Subject: | SGP/SWATS/E12 - Incorrect soil moisture |
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. Soil temperature measurements were not affected. |

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. |
