| Subject: | SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR |
| DataStreams: | sgp30baebbrE12.c1 |
| Description: | The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the EBBR 30 minute netcdf header have been incorrect from the beginning of processing the data into netcdf files. The correct units are MJ/m^3/C. This does not affect the data quality. |

| Subject: | SGP/EBBR/E12 - BA EBBR VAP Bulk Aerodynamics |
| DataStreams: | sgp30baebbrE12.c1 |
| Description: | Fixed AEM and wind speed sensor heights were improperly used in the calculation of bulk aerodynamic sensible and latent heat fluxes instead of site specific heights. This resulted in either under-estimation or over-estimation of the sensible and latent heat fluxes. |

| Subject: | SGP Site Power Outage Due to Winter Storm |
| DataStreams: | sgp30baebbrE12.c1 |
| 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. |
