Abstract

A parameterization for the dry deposition of SO2 is evaluated by means of four statistical sensitivity studies using a sampling-based approach to sensitivity analysis. Measurements over a heathland, grassland and coniferous forest are used to identify those meteorological and vegetation-specific factors which drive the deposition component of the model (model-based studies) and which are most important in the determination of model-measurement discrepancies. Sensitivity indices and scatter plots for monthly average fluxes indicate that the dominant factors are for most months related to non-stomatal components of the deposition flux.
