The role of surface geophysical characteristics (e.g., albedo, thermal admittance, Bowen ratio, emissivity) in the partitioning of energy at the complex and heterogeneous metropolitan earth-air interface has been evaluated through a unique application of Lettau's climatonomy theory. In contrast to the conventional approach that first specifies an inventory of 'appropriate' surface descriptors and then attempts to evaluate or interpret observed climatic features, the climatonomical methodology permits the determination of the surface descriptors on the basis of the observed diurnal response of the surface to the observed forcing function of available solar energy. Features of various land-use types (e.g., farmland, suburban residential, commercial) can then be evaluated in the context of the surface energy budget. For example, if the subsurface heat flux is treated by assuming the medium is a homogeneous conductor, then an effective thermal admittance is derived that satisfies the assumption and the observed diurnal response of surface temperature.
