SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header
DataStreams:sgp30baebbrE15.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.

SGP/EBBR/E15 - Wind Speed Incorrect
DataStreams:sgp30baebbrE15.c1
Description:
The cups were broken off of the wind speed sensor by hail on 4/23/04. The cups were 
replaced on 4/27/04.  Wind speed measurements were near zero and incorrect during the indicated 
period.

SGP/EBBR/E13/E15/E20/E22/E26/E4/E7/E8/E9  - BA EBBR VAP Bulk Aerodynamics
DataStreams:sgp30baebbrE15.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.

SGP Site Power Outage Due to Winter Storm
DataStreams:sgp30baebbrE15.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.
