STAR 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:

  • 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?
  • How does land use change due to increased urbanization, global warming, or intentional management (economic forces) affect air quality?
  • How do fire and fire management affect regional air quality and regional haze in the future?
  • What is the role of Asian emissions on US air quality and how does global change influence the impact of Asian emissions?
  • How sensitive is predicted air quality to globally forced boundary conditions (meteorological and chemical)?
  • How sensitive are air quality simulations to changes in emission scenarios, both biogenic and anthropogenic?
  • How sensitive are air quality simulations to uncertainties associated with wildfire projections and with land management scenarios?
