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. |

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. |

Subject: | SGP/ECOR/E5 - Reprocess: Time shifted -7 hours |
DataStreams: | sgp30ecorE5.b1, sgpecorE5.00 |
Description: | An inadvertant power outage caused the ECOR program to shut down abnormally. When power was restored, the timestamps on the ECOR files were 7 hours behind the correct time and the site ID was not accessed from the ECOR configuration file resulting in site ID (05) being replaced with "AN". These conditions caused the ECOR files to be unrecognizable and therefore are presently missing in the Archive. Correction of the timestamp and ID in the files should allow them to be processed and added to the Archive. |

Subject: | SGP/ECOR/E21 - Intermittent incorrect flux measurements |
DataStreams: | sgp30ecorE21.b1 |
Description: | At various times during the period, the LI-7500 CO2/H2O serial and analog signals from the LI-7500 were missing, but usually not at the same time. When the CO2/H2O serial datastream was missing, the Pressure and Temperature were missing; this did not, in itself, result in incorrect fluxes, as default values for pressure and temperature are automatically used. Fluxes were incorrect when the CO2/H2O analog datastream was missing; these times are identified by the qc checks. |

Subject: | SGP/ECOR/E5 - Flux Measurements Incorrect |
DataStreams: | sgp30ecorE5.b1 |
Description: | The ECOR datastream was corrupted; this happens when the ECOR program produces a datastream of the wrong length (i.e., leaves one or more measurements out). Fluxes and some other measurements are incorrect. Note: Mentor reports reprocessing will not correct this problem. |

DataStreams: | sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1 |
Description: | The wind direction sensor reported wind directions that were 65 degrees too low because of a mis-alignment. This bias should have no effect on the res_ws or sigma_wd measurements. The wind direction data could be re-processed by adding 65 degrees. |

Subject: | SGP/ECOR/E24 - Water Vapor Density Incorrect |
DataStreams: | sgp30ecorE24.b1 |
Description: | Mean Water Vapor Density (mean_q) often did not trend well with the co-located SMOS and sometimes jumped downwards approximately 200 to 300 mmol/m^3. Some of the instances were clearly a result of contamination by precipitation, but others were not; the latent heat flux was sometimes affected. It was determined that all instances of this behavior from the beginning of 2008 through the beginning date of this DQR were caused by precipitation/dew/frost. |
