Air pollution can cause serious health problems. Local air quality, like the weather, can change from day to day and can be influenced by local and regional events like wildfires. The U.S. Environmental Protection Agency (EPA) developed the Air Quality Index, or AQI, to make information available about the health effects of the five most common air pollutants.
The AQI is a tool for communicating daily air quality. It uses color-coded categories divided into six categories with each color corresponding to a different level of health concern.
AirNow provides single source reporting using the official U.S. Air Quality Index (AQI). At AirNow you can find air quality data for your state and local area.

AirNow is a partnership of EPA, National Oceanic and Atmospheric Administration (NOAA), National Park Service, NASA, Centers for Disease Control, and tribal, state, and local air quality agencies.
