This project will investigate the potential impacts of changing land use and land cover on ozone and particulate matter (PM) air quality in the United States. It will develop an integrated modeling system and quantify the contributing effects from anthropogenic land-use change and also changes in land cover driven by climate change. These changes are expected to affect air quality through various aspects including changes in the natural emissions of ozone and PM precursors and changes in the deposition of ozone and PM as well as their precursors. Some preliminary work has shown that these changes could have potentially large impacts on atmospheric chemistry and air quality.
