Subject: | SGP/SWATS/E20 - Incorrect Soil Moisture Data |
DataStreams: | sgpswatsE20.00, sgpswatsE20.b1 |
Description: | Due to failure of an electronic component (apparently caused by the onset of precipitation), the temperature rise readings from both the west and east profiles (trise_W, trise_E) are incorrect at all depths. This also causes the matric potential (soilwatpot_W, soilwatpot_E) and water content (watcont_W, watcont_E) data to be incorrect. |

Subject: | SGP/SWATS/E20 - Reprocess: Changed Depth Dimension |
DataStreams: | sgpswatsE20.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/E20 - Sensor failure, 5cm E |
DataStreams: | sgpswatsE20.b1 |
Description: | The temperature rise readings from the 5-cm depth on the east profile are incorrect. This also causes the matric potential and water content data for the 5-cm depth to be incorrect. The soil temperature measurements were not affected. |

Subject: | SGP/SWATS/E20 - Sensor failure, 15cm E |
DataStreams: | sgpswatsE20.b1 |
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. |

Subject: | SGP/SWATS/E20 - Sensor failures |
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/E20 - Incorrect soil moisture data |
DataStreams: | sgpswatsE20.b1 |
Description: | After 12/20/2007, temperature rise values for all sensors (still operational at the time) were much too high, on the order of 10's of degrees C. Matric potential and water content data for these sensors were also incorrect. |

DataStreams: | sgpswatsE20.b1 |
Description: | The East 25 cm sensor t-rise values dropped to zero on 7/11. The t-rise values came back up on 7/22 0200 GMT, but again were missing from 7/25 1600 GMT through 7/27 1700 GMT. Ops reseated connection. |
