Subject:	SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR Header
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.
Measurements:	sgp30baebbrE12.c1: cs2 cs1 cs4 cs3 cs5

Subject:	SGP/EBBR/E12 - Incorrect Times
DataStreams:	sgp30baebbrE12.c1
Description:	The ntpd server (time adjustment) stopped working on Feb. 19th at 22:12:16 GMT, and 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/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 ALL INSTRUMENTS - Icing Event
DataStreams:	sgp30baebbrE12.c1
Description:	An icing event (winter storm Cara) passed slowly through the area during this time frame. Instruments at the SGP may have been affected by ice accumulation.

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.
