Subject:
SGP/EBBR/E19 - Reprocess: Soil Heat Flow #3 Incorrect Calibration
DataStreams:sgp30ebbrE19.b1
Description:
Soil Heat Flow #3 was incorrect during these periods.

To use the measurements, multiply Soil Heat Flow #3 by 0.726.
  
See below for a work-around.
Suggestions: 
Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
as follows:

ave_shf = (g1 + g2 + ces3 + c_shf3*0.726 + g4 + g5)/5

e = -(q + ave_shf)/(1 + Bowen)

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.
Measurements:sgp30ebbrE19.b1:
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Soil heat flow 3(soil_heat_flow_3)
  • Surface sensible heat flux(sensible_heat_flux)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux 3(surface_soil_heat_flux_3)
  • Soil heat flow 3, corrected for soil moisture(corr_soil_heat_flow_3)
