The U.S. Environmental Protection Agency (EPA) issues a daily report for pollution levels known as the Air Quality Index (AQI). The AQI provides information on the quality of air in different regions, indicating how polluted the air currently is or how polluted it is forecast to become. It categorizes pollution levels into ranges that correspond to potential health effects for the general public and sensitive groups. This helps individuals make informed decisions about outdoor activities based on air quality.
