Results from sensitivity studies from two wet deposition models will be presented. One model (the RSM) has been designed for inclusion in the Regional Acid Deposition Model (RADM). The RSM can easily simulate a variety of meteorological and initial chemical conditions, and is therefore suited for a number of sensitivity studies. It has this flexibility as a result of the steady-state assumptions associated with its meteorology. The other model makes use of processor simulations defining detailed, time-dependent cloud simulations, which are then used to drive a version of the PLUVIUS series reactive scavenging model, which incorporates wet removal and aqueous chemistry. The latter approach is less suitable for meteorological sensitivity studies, because of the need to reinitialize the preprocessor simulations. Both models are designed to stimulate aerosol and gas scavenging processes and aqueous chemical reactions within individual storm systems. These models operate on horizontal scales of about 100 /times/ 100 km, rather than the 1000-km scales associated with long-range transport or regional-scale air chemistry models. 9 refs., 16 figs.
