SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header
DataStreams:sgp30baebbrE18.c1, sgp30baebbrE19.c1, sgp30baebbrE2.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.

(NOTE: The actual begin date of some of these data
streams is as early as 5/22/97.  This DQR applies to
all 30m EBBR data.)
Measurements:sgp30baebbrE2.c1:
  • Soil heat capacity 5(cs5)
  • Soil heat capacity 2(cs2)
  • Soil heat capacity 1(cs1)
  • Soil heat capacity 3(cs3)
  • Soil heat capacity 4(cs4)
sgp30baebbrE19.c1:
  • Soil heat capacity 5(cs5)
  • Soil heat capacity 2(cs2)
  • Soil heat capacity 3(cs3)
  • Soil heat capacity 4(cs4)
  • Soil heat capacity 1(cs1)

briefly, then sat at the home 15 position until another 
replacement was available.

SGP/EBBR/E18 - BA EBBR VAP Bulk Aerodynamics
DataStreams:sgp30baebbrE18.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:sgp30baebbrE18.c1:
  • Friction velocity(austar)
  • Best estimate Latent heat flux(ecomb)
  • Aerodynamic Sensible heat flux(ah)
  • Aerodynamic Latent heat flux(ale)
  • Best estimate Sensible heat flux(hcomb)
