Subject: | SGP/SWATS/E4 - Incorrect soil moisture data |
DataStreams: | sgpswatsE4.b1 |
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). |

Subject: | SGP/SWATS/E4 - Sensor failures, 5cm and 15cm W |
DataStreams: | sgpswatsE4.b1 |
Description: | The temperature rise readings from the 15-cm depth on the west profile were incorrect from 20040212:1500 to 20040217:0800. This also caused the matric potential and water content data for the 15-cm depth to be incorrect. The temperature rise readings from the 5-cm depth on the west profile were incorrect from 20040217:2300 to 20040218:1900. This also caused the matric potential and water content data for the 5-cm depth to be incorrect. |

Subject: | SGP/SWATS/E12 - Time drift |
DataStreams: | sgpswatsE12.b1, sgpswatspcpE12.b1 |
Description: | The time synchronization server stopped working on Feb. 19th at 22:12:16 GMT. The clock was corrected by -5600.177269 seconds on March 10th at 22:47 GMT. The recorded times for observations are off by amounts ranging from 0 seconds on Feb. 19th to 5600 seconds on March 10th. |

Subject: | SGP/SWATS/E12 - Reprocess: Changed Depth Dimension |
DataStreams: | sgpswatsE12.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/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/E12 - Precip measurement failure |
DataStreams: | sgpswatspcpE12.b1 |
Description: | The tipping-bucket rain gauge was not functioning correctly. The rain gauge measured no meaningful precipitation after 6/3 and did not agree well with nearby Oklahoma mesonet site precipitation measurements. Rain gauge replaced 6/16. |
