The N.C. Division of Air Quality and local environmental agencies provide daily air quality forecasts across North Carolina. We use the Air Quality Index (AQI) color code system to quickly relay air quality information in each of the state's 100 counties.
From March 1 through Oct. 31, the daily air quality forecasts include ozone. The forecasts for fine particle matter (PM2.5) pollution are offered year-round.
Air Quality Portal
The Air Quality Portal, launched in March 2022, is the new hub for finding air quality forecasts and related air pollution information. The site is a collaboration between the State Climate Office of North Carolina at NC State University and the North Carolina Division of Air Quality. It features the daily air quality forecasts, our air monitoring tools and information on ozone, particulate matter and other pollutants.

Ambient Information Reporter (AIR)
The North Carolina Department of Environmental Quality’s Division of Air Quality (DAQ) has partnered with the North Carolina State Climate Office to develop a new air quality tool, the Ambient Information Reporter (AIR). The new tool contains statewide weather and air quality observations about past, current, and forecasted air quality events.
The AIR tool was designed by professionals within the meteorological and air quality industries, along with public feedback from targeted groups.
Features of the new tool include both real-time and historical air quality and meteorological observations including satellite-detected fires and smoke, the latest air quality forecast, along with the ability to view graphs and charts of both hourly and daily data trends.
The AIR tool is also available via mobile device for users to access quickly and easily, with the same dataset and functionality as the website version.
Ozone Design Value Predictor Tool
The Division of Air Quality has developed an Ozone Design Value Predictor Tool to track design values at monitors across the state and around the country.
Air Quality Index
The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. Please visit EPA's Air Quality Index to learn more.
