Annual Ozone Air Quality

Measurement Period: 2020-2022

Filter: none (all Counties)

This indicator gives a grade to each county in the U.S. based on the annual number of high ozone days.

Why is this important?

While ozone is an important shield against ultraviolet rays in the Earth's upper atmosphere, it is a pollutant that can cause health problems at ground level. Ground-level ozone is formed when volatile organic compounds (VOCs) and nitrogen oxides (NOx) react in sunlight; both of these pollutants are found in emissions from vehicles, motorized equipment, factories, and some consumer products. Ozone primarily affects the respiratory tract, causing breathing difficulties, aggravating existing lung diseases, and inflaming lung tissue. Although everyone is susceptible to ozone's effects, children, people with lung disease, and older adults tend to be more sensitive to ozone.

Technical note: The American Lung Association (ALA) assigns grades A-F to counties (A=1; B=2; C=3; D=4; F=5), based on average annual number of days that ozone levels exceeded U.S. standards during the three year measurement period. The air quality data is collected by the EPA and summarized by the ALA.
