Subject:
SGP/EBBR/E9 - Reprocess: Soil Temperature #5 Incorrect
DataStreams:sgp30ebbrE9.b1
Description:
Soil Temperature #5 was intermittently incorrect.
The cause is unknown. The indicated measurements 
that are calculated using soil temperature 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 1, 2, 3, and 4, as follows:

ave_shf = (g1 + g3 + g3 + g4)/4

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

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.
Measurements:sgp30ebbrE9.b1:
  • Surface latent heat flux(latent_heat_flux)
  • Half hour averaged soil temperature 5(soil_temp_5)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Surface soil heat flux 5(surface_soil_heat_flux_5)
  • Surface sensible heat flux(sensible_heat_flux)
  • Change in energy storage 5, 0-5 cm soil layer(energy_storage_change_5)
