Heat exchange between the atmosphere and the non-uniform underlying surface under nonstationary radiative heating: a model and measurements

Summary The influence of variations in time of the forcing radiation on the thermal evolution of the soil/atmosphere surface layer system and the possibility to derive thermal characteristics from an analysis of the simultaneous series of the forcing and the response is represented. The described method permits to estimate soil density and heat eddy diffusivity in air. The method is tested using experimental data of the radiative fluxes, the fluctuations of the surface temperature and the temperatures of air at several levels.
