Abstract Since most land surfaces are non-uniform on meteorological model scales, usually applied flux-profile relationships to obtain surface flux densities cannot be used. Therefore, some modellers assume that these relations are scale-invariant if the local bulk transfer parameters are replaced by effective parameters. This approach leads to wrong results for grid cells that contain subgrid areas that differ largely with respect to stability. Hence, in such cases, the surface energy balance needs to be solved for each subgrid area separately. Therefore, to obtain the correct flux densities in all situations, for each grid cell in the horizontal domain of meteorological models, subgrid areas that differ with respect to stability need to be identified.
