Subject:
SGP/EBBR/E20 - Reprocess: Soil Temperature #3 Incorrect
DataStreams:sgp30ebbrE20.b1
Description:
Soil Temperature #3 was incorrect.
The cause is apparently vandalism; the probe leads were cut. 
The indicated measurements that are calculated using soil 
temperature are also incorrect.

DQR D030117.19 already provides the work-around for
calculating correct sensible (h) and latent heat (e) fluxes,
as soil heat flow #3 and soil heat flow #5 were also incorrect
during this period.  That work-around is repeated below.
Suggestions: 
Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
using only soil sets 1, 2, and 4, as follows:

ave_shf = (g1 + g2 + g4)/3

e = -(q + ave_shf)/(1 + Bowen)

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.
Measurements:sgp30ebbrE20.b1:
  • Change in energy storage 3, 0-5 cm soil layer(energy_storage_change_3)
  • Surface soil heat flux 3(surface_soil_heat_flux_3)
  • Surface latent heat flux(latent_heat_flux)
  • Soil temperature mean 3(soil_temp_3)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Surface sensible heat flux(sensible_heat_flux)
