Subject:
SGP/EBBR/E20 - Reprocess: Soil Temperature #2 Incorrect
DataStreams:sgp30ebbrE20.b1
Description:
Soil Temperature #2 was incorrect, apparently
from am loose wire after replacement of the EBBR unit.
The indicated measurements that are calculated using 
soil temperature are also incorrect.

See the work-around below.
Suggestions: 
Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
using only soil sets 1, 3, 4, and 5, as follows:

ave_shf = (g1 + g3 + g4 + g5)/4

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 2, 0-5 cm soil layer(energy_storage_change_2)
  • Surface soil heat flux 2(surface_soil_heat_flux_2)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Surface sensible heat flux(sensible_heat_flux)
  • Soil temperature 2(soil_temp_2)
