Subject: | SGP/SWATS/E10 - Reprocess: Changed Depth Dimension |
DataStreams: | sgpswatsE10.b1 |
Description: | The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been changed. Newer files with the correct smaller depth dimension do not have extra placeholder values and thus are smaller in size. |

Subject: | SGP/SWATS/E10 - Incorrect soil moisture |
DataStreams: | sgpswatsE10.b1 |
Description: | All temperature rise values were incorrect. Soil moisture variables were also incorrect due to the incorrect T-rise values. Soil temperature measurements were not affected. |

DataStreams: | sgpswatsE16.b1 |
Description: | Sensors for all levels in both profiles were reporting values of temperature rise at or near 0 C. The incorrect values of temperature rise result in incorrect soil moisture data. |

Subject: | SGP/SWATS/E10 - Sensor failure, 15cm E |
DataStreams: | sgpswatsE10.b1 |
Description: | The 15cm E sensor failed at 7:00 GMT on 06/02/2002. Values of temperature rise from this sensor often do not fail automated QC tests, but inspection of the time series reveals that the values are incorrect. Since 2002, this sensor has alternated between providing temperature rise values near 0 C, equal to -9999, or other obviously incorrect values. Soil temperature data are not affected. |

Subject: | SGP/SWATS/E10 - Soil temperature irregular, 25cm W |
DataStreams: | sgpswatsE10.b1 |
Description: | The 25 cm W sensor was demonstrating temporal irregularities and were noisy at times. These irregularities consisted of dips and increases of around 2-4 C that typically started around 14:00 or 15:00 GMT on most days. On other days the values appeared somewhat noisy throughout the day. In both cases, the temporal changes did not compare well with the other sensors installed at E10. A broken wire was repaired for 25cm W sensor. |

Subject: | SGP/SWATS/E16 - Sensor failure, 125cm E |
DataStreams: | sgpswatsE16.b1 |
Description: | Temperature rise values from the 125 cm E sensor began to intermittently drop out to values near 0 C starting at 4:00 GMT on 12/14 before permanently reporting values near 0 C at 20:00 GMT on 12/15. The incorrect values of temperature rise result in incorrect matric potential and water content data for these sensors. Soil temperature for this sensor is not affected. Sensor resumed working 20090425. |

Subject: | SGP/SWATS/E10 - Incorrect calibrations |
DataStreams: | sgpswatsE10.b1 |
Description: | After a power outage, an older version of the datalogger program was accidently installed on the SWATS, resulting in improperly calibrated soilwatpot and watcont values from all levels in both profiles for this time period. |
