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.

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.

  • Heat flux, sensible, best estimate(hcomb)
