Parameterization of subsurface heating for soil and concrete using net radiation data
The variability of surface sensible heat flux depend strongly on the rate of heating of the underlying surfaces. The variability is expected to be large in urban areas where the surfaces are layered with a variety of man-made materials. Parameterization of the ground heat storage as a function of surface materials is presented based on analyses of the U.S. Environmental Protection Agency's Regional Air Pollution Study (RAPS) conducted in St. Louis, MO. Ground heat flux data are derived from observations of surface and subsurface temperatures for a soil layer and for concrete slabs resting on soil. Simple mathematical expressions giving the ratio of ground heat storage to net radiation as a function of time are presented.
