SGP/EBBR/E8 - Reprocess: SHF2 Incorrect

Soil heat flow probe #2 outputted incorrect, large positive values during the
period indicated.  Replacement of the probe on 29 October 1997 corrected the
problem.  The serial number of the probe replaced is 923025 and of the
replacement probe is 923110.

The data affected (and thus incorrect) includes:

15 minute: mv_hft2
30 minute: shf2, c_shf2, g2, ave_shf, e, h.

The latent and sensible heat fluxes can be recalculated by using only soil
heat flows 1, and 3 through 5 to calculate the average soil heat flow,

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

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

h = -(e + ave_shf + q)

Recalculate average soil heat flow (ave_shf) and latent (e) and 
sensible(h) heat fluxes with the equations provided.

• Soil heat flow 2 (mV)(soil_heat_flow_2_mv)

• Surface latent heat flux(latent_heat_flux)
• Surface soil heat flux 2(surface_soil_heat_flux_2)
• Surface sensible heat flux(sensible_heat_flux)
• Soil heat flow 2, corrected for soil moisture(corr_soil_heat_flow_2)
• Soil heat flow 2(soil_heat_flow_2)
• Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
