The State-of-Science/Technology report describes the scientific community's current knowledge regarding the evaluation of regional acidic deposition models. The report summarizes this knowledge by describing the process, as well as the history, of evaluating acidic deposition models and by providing the results obtained from the recent evaluations of such models. The concepts of model evaluation, in general, are discussed in early sections of the report, but particular emphasis is placed on Eulerian-style evaluations. The two Eulerian models covered are the Regional Acid Deposition Model (RADM), which was developed for the United States, and the Acid Deposition and Oxidant Model (ADOM), developed for Canada. The results of evaluating several versions of RADM and ADOM have provided model evaluators with the most current assessment of how reliably these models can address several key issues posed by the National Acid Precipitation Assessment Program (NAPAP). That is, how well can the models predict the change in regional acidic deposition that would result from changes in precursor emissions; the influence of sources in one region on acidic deposition in other sensitive receptor regions; the levels of acidic deposition at certain sensitive receptor regions; and the acidic deposition due to emissions transported across geographical/political boundaries, including the United States-Canadian border.
