Subject:
SGP/EBBR/E20 - Soil Moisture #4 and Soil Temperature #4 Incorrect
DataStreams:sgp30ebbrE20.b1, sgp15ebbrE20.b1
Description:
Failures of a multiplexer channel and a J-panel channel caused soil temperature #4 and 
soil moisture #4 to spike and drift at times.  Replacement of the failed equipment solved 
the problem.
Suggestions: 
Use data from the other four soil sets.
Measurements:sgp30ebbrE20.b1:
  • Surface soil heat flux 4(surface_soil_heat_flux_4)
  • Soil heat flow 4, corrected for soil moisture(corr_soil_heat_flow_4)
  • Soil heat capacity 4(soil_heat_capacity_4)
  • Soil moisture 4, gravimetric(soil_moisture_4)
  • Surface latent heat flux(latent_heat_flux)
  • Change in energy storage 4, 0-5 cm soil layer(energy_storage_change_4)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Half hour averaged soil temperature 4(soil_temp_4)
  • Surface sensible heat flux(sensible_heat_flux)
