The eect of increasing fossil fuel combustion in eastern Asia on surface O3 air pollution in the United States is examined with a global three-dimensional tropo- spheric chemistry model. Tripling of Asian anthropogenic emissions from 1985 to 2010 is expected to increase monthly mean O3 concentrations by 2{6 ppbv in the western United States and by 1{3 ppbv in the eastern United States, the maximum eect being in April-June. This increase would more than oset the benets of 25% domestic reductions in anthropogenic emissions of NOx and hydrocarbons in the western United States. Asian influence may be less under the stagnant conditions leading to violations of the U.S. air quality standard. Nevertheless, our results suggest that a global perspective is necessary when designing a strategy to meet regional O3 air quality objectives.

    • ...A number of model studies have examined the effects on US ozone air quality of emissions in Asia (Jacob et al., 1999; Hudman et al., 2004), Europe (Li et al., 2002), and global methane (Fiore et al., 2002b), but there has been little investigation of the nearer-scale international influences from Canada and Mexico...

    • ...There is mounting evidence that the background concentrations of major pollutants (e.g., ozone (O3) and particulate matter (PM)) in North America can increase to a significant level that could offset the national and local control efforts [Jacob et al., 1999; Fiore et al., 2003]...
    • ...For instance, Jacob et al. [1999] indicated that the long-range transport of Asian pollutants could increase the background surface O3 concentrations by 2–6 ppb in the western United States, which will offset up to 25% of O3 control efforts in this region...
