Short summary
Ozone (O3) formation in the southeastern US was studied in relation to nitrogen oxide (NOx) emissions using long-term (1990s–2015) measurements of the SEARCH network and U.S. EPA data. NOx emissions decreased by ~ 60 %. Annual fourth-highest daily peak 8 h O3 mixing ratios declined toward ~ 45–50 ppbv at ~1 ppbv yr−1 and O3 exhibited increasing sensitivity to NOx. This study illustrates the value of consistent, long-term measurements of O3 and reactive nitrogen made at both urban and rural sites.
