Subject:
SGP/EBBR/E27 - Reprocess: Soil Heat Flow #5 Offscale, Surface Fluxes Incorrect
DataStreams:sgp15ebbrE27.b1, sgp30ebbrE27.b1
Description:
Soil Heat Flow #5 went offscale at times.

Latent and Sensible Heat Fluxes were incorrect when this occurred.
Suggestions: 
Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
using only soil sets 1, 2, 3, and 4, as follows:

ave_shf = (g1 + g2 + g3 + g4)/4

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

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.

  • Soil heat flow 5 (mV)(soil_heat_flow_5_mv)
