Subject:
SGP/EBBR/E2 - Soil Heat Flow #1 Incorrect
DataStreams:sgp30ebbrE2.b1, sgp15ebbrE2.b1
Description:
Soil Heat Flow #1 was very large most of the period.

See below for a work-around.
Suggestions: 
Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
using only soil sets 2, 3, 4, and 5, as follows:

ave_shf = (g2 + g3 + g4 + g5)/4

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

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.
Measurements:sgp30ebbrE2.b1:
  • Surface soil heat flux 1(surface_soil_heat_flux_1)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Surface sensible heat flux(sensible_heat_flux)
  • Soil heat flow 1(soil_heat_flow_1)
  • Soil heat flow 1, corrected for soil moisture(corr_soil_heat_flow_1)
