SGP/EBBR/E2 - Reprocess: E2 Soil Heat Flow #4 Incorrect - Replaced
DataStreams:sgp30ebbrE2.b1, sgp15ebbrE2.b1
Description:
Soil heat flow probe #4 produced intermittently large positive
and negative values from October 1997 until 3 January 1998, after
which the values remained high until the probe was replaced on
8 January 1998 at 1711 GMT.

The following data values were affected for the period listed
above (when soil heat flow #4 was large):

15 minute: mv_hft4
30 minute: shf4, c_shf4, g4, ave_shf, e, h
Suggestions: 
The latent and sensible heat fluxes can be recalculated by using only soil
heat flows 1, 2, 3, and 5 to calculate the average soil heat flow,

ave_shf = (g1 + g2 + g3 + g5)/4

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

h = -e + ave_shf + q).
Measurements:sgp30ebbrE2.b1:
  • Surface latent heat flux(latent_heat_flux)
  • Soil heat flow 4(soil_heat_flow_4)
  • Surface sensible heat flux(sensible_heat_flux)
  • Soil heat flow 4, corrected for soil moisture(corr_soil_heat_flow_4)
  • Surface soil heat flux 4(surface_soil_heat_flux_4)
