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.

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/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. |

Subject: | SGP/SWATS/E15 - Incorrect soil moisture |
DataStreams: | sgpswatsE15.b1 |
Description: | At 20:00 GMT on 05/07/08, temperature rise data from ALL sensors on both profiles began reporting values of temperature change near 0 C. These incorrect values of temperature rise result in incorrect soil moisture data for all sensors. Soil temperature data are unaffected. |

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. |

Description: | The temperature rise readings from the 15-cm depth on the east profile were incorrect (0 or -9999) This also caused the matric potential and water content data for the 15-cm depth to be incorrect. Soil temperature data measurements also failed 20060502. No data from this sensor should be used at or beyond this date. |

DataStreams: | sgpswatsE20.b1 |
Description: | Following a period of missing values (-9999) from 08/05/05-08/17/05, sensors at several depths failed. Temperature rise values from the 60cm West and 85cm East profile sensors were very noisy after 08/17/05. These data, including matric potential and water content, were incorrect. Temperature rise values from the 85cm West and 125cm East profile sensors are reported as 0 after 08/17/05. Matric potential and water content data for these sensor were also incorrect. Soil temperatures for these depths were unaffected. Temperature rise and soil temperature measurements for the 60cm East and 125cm West profile sensors were reported as 0 or -9999 after 08/17/05. Matric potential and water content data for these sensors were also incorrect. |

Subject: | SGP/SWATS/E27 - Incorrect serial numbers |
DataStreams: | sgpswatsE27.b1 |
Description: | The wiring at E27 from the Campbell Scientific 229-L sensors is backwards. This issue impacts the following variables but does not impact data quality: serial_numbers_W, serial_numbers_E. All serial numbers stored in the serial_numbers_W variable apply to data stored in the trise_E and tsoil_E variables, and vice versa. Thus, the user should be aware that the trise_W, trise_E, tsoil_W, and tsoil_E variables actually contain data from the opposite profile. |
