Theoretical values of daily atmospheric and soil thermal admittances

Effective daily atmospheric and soil thermal admittances were calculated using harmonic solutions to the one-dimensional heat transfer equation for a semi-infinite medium. The thermal properties of both media were assumed to be power functions of depth only and it was shown how to calculate the parameters in these functions. The admittances critically depended on the manner in which the thermal properties varied near the surface.
