Subject:
SGP/EBBR/E13 - Reprocess: E13 EBBR Soil heat Flows #1 and #2 Incorrect
DataStreams:sgp30ebbrE13.b1, sgp15ebbrE13.b1
Description:
Soil Heat Flow probes #1 and #2 were incorrect during the
indicated period (and for some time afterward, to be covered in another
DQR).  Outputs from the probes were typically too large negative or 
too large positive.
Suggestions: 
The soil, sensible and latent heat fluxes can be recalculated using the
information from the three good soil sets and the equations below.

ave_shf = (g3 + g4 + g5)/3

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

h = -(ave_shf + q + e)
Measurements:sgp15ebbrE13.b1:
  • Soil heat flow 1 (mV)(soil_heat_flow_1_mv)
  • Soil heat flow 2 (mV)(soil_heat_flow_2_mv)
