Applying Fourier’s law of heat conduction, the flux of heat in the soil ( J) can be expressed as: J=-k\frac {dT} {dz} (6.4) where dT/dz is the gradient of … WebOverview. The HFP01SC, manufactured by Hukseflux, measures soil heat flux—typically for energy-balance or Bowen-ratio flux systems. It is intended for applications requiring the highest possible degree of measurement accuracy. The HFP01SC outputs a voltage signal that is proportional to the heat flux of the surrounding medium.
WebApr 21, 2016 · Decreased roughness lengths lead to less outgoing sensible heat, which becomes the dominant driver in local soil temperatures for these experiments. Following deforestation the outgoing sensible heat flux (Fig 16) decreases more than at the high latitudes, resulting in a higher retention of heat in the soils, and thus higher soil …
