Impact of climate change alone and in combination with currently planned emission control strategies are investigated to quantify effectiveness in decreasing regional ozone and PM(2.5) over the continental U.S. using MM5, SMOKE, and CMAQ with DDM-3D. Sensitivities of ozone and PM(2.5) formation to precursor emissions are found to change only slightly in response to climate change. In many cases, mass per ton sensitivities to NO, and SO(2) controls are predicted to be greater in the future due to both the lower emissions as well as climate, suggesting that current control strategies based on reducing such emissions will continue to be effective in decreasing ground-level ozone and PM(2.5) concentrations. SO(2) emission controls are predicted to be most beneficial for decreasing summertime PM(2.5) levels, whereas controls of NO, emissions are effective in winter. Spatial distributions of sensitivities are also found to be only slightly affected assuming no changes in land-use. Contributions of biogenic VOC emissions to PM(2.5) formation are simulated to be more important in the future because of higher temperatures, higher biogenic emissions, and lower anthropogenic NO(x) and SO(2) emissions.
