The U.S. Environmental Protection Agency (EPA) is committed to protecting public health by improving air quality and reducing air pollution. This annual report, titled Our Nation's Air, summarizes the nation's air quality status and trends through 2018.
The air quality forecast is a prediction of the day’s overall AQI issued by state and local air quality forecasters. Each dot on this map represents a city or reporting area that issues a forecast. Read more about the air quality forecast. Click on a dot to see forecast info for separate pollutants if available.
This map displays data from reference-grade air quality monitors at U.S. embassies and consulates around the world. Fine particulate matter (PM2.5) data is available for all sites, and ozone data is available for >10 sites.
While some pollutants continue to pose serious air quality problems in areas of the U.S., nationally, criteria air pollutant concentrations have dropped signi˜cantly since 1990 improving quality of life for many Americans. Air quality improves as America grows.
