Global Change and Air Quality
Through the EPA STAR Global Change and Air Quality project, we have developed a modeling program to assess global change impact on U.S. air quality by addressing the following questions: 1) How does global warming affect air quality on regional and urban scales? Directly through warmer temperatures? Indirectly through changes in circulation patterns and changes in land cover? 2) How does land use change due to increased urbanization, global warming, or intentional management (economic forces) affect air quality? 3) How do fire and fire management affect regional air quality and regional haze in the future? 4) What is the role of Asian emissions on US air quality and how does global change influence the impact of Asian emissions? 5) How sensitive is predicted air quality to globally forced boundary conditions (meteorological and chemical)? 6) How sensitive are air quality simulations to changes in emission scenarios, both biogenic and anthropogenic? 7) How sensitive are air quality simulations to uncertainties associated with wildfire projections and with land management scenarios?
