Abstract: [1] A method for incorporating surface heterogeneity into models of wind erosion and dust emission is presented. Parameters that control threshold shear velocity (bare-soil threshold shear velocity, vegetation cover, and vegetation shape) are parameterized as modified-normal distributions with defined means and coefficients of variation. A parameterized bootstrap (Monte Carlo) approach is used to estimate histograms of threshold shear velocities for vegetated surfaces using the model of Raupach et al. (1993).…
