Nitrogen Dioxide Over the United States, 2005-2021

There is a newer version of this story located here:
Nitrogen dioxide can impact the respiratory system, and it also contributes to the formation of other pollutants including ground-level ozone and particulates. The gas is produced primarily during the combustion of gasoline in vehicle engines and coal in power plants. Air pollution has decreased even though population and the number of cars on the roads have increased. The shift is the result of regulations, technology improvements and economic changes, scientists say.

This visualization shows tropospheric column concentrations of nitrogen dioxide as detected by the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite, averaged yearly from 2005-2021.
