Overseas NOx Could Be Boosting Ozone Levels in U.S.

Large amounts of a chemical that boosts ozone production are being transported to North America from across the Pacific Ocean in May, according to a new report by researchers from Georgia Tech. These higher levels of nitrogen oxides (NOx), arriving in late spring, could be contributing to significant increases in ozone levels over North America. The research appeared in volume 33 of the journal Geophysical Research Letters.
