SGP/EBBR/E4 - Reprocess: Soil Temperature Malfunction
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
During a single half hour on July 23, soil moisture probe #3
indicated a value that was below the acceptable minimum, for
unknown reasons.

The affected quantities are:
15 minute: r_sm3
30 minute: sm3, c_shf3, cs3, ces3, g3, ave_shf, e, h
Suggestions: 
Sensible, latent, and soil heat fluxes need to be recalculated using the
change in energy storage of probes 1, 2, 4, and 5 as follows:

ave_shf = (g1 + g2 + g4 + g5)/4
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf + q)
Measurements:sgp30ebbrE4.b1:
  • Change in energy storage 3, 0-5 cm soil layer(energy_storage_change_3)
  • Soil heat flow 3, corrected for soil moisture(corr_soil_heat_flow_3)
  • Soil heat capacity 3(soil_heat_capacity_3)
  • Soil moisture 3, gravimetric(soil_moisture_3)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Surface soil heat flux 3(surface_soil_heat_flux_3)
  • Surface sensible heat flux(sensible_heat_flux)
