Atmospheric Modeling

Abstract

Although air quality models have been applied historically to address issues specific to ambient air quality standards (i.e., one criteria pollutant at a time) or welfare (e.g.. acid deposition or visibility impairment). they are inherently multipollutant based. Therefore. in principle air quality models can be applied in the context of integrated emissions control programs that are designed to optimally address all of the above air quality issues simultaneously. Limitations arise. however. as additional chemical species of concern are identified that are not currently treated in air quality models. Such cases require the compilation of emission inventories and boundary conditions for these new chemical species and the addition of chemical and physical mechanisms in the model to treat their transformation and deposition.
