Subject:
SGP/EBBR/E4 - Reprocess: Soil Temperature Malfunction
DataStreams:sgp30ebbrE4.b1, sgp15ebbrE4.b1
Description:
During individual half hours on three days, soil moisture probe #1 
indicated values that were below the acceptable minimum, for unknown
reasons.

The times of incorrect data and the affected quantities are shown below.

SM1:     Half Hour     15 Minute
20 July: 1800 GMT    1745, 1800 GMT
21 July: 0800 GMT    0745, 0800 GMT
22 July: 1800 GMT    1745, 1800 GMT

15 minute: r_sm1
30 minute: sm1, c_shf1, cs1, ces1, g1, ave_shf, e, h
Suggestions: 
Sensible, latent, and soil heat fluxes need to be recalculated using the
change in energy storage of probes 2-5 as follows:

ave_shf = (g2 + g3 + g4 + g5)/4
e = -(q + ave_shf)/(1 + bowen)
h = -(e + ave_shf + q)
Measurements:sgp30ebbrE4.b1:
  • Change in energy storage 1, 0-5 cm soil layer(energy_storage_change_1)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Soil moisture 1, gravimetric(soil_moisture_1)
  • Soil heat capacity 1(soil_heat_capacity_1)
  • Surface sensible heat flux(sensible_heat_flux)
  • Surface soil heat flux 1(surface_soil_heat_flux_1)
  • Soil heat flow 1, corrected for soil moisture(corr_soil_heat_flow_1)
