Calculating the surface temperature of the solid underlying surface by modified 'force-restore' method

Abstract

The calculation of rocky surface temperature encounters the problem of unrealistic results due to its large changes at the interface where the energy balance equation is applied. In order to avoid this, we have modified the 'force-restore' method into a self-consistent procedure for simultaneous determination of both surface and the deep ground temperature. The approach is applicable to any celestial body where external radiation can be represented by an arbitrary periodic function. The method is tested with Earth based infrared observation on lunar surface temperature and it showed a high level of accuracy and a rather fast convergence of procedure. © Springer-Verlag 2000.
