Partition of sensible heat fluxes into bare soil and the atmosphere
Agricultural and Forest Meteorology, 1996Energy exchanges between a bare soil and the atmosphere depend on both soil parameters and meteorological conditions. The present work has been designed to describe the sensible heat partition between soil and the atmosphere, and to develop simple methods for calculating soil heat flux from soil properties and meteorological data.

Estimation of soil heat flux by apparent thermal inertia
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011By analyzing the relationship between midday soil heat flux (G m ) and apparent thermal inertia (ATI) by time series observations from YuCheng agroecological station, CAS, a method of estimating midday G by ATI was presented in the paper. ATI method is shown to have the close agreement with the observations.

Modified heat-meter method for determining soil heat flux
Agricultural and Forest Meteorology, 1990Abstract The theory of heat-flux meters describing the perturbation of a uniform, steady heat flux through a porous medium (soil) by a meter of different thermal conductivity was tested and confirmed under laboratory conditions. From the theory, an equation was derived for determining the heat flux density through the medium which is more accurate ...

Impacts of Surface Fluxes on Interseasonal Heat Storage in Soils
Proceedings, 2013This paper presents a three-dimensional model that couples both soil mass and storage system behaviour. The proposed model is applied to consider a field application case study, with particular focus on the correct representation of the surface flux and its impact on ground energy storage.

Determination of the mean soil temperature for evaluation of heat flux in soil
Agricultural Meteorology, 1983Abstract A technique for determining surface soil heat flux, based upon measurements of the mean temperature, T , and upon knowledge of the mean moisture content of the soil, is described. A thermocouple probe was developed to measure the mean soil temperature, T , of the upper 50 cm of a soil.

Energy conversions on the soil surface and the temperature conditions that result from them in the ground-proximate air only become entirely clear when one knows more concerning the heat movement in soil and in the air. In order to understand heat movement in the soil, one first needs to know something concerning the physical properties of soils. Every

An apparatus for calibrating soil heat flux plates
Agricultural Meteorology, 1977Abstract The design and construction of an apparatus for calibrating soil heat flux plates is described. The apparatus produces a known constant heat flux through a layer of an appropriate porous medium contained in a small, well-insulated box. A secondary heater, positioned below the primary heater, operates automatically to ensure that all the heat

The measurement and recording of the heat flux into the soil
Quarterly Journal of the Royal Meteorological Society, 1950AbstractRelatively simple instruments for measuring the heat flux into or out of the soil are described together with methods of calibration. One form consists of a suitable metal disc of sandwich construction producing a thermal e.m.f. proportional to the heat flux through the disc, which is placed in the soil just below the surface.Details are also ...

Journal of Agronomy and Crop Science, 1988
AbstractA simple approach was undertaken to estimating bare soil evaporation in a soil column in a laboratory. The measurement of soil heat flux and soil water flux at various depths provides a practical means of assessing and evaluating the position of the drying front (evaporation zone) in the soil.

Soil Surface Roughness Effects on Radiation Reflectance and Soil Heat Flux
Soil Science Society of America Journal, 1987Abstract Soil surface roughness provides a mechanism to alter soil reflectance and the surface energy balance. A field study was conducted to determine the effect of surface roughness on energy absorption and energy partitioning at the soil surface.
