What the naked eye can’t see are the hundreds of chemical reactions taking place to produce that pollution. NASA science can reveal a more complete picture of atmospheric chemistry.

A NASA visualization shows 96 chemical species that help form one common air pollutant — surface ozone. While ozone in the stratosphere is critical to maintaining life on earth, surface ozone is a toxic gas to most plant and animal species. This visualization uses the GEOS Composition Forecasting (GEOS-CF) computer model, which incorporates 240 chemical species and how they interact with each other and the weather through over 700 chemical reactions. All of these chemical reactions directly or indirectly impact the formation of ozone.
