Subject: | SGP/SWATS/E7 - Sensor failure, 35cm E |
DataStreams: | sgpswatsE7.b1 |
Description: | The 35-cm East sensor had several problems before failing permanently in 2007: 20061208.2000-20070306.2000: temperature rise reported values of -9999, and soil temperature reported abnormally high temperature values. 20070813.1200-20070912.1300: all variables reported as -9999, including soil temperature. A very small number of soil temperature values were reported as unusually high temperature values after 09/10/07. 20070912.1300-20070915.1600: incorrect values of temperature rise reported (near 0 C), and soil temperature values incorrect and unusually high. 20071110.0000-20071115.2300: incorrect values of temperature rise reported near 0 C or unusually low. Values of soil temperature OK. 20071128.0000-->: Except for two very brief recoveries (on the order of a few days), all 35cm E variables are reported as -9999. |

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/E7 - Soil temperature irregular, 125cm E |
DataStreams: | sgpswatsE7.b1 |
Description: | The 125 cm E sensor was demonstrating temporal irregularities in its soil temperature measurements. 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 E7. A bad fiber optic cable was replaced. |

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. |

DataStreams: | sgpswatsE11.b1 |
Description: | All trise values from the 60 cm E sensor are incorrectly reporting near zero. This also causes the matric potential (soilwatpot_E) and water content (watcont_E) data to be incorrect at this depth. |
