pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. Ozone is the main ingredient in smog and has been studied since it began choking cities in the US in the early 1950s. Ozone is formed through a series of chemical reactions, starting with the oxidation of volatile organic compounds (VOCs). Both NO x and VOCs are emitted from fossil fuel combustion, and VOCs can also be emitted from industrial sources.

It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. New NASA-funded research has devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to differentiate among three different sets of conditions that lead to its production.
