Air Quality Index (AQI)
The Air Quality Index (AQI) is a measurement system used to communicate the levels of air pollution in a given area to the public. It provides a standardised scale to inform people about the current and forecasted air quality in their area, enabling individuals to take appropriate precautions to protect their health. The AQI considers various air pollutants, such as ozone, carbon monoxide, and nitrogen dioxide, when calculating the overall score.
