SGP/EBBR/E19 - Reprocess: E19 EBBR Soil heat Flow Probe #5 Upsidedown
DataStreams:sgp30ebbrE19.b1, sgp15ebbrE19.b1
Description:
Soil heat flow probe #5 was installed upsidedown at the initial
installation of the EBBR system.  The data from it had the wrong sign.
Site operations personnel reversed its orientation in the soil on August
14, 1997, thereby correcting the problem.

Values affected (and thus incorrect) include:

15 minute: mv_hft5
30 minute: shf5, c_shf5, g5, ave_shf, e, h.

The latent and sensible heat fluxes can be recalculated by reversing the
sign of cshf5, adding it to ces5 and recomputing the average soil heat flow,

ave_shf = (g1 + g2 + g3 + g4 + g5)/5

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

h = -(e + ave_shf + q).
Suggestions: 
Measurements:sgp30ebbrE19.b1:
  • Soil heat flow 5, corrected for soil moisture(corr_soil_heat_flow_5)
  • Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
  • Soil heat flow 5(soil_heat_flow_5)
  • Surface sensible heat flux(sensible_heat_flux)
  • Surface latent heat flux(latent_heat_flux)
  • Surface soil heat flux 5(surface_soil_heat_flux_5)
