My current research is on wind erosion and dust emission and particularly representing these processes in aerosol and atmospheric transport models to improve regional and global carbon (C), dust (D), energy (E) and water (W) cycles and human impact on global climate. Following Raupach & Lu (2004) I try to balance the fidelity of aeolian processes with the parsimony necessary for large scale models. Albedo, its complement shadow and its parameterisation of aerodynamic shelter across scales has risen above the variety of methods and techniques I've tried over the years including 137Cs, geostatistics, soil bi-directional spectral reflectance measurement and modelling using wind tunnel and field experiments.
