Subject:
SGP/EBBR/E20 - Reprocess: Soil Temperature #1 and Soil Heat Flow #5 Incorrect
DataStreams:sgp30ebbrE20.b1
Description:
Soil Temperature #1 and Soil Heat Flow #5 were incorrect
during these periods. The indicated calculated measurements
are also incorrect.
Suggestions: 
Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h)
using only soil sets 2, 3, and 4 as follows:

ave_shf = (g2 + g3 + g4)/3
e = -(q + ave_shf)/(1 + Bowen)
h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.
Measurements:sgp30ebbrE20.b1:
  • Change in energy storage 1, 0-5 cm soil layer(energy_storage_change_1)
  • Surface soil heat flux 1(surface_soil_heat_flux_1)
  • Surface latent heat flux(latent_heat_flux)
  • Soil heat flow 5, corrected for soil moisture(corr_soil_heat_flow_5)
  • Surface soil heat flux 5(surface_soil_heat_flux_5)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Soil heat flow 5(soil_heat_flow_5)
  • Surface sensible heat flux(sensible_heat_flux)
  • Soil temperature 1(soil_temp_1)
