ABSTRACT
Comparisons of air quality policies involve numerous considerations such as cost, health, effects on vegetation and materials, and aesthetics. Such assessments require difficult scientific and value judgments. These difficulties can also characterize comparisons that consider only physical and chemical air quality indices. We compare ambient tropospheric ozone concentrations from a baseline scenario and seven emissions scenarios for a case study. The resulting air qualities are evaluated based upon spatial and temporal distribution of impacts, exceedances of regulatory standards, concentrations weighted by population density, and a variety of averaging ...
