The AQI tracks ozone (smog) and particle pollution (tiny particles from ash, power plants and factories, vehicle exhaust, soil dust, pollen, and other pollution), as well as four other widespread air pollutants.
Our Air Quality Index is calculated based on averages of all pollutant concentrations measured in a full hour, a full 8 hours, or a full day.
