“…Canopy cover is an important parameter in a variety of land-surface biophysical and biogeochemical models sensitive to landscape heterogeneity [e.g., Running et al, 1994;Bonan, 1995]. Numerous studies have demonstrated the strong effect of surface heterogeneity on factors such as hydrology [Ghan et al, 1997], roughness length [Oleson et al, 2000], and albedo [Rowe, 1993] which are important for land-atmosphere interactions. For example, Yang et al [1999] showed that the areal coverage of vegetation strongly affects ground heat flux calculations critical to atmospheric models.…”

“…Therefore, representations of subgrid land surface heterogeneity are still needed and employed in many land surface models. It has been well established that subgrid spatial variability in land surface characteristics such as vegetation cover and topography can significantly affect the estimation of surface evapotranspiration, runoff, soil moisture, surface albedo, snowpack, and other fluxes (Koster and Suarez, 1992;Seth et al, 1994;Giorgi and Avissar, 1997;Ghan et al, 1997;Li and Arora, 2012;Li et al, 2013).…”

“…This situation approximates the treatment the study area could receive as one grid cell in a general circulation model. Global change studies and climate modeling are focusing increasingly on subgrid scale processes as a way to improve model performance (Klink, 1995;Lynch et al, 1995;Ghan et al, 1997) as great variation can occur within an area of 2° of latitude by 2° of longitude (Klink, 1995). Methods that can capture the general physical characteristics in an area while still reflecting the degree of subgrid cell variability are needed in modeling.…”
