Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.
