440smosE8.b1, sgp1smosE8.b1, sgp30smosE8.b1 |
Description: | During the time periods specified, the SMOS.E8 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/SIRS/C1 - SWFANAL Data description error |
DataStreams: | sgp15swfanalsirs1longC1.c1, sgp1swfanalsirs1longC1.c1 |
Description: | The long name attribute for the cloud effect fields incorrectly defines the cloud effect to be the difference between the clearskyfit and measured values: "Difference: ***fluxdn_clearskyfit - ***fluxdn_measured (***fcg)" ; The cloud effects are correctly calculated by subtracting the irradiance calculated in the clear sky fit from the measured irradiance. "Difference: ***fluxdn_measured - ***fluxdn_clearskyfit (***fcg)" ; NOTE: this is just a documentation error. The data are correctly calculated. |

DataStreams: | sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1 |
Description: | The flux and gradient measurements were often incorrect when the AEM did not function properly. The user needs to inspect the data (particularly the home signals) to determine when the AEM was and was not working. |

DataStreams: | sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1 |
Description: | The left humidity sensor produced large spikes frequently. This resulted in incorrect measurements of vapor pressure gradient and thus calculations of sensible and latent heat flux. |

DataStreams: | sgp15ebbrE8.b1, sgp30ebbrE8.b1, sgp5ebbrE8.b1 |
Description: | The right Temperature-Humidity sensor failed. The measured temperature gradients were incorrect and thus the sensible and latent heat fluxes were incorrect for this extended period. The sensor was replaced March 6. |

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. |
