Subject:
SGP/EBBR/E20 - Reprocess: Soil Heat Flow #3 Incorrect During Sensor Changeout
DataStreams:sgp30ebbrE20.b1
Description:
Soil heat flow #3 measurements were incorrect during it's replacement.

Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can 
be recalculated using the remaining good sets of soil sensors as follows:
    ave_shf = (g1 + g5)/2
    e = -(q + ave_shf)/(1 + bowen)
    h = -(q + e + ave_shf)

Note: during the time period referenced here, soil heat flow #4 and #2 were also
incorrect.  This quality information is documented in D020717.46, D020717.47 and
D020726.1.
Suggestions: 
Measurements:sgp30ebbrE20.b1:
  • Surface soil heat flux 3(surface_soil_heat_flux_3)
  • Soil heat flow 3, corrected for soil moisture(corr_soil_heat_flow_3)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Soil heat flow 3(soil_heat_flow_3)
  • Surface sensible heat flux(sensible_heat_flux)
