Subject: | SGP/SWATS/E5 - Sensor failure, 25cm E |
DataStreams: | sgpswatsE5.b1 |
Description: | The temperature rise readings from the 25-cm depth on the east profile are incorrect. This also causes the matric potential and water content data to be incorrect. |

DataStreams: | sgpswatsE5.b1 |
Description: | The 25-cm East sensor began reporting missing values (-9999) after 0130 GMT, with intermittent incorrect values. All data from this sensor are missing or incorrect. Instrument removed from service 20091102. |

Subject: | SGP/SWATS/E13 - Reprocess: Changed Depth Dimension |
DataStreams: | sgpswatsE13.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/E5 - Incorrect soil moisture data |
DataStreams: | sgpswatsE5.b1 |
Description: | The temperature rise values were too high (> 20 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 T_rise is too high, the soil moisture data is dubious at best and unusable at worst. Soil temperatures are OK. |

Subject: | SGP/SWATS/E5 - Sensor failure, 5cm E |
DataStreams: | sgpswatsE5.b1 |
Description: | The temperature rise on 5cm E profile are incorrect (> MAX QC test) beginning 20070623. This also causes the matric potential and water content data to be incorrect. |

Subject: | SGP/SWATS/E5 - Sensor failure, 15cm W |
DataStreams: | sgpswatsE5.b1 |
Description: | Both the temperature rise and soil temperature for the 15-cm W profile began to intermittently report as -9999 on 04/08/08. The intermittent drop outs continued until 9:00 GMT on 04/20/08 after which all data are reported as -9999 through the current date. This problem also impacts the matric potential and water content data. Instrument removed from service 20091102. |

Subject: | SGP/SWATS/E5 - Sensor failure, 125cm W |
DataStreams: | sgpswatsE5.b1 |
Description: | Both the temperature rise and soil temperature measures of the 125-cm W profile are reported as -9999 since 10/07/99. This sensor has been essentially dead since then, and all associated variables are impacted. Instrument removed from service 20091102. |

Subject: | SGP/SWATS/E5 - Sensor failure, 175cm W |
DataStreams: | sgpswatsE5.b1 |
Description: | The temperature rise of the 175cm W profile began reporting as incorrect with values near 0 C on 20010817. This also causes the matric potential and water content data to be incorrect. Soil temperature data are not affected. Instrument removed from service 20091102. |

Subject: | SGP/SWATS/E5 - Sensor failure, 175cm E |
DataStreams: | sgpswatsE5.b1 |
Description: | The temperature rise of the 175-cm East profile began reporting as incorrect with values near 0 C. This also caused the matric potential and water content data to be incorrect. On 10/28/08, a broken wire was fixed and data came back online. Soil temperature data was unaffected. |

Subject: | SGP/SWATS/E13 - Lightning damage |
DataStreams: | sgpswatsE13.b1 |
Description: | After a lightning strike near the CF, the SWATS trise values were reporting near zero. The current channel in the CE8 module failed, so the wire was moved to the next channel and trise values returned to normal. There are no soil moisture data available during this time period. |
