WebOct 13, 2016 · Changing the soil hydraulics from Clapp and Hornberger to van Genuchten explains the majority of the remaining differences in evaporation. However, if the change to the van Genuchten scheme is made whilst the sub-grid scale scheme is switched on, then in general the evaporation declines more rapidly than the original default JULES simulation ... WebGenuchten/Rawls–Brakensiek model performs better than the Campbell/Clapp–Hornberger model. 1. Introduction Soil and vegetation play a key role in atmospheric modeling by partitioning the fluxes and determining temperature and moisture at the interface between soil/ vegetation and the atmosphere. This has led to the in-

In this study, we match CLM0 soil textures, land sur-face classification, and leaf area index (LAI) values to the BATS categories to provide the same model input for the two schemes. 2. Albedos: CLM0 and BATS use the same albedo parameterization for snow and soil, but different approaches for vegetation albedos.
