Subject: | SGP/EBBR/E13 - Soil temperature #3 offscale |
DataStreams: | sgp30ebbrE13.b1 |
Description: | Soil Temp Sensor 3 data were missing or offscale due to a bad connection. H and LE were not normally affected, as the EBBR program "kicked" out the incorrect temperature measurements before calculating H and LE. |

Subject: | SGP/EBBR/E13 - Sensible and Latent Heat Fluxes Too Large, Net Radiation Too Large |
DataStreams: | sgp30ebbrE13.b1 |
Description: | The net radiometer top dome broke and water entered the dome. The water settled in the bottom dome and caused net radiation measurements to be too large. Sensible and latent heat fluxes are therefore calculated to be too large. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgp30ebbrE13.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. |
