Abstract
Models predicting deposition rates of chemical species onto the surface of hills by washout and turbulent deposition have been developed. The models include aqueous phase sulphur dioxide chemistry which is allowed to proceed within an evolving dynamical-microphysical framework. Individual droplet chemistry may be examined and allowance made for the finite time required for equilibrium to be achieved between droplets and soluble gases. Comparisons are made with comprehensive field data obtained at the UMIST Great Dun Fell site. Predicted conversion rates for sulphur dioxide to sulphate are found to be in good agreement with field measurements. The concentration of sulphate in collected rainwater is also found to be consistent with that observed.
