Changes in Ozone Chemical Sensitivity in the United States from 2007 to 2016.

ABSTRACT: Anthropogenic nitrogen oxide (NO_x) and volatile organic compound (VOC) emissions in the U.S. have declined substantially over the last decade, altering the NO_x-VOC chemistry and ozone (O₃) production characteristics of many areas. In this work we use multiple air quality analysis tools to assess how these large reductions in NO_x and VOC have affected O₃ production regimes across the U.S. between 2007 and 2016. We first compare observed and modeled evolution of NO_x-limited and NO_x-saturated O₃ formation regimes using a day-of-week (DOW) analysis. This comparison builds confidence in the model's ability to qualitatively capture O₃ changes due to chemistry and meteorology both within years and a
