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.

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

They used satellite-based measurements of urban form and nitrogen dioxideO 2 (n) to explore relationships between urban form and air pollution for a global data set of 1,274 cities. Cities serve as economic and social centers, concentrating people, activities, ideas, and industries. More than half of the world population, 3.9

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Global isoprene emissions from plants are estimated at more than 500 teragrams each year. The latest finding can support the development of better models of global gas-aerosol chemistry.
