    Abstract

    When parameterizing turbulent energy fluxes in advanced land surface models, it is common to include four aerodynamic resistances and one surface resistance. We have evaluated the performance of one land surface model by comparing it against observed data collected over 25 months in the Amazon. It was found that the simulated sub-canopy evaporation was excessive, and the omission of vapour pressure deficit (VPD) in calculating the stomatal resistances below the canopy and adding VPD into the calculation of transpiration improved the overall simulation.
