Description:
Because verifiable numerical models that incorporate all processes determining the dispersion, transformations, and deposition of emitted pollutants associated with acidic deposition from the atmosphere are only now under development, it was deemed worthwhile to determine whether other methods might be available to empirically relate acidic deposition to precursor emissions. An indirect experimental plan, named the combined experimental approach, was developed. The approach consists of three major components: long-range tracer experiments; short-range experiments, including reactive tracers, local deposition experiments, and local source modulation; and routine monitoring of aerometric parameters. Analyses of data would provide estimates of source contributions to deposition at receptor sites. The collected data would also be used for developing and testing upgraded regional models and model components. The report describes the workshop used to develop the general experimental design and the follow-up analyses of the various components. Some of the design sections describe experiments that will yield data for evaluation of acid deposition models. Finally, the costs of the various experimental efforts are described.
