Application of Trajectory Model to Regional Characterization

The heightened awareness among scientists in Europe and North America of the opotential dangers to the ecosystem posed by the input of acidic substances to lakes, soil, and vegetation through the atmospheric medium has spurred the development and application of models to describe the long range transport of pollutants. Most long range transport models are intended for use in characterizing regional patterns over long averaging period, thus allowing significant simplifications in the level of detail required for the treatment of transport an dispersion.
