Subject:
SGP/EBBR/E9 - Sensible and latent heat flux sometimes incorrect
DataStreams:sgp30ebbrE9.b1
Description:
Soil temperature 3 was usually several degrees lower than the other four soil temperature 
measurements and usually did not follow a diurnal trend.

Soil moisture 3 was usually ten to thirty percent higher than the other four soil moisture 
measurements and usually did not follow a diurnal trend.

Avoid derived latent and sensible heat fluxes at times when the soil_temp_3 deviates from 
the other soil_temp_[1,2,4] by more than 1 C, or the soil_moisture_3 deviates from the 
other soil_moisture_[1,2,4] by more than 10%.
Suggestions: 
Measurements:sgp30ebbrE9.b1:
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Soil heat capacity 3(soil_heat_capacity_3)
  • Soil heat flow 3, corrected for soil moisture(corr_soil_heat_flow_3)
  • Soil heat flow 3(soil_heat_flow_3)
  • Soil moisture 3, gravimetric(soil_moisture_3)
  • Surface sensible heat flux(sensible_heat_flux)
  • Surface soil heat flux 3(surface_soil_heat_flux_3)
  • Soil temperature mean 3(soil_temp_3)
