March kicks off 2024 ozone season

March kicks off 2024 ozone season

March 1 marked the beginning of the 2024 ozone season as state and local environmental agencies renew their daily air quality forecasts for ozone across North Carolina. 

Ground-level ozone forms in the air when nitrogen oxides react with hydrocarbons in the presence of heat and sunlight. High levels of ozone have been linked to heart and lung conditions, including asthma, particularly in young children, older adults and other sensitive groups. 

Ozone levels on North Carolina’s highest ozone days continue to decline due to steady reductions in emissions from its primary air pollution sources: power plants, industry and motor vehicles.

The air quality forecasts for all of North Carolina are available through the Air Quality Portal, a mobile-friendly website launched in partnership with the North Carolina State Climate Office. Forecasts are also available through the U.S. Environmental Protection Agency’s AirNow website and app.
