What Is the Air Quality Index? Ever hear your local weather forecast say that tomorrow will be a "code orange" day for air pollution? That's the Air Quality Index at work. The Air Quality Index, or AQI, is the system used to warn the public when air pollution is dangerous. The AQI tracks ozone (smog) and particle pollution (tiny particles from smoke, power plants and factories, vehicle exhaust ...
The AQI is easy to use. If the AQI predicts a "Code Orange" (unhealthy for sensitive groups) day don't cancel your plans—use the AQI to help you plan a better time or place for them.

The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide.
