| DataStreams: | sgpswatsE12.b1 |
| Description: | See below for details of reprocessing that was completed on 20150814. Original DQR category: 5 (Transparent - Does not affect quality). ----------------------------------------------------------- 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 Site Power Outage Due to Winter Storm |
| DataStreams: | sgpswatsE12.b1 |
| Description: | On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use. |
