Abstract | Wind erosion and dust emission models are essential to estimate the lateral and vertical fluxes of carbon and nutrients between terrestrial and marine ecosystems and reduce uncertainty about dust radiative forcing of climate models. Wind erosion models approximate the turbulent transfer of momentum by surface roughness elements using roughness density (lateral cover or the frontal area index, Lc). Instead of using the aerodynamic roughness length (z0) Raupach et al. (1993) demonstrated using Marshall's (1971) wind tunnel data how the threshold friction velocity ratio Rt could be estimated as Rt(Lc). However, estimation of Lc over large areas (e.g., continents) is difficult and often approximated using classifications of cover (bare surfaces and vegetation type). |
