What is AQI?

The Air Quality Index (AQI) is used for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you.

Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health. Source for further information:
