SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header
DataStreams:sgp30baebbrE20.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:sgp30baebbrE20.c1:
  • cs4
  • cs5
  • cs2
  • cs3
  • cs1

Subject:
SGP/EBBR/E20 - Left Air Temperature Incorrect
DataStreams:sgp30baebbrE20.c1
Description:
The left air temperature, and therefore top and bottom air temperatures
were offscale or incorrect on occasion.  Bowen ratio, sensible heat flux, and latent heat 
flux were also incorrect during those times.

Inspection of the data is required to detect the incorrect periods.
Measurements:sgp30baebbrE20.c1:
  • Corrected sensible heat flux(h)
  • Heat flux, latent, best estimate(ecomb)
  • Heat flux, sensible, best estimate(hcomb)
  • tair_top
  • bowen
  • Heat flux, latent(e)
  • tair_bot
  • Heat flux, latent, aerodynamic(ale)
  • Heat flux, sensible, aerodynamic(ah)

SGP/EBBR/E13/E15/E20/E22/E26/E4/E7/E8/E9  - BA EBBR VAP Bulk Aerodynamics
DataStreams:sgp30baebbrE20.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.
Measurements:sgp30baebbrE20.c1:
  • austar
  • Heat flux, latent, best estimate(ecomb)
  • Heat flux, sensible, best estimate(hcomb)
  • Heat flux, latent, aerodynamic(ale)
  • Heat flux, sensible, aerodynamic(ah)
