The simulation of surface heat fluxes in a land surface-atmosphere model

Abstract

A modified soil-canopy-boundary layer model based on Ek and Mahrt is presented to simulate surface heat fluxes on a daily basis. The model is validated against independent published bare soil data from Agassiz, Canada, and observations taken over sparse and dense vegetation as part of the HAPEX-MOBILHY (Hydrological Atmospheric Pilot Experiment-Modelisation du Bilan Hydrique) experiment. Simulated surface energy components are shown to be in close agreement with the observations, and the sensitivity of the parameterization is evaluated. -Authors
