Global Sources of Local Pollution: An Assessment of Long-Range Transport of Key Air Pollutants to and from the United States (2009)

Recent advances in atmospheric monitoring and modeling have helped confirm that air pollution can be transported aloft across oceans and continents, affecting air quality and ecosystems far from the original pollution sources. It is currently quite difficult to quantify this transport or its impacts, but there is evidence that in some cases, the influence of long-range pollution transport can be
