AirNow is your one-stop source for air quality data. Our recently redesigned site highlights air quality in your local area first, while still providing air quality information at state, national, and world views. A new interactive map even lets you zoom out to get the big picture or drill down to see data for a single air quality monitor.

AirNow reports air quality using the official U.S. Air Quality Index (AQI), a color-coded index designed to communicate whether air quality is healthy or unhealthy for you. When you know the AQI in your area, you can take steps to protect your health.

AirNow is a partnership of the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration (NOAA), National Park Service, NASA, Centers for Disease Control, and tribal, state, and local air quality agencies. Complete list of AirNow partners. Agencies all over the country send their monitoring data to AirNow for display. The Department of State provides data from U.S. Embassies and Consulates to inform personnel and citizens overseas, and the U.S. Forest Service and NOAA provide fire and smoke data.

AirNow’s centralized data system provides quality control, national reporting consistency, and the ability to distribute data to the public, researchers, businesses, educators, and to other data systems. In AirNow, you’ll find:

Current and forecast air quality maps and data for more than 500 cities across the U.S.
Current and historical data for U.S. Embassies and Consulates around the world
Current fire conditions including fire locations, smoke plumes, and air quality data from permanent and temporary air quality monitors
Air quality data for Canada and Mexico
Enviroflash emails, apps, widgets, and an API
Health and air quality information for
the public
healthcare professionals
teachers and students
weathercasters

The video offers a simple and easy-to-understand overview of climate change. It poses basic questions such as 'What is it?' and 'How will it effect us?' and effectively answers those questions.

The AirNow Fire and Smoke Map provides information that you can use to help protect your health from wildfire smoke. Use this map to see:

Current particle pollution air quality information for your location;
Fire locations and smoke plumes;
Smoke Forecast Outlooks, where available; and,
Recommendations for actions to take to protect yourself from smoke. These recommendations were developed by EPA scientists who are experts in air quality and health.
The Map is a collaborative effort between the U.S. Forest Service (USFS)-led Interagency Wildland Fire Air Quality Response Program and the U.S. Environmental Protection Agency (EPA).
