Air Quality Index (AQI) is a standardized indicator used to communicate how polluted the air currently is or how polluted it is forecast to become. It aggregates multiple pollutants such as PM2.5, PM10, NO2, and SO2 into a single value to represent overall air quality. Monitoring AQI is crucial for public health as poor air quality can lead to respiratory and cardiovascular diseases.
