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/E8 - AEM Replacement
DataStreams:sgp15ebbrE8.b1, sgp30baebbrE8.c1, sgp30ebbrE8.b1, sgp5ebbrE8.b1
Description:
The AEM at E8 kept hanging in between home positions.

This DQR covers only the period during which the AEM was being
replaced.  

DQRs generally are not issued for AEMs that are not working
as qc flags indicate this clearly.

SGP/EBBR/E13/E15/E20/E22/E26/E4/E7/E8/E9  - BA EBBR VAP Bulk Aerodynamics
DataStreams:sgp30baebbrE13.c1, sgp30baebbrE15.c1, sgp30baebbrE20.c1, sgp30baebbrE22.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.
