Advancing the State of the Science in Regional Photochemical Modeling and Its Applications

Although the focus in the 1970s was primarily on urban air pollution models, it is well known that pollution problems such as acid rain, ozone, and fine particulate matter are regional in scope, requiring regional-scale multipollutant models. In North America and Europe, several models have been developed by different research groups. These models have undergone extensive development during the last three decades worldwide because of the increased concern regarding the impacts of atmospheric pollution on human health and sensitive ecosystems. For example, during the 1980s, regional-scale …
