Abstract

The impact of subgrid-scale variability of land characteristics on land-surface energy fluxes was investigated with Patchy Land-Atmosphere Interactive Dynamics (PLAID), a land-surface scheme that represents the land surface as a mosaic of patches. Eleven different distributions of the five predominant characteristics of land-surface schemes (i.e. stomatal conductance, soil-surface wetness, leaf area index, surface roughness, and albedo) were considered. A total of 5 580 900 steady-state simulations was produced to thoroughly analyze this impact under a broad range of atmospheric conditions. The more skewed the distribution within the range of landsurface characteristics that is related nonlinearly to the energy fluxes, the larger the difference between the energy fluxes calculated with the distribution and the corresponding mean. -from Authors
