NASA Images Highlight U.S. Air Quality Improvement - Release Materials

Anyone living in the U.S. for the past decade may have noticed a change in the air. The change is apparent in NASA satellite images that demonstrate the country's reduction of air pollution, or more specifically, nitrogen dioxide.

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 following visualizations show tropospheric column concentrations of nitrogen dioxide as detected by the Ozone Monitoring Instrument on NASA's Aura satellite. Blue and green denote lower concentrations and orange and red areas denote higher concentrations, ranging from 1x1015 to 5x1015 molecules per square centimeter, respectively.
