Description: | The temperature rise readings on both the east and west profiles are too high. This also causes the matric potential and water content data to be incorrect. For the first, third and fourth date ranges, measurements are incorrect for all sensor locations (each depth on both profiles). For the second date range, measurements are incorrect for the lowest 8 sensor locations (the 60cm, 85cm, 125cm, and 175cm depths on both profiles). |

DataStreams: | sgpswatsE12.b1 |
Description: | Temperature rise values were way to high (~40 deg C). Water potential is calculated from a rise (and subsequent drop) in temperature in the sensor that is normally ~1-5 degrees C. When the temperature rise is too high, the soil moisture data is dubious at best and unusable at worst. Since this "out-of-bounds" t_rise is so high, the soil moisture data are practically unusable.

DataStreams: | sgpswatsE24.b1 |
Description: | The Cyril EF is located on a gypsum outcropping overlooking a wheat field. When the SWATS was installed, it was placed in a "hole" in the gypsum filled with soil. The IM does not believe that this is conducive to collection of data that would be representative of local soil moisture conditions due to this arrangement. While the soil temperature and moisture data are correct for the conditions in that spot, it is very likely that the gypsum surroundings create an environment that would be unlike the surrounding area, and should be aware that the data may not be representative of actual mean local conditions. |

Description: | Both trise and tsoil for the 5cm E sensor began to drop out intermittently reporting both incorrect values and values of -9999 starting on 08/18/2007. Since this date, there have been periods where values of -9999 have been reported continuously for months at a time, but the sensor always seems to come back eventually and report values that appear correct. Currently, this sensor is reporting normal values again but has failed as recently as 10/08/08. When this sensor is failing, it typically impacts tsoil_E, trise_E, soilwatpot_E, and watcont_E. However, there are cases where tsoil_E appears OK while the other variables are incorrect. Instrument was removed from service 20091014. |

Subject: | SGP/SWATS/E8 - Sensor failure, 35cm W |
DataStreams: | sgpswatsE8.b1 |
Description: | The sensor installed at 35 cm at the west profile has produced questionable data ince it was installed back in 1996. Once the sensor began to stabilize at 17:00 GMT on 07/20/99, it has produced questionable or incorrect values of temperature rise. From 07/20/99 to the present date, 35cm W temperature rise values have stayed within a range of approximately 0.8-2.0 C, while the sensor from the 35cm E profile has produced an approximate range of 1.5-4.0 C. In addition, the calibration for this sensor is so bad it is not possible to correct it using field data. The range of temperature rise values produced by this sensor is too limited to reliably re-calibrate the instrument. Under the old ARM calibration for SWATS, the calibrated reference temperature change should fall within a range of 1.45-4.00 C (the new range is 1.38-3.96 C). For this sensor, the reference temperature change has fallen within an approximate range of 0.2-1.7 C and the calibration is actually adjusting the trise measurements in the wrong direction. Therefore, all temperature rise, matric potential and water content data are all highly suspect from the 35cm W sensor. The soil temperature data appear to be OK. Instrument removed from service 20091110. |

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/E1 - Instrument failure |
DataStreams: | sgpswatsE1.b1 |
Description: | The diurnal temperature change in the tsoil measurements from all sensors installed below 5 cm at this facility appear questionable. On a daily basis, the diurnal trends in the tsoil measurements from depths below 5 cm did not match the above ground tref measurements or the tsoil measurements from the 5 cm W sensor (the 5 cm E sensor has failed). The tsoil measurements from these deeper sensors began to decrease prior to solar noon nearly every day. Also, the magnitudes of the diurnal change in these instruments appear to be the same for all sensors (Normally, the diurnal changes in tsoil are damped as we progress deeper below the surface). Attempts to correct the problem were unsuccessful until the time of site decommissioning. This facility was decommissioned and maintenance efforts ceased 10/1/2009. |
