Calibration and Field Test of Soil Heat Flux Plates

Soil Science Society of America Journal, 1968
Abstract Soil heat flux plates were calibrated in the laboratory in steady‐state conditions and checked in the field vs. the soil temperature gradient thermal conductivity measurements of heat flux density. Good agreement was obtained after correcting for the flux divergence in the layer of soil where the temperature gradient was ...

Correcting errors associated with soil heat flux measurements and estimating soil thermal properties from soil temperature and heat flux plate data

Agricultural and Forest Meteorology, 1992
Abstract This paper deals with some of the problems associated with measuring the soil heat flux at a semiarid and sparsely vegetated site on the Colorado short-grass steppe. A linear model of soil temperature and heat flux is used to show that errors in the measurements of soil heat flux by the combination method can occur whenever the mean time ...

Soil heat flux determination: a null-alignment method

Agricultural Meteorology, 1975
Abstract A new technique for computing soil heat flux was developed which is based on measurements of only temperature and moisture content of the upper 20 cm of soil. First, calorimetry is used to calculate an initial estimate of the soil heat flux from an initial estimate for the thermal conductivity at 20 cm.

Remote estimation of thermal inertia and soil heat flux for bare soil

Agricultural and Forest Meteorology, 2004
Abstract A method is presented which allows thermal inertia (the soil heat capacity times the square root of the soil thermal diffusivity, C h D h ), to be estimated remotely from micrometeorological observations. The method uses the drop in surface temperature, Ts, between sunset and sunrise, and the average night-time net ...
