What is the Annual Air Quality Index?

To communicate the health risks caused by long-term exposure to air pollutants, we also report the Annual Air Quality Index(AQI) for those air pollutants with annual World Health Organization (WHO) Air Quality Guidelines (AQG), i.e., NO2 and PM10 or PM2.5. The annual AQI is updated monthly.
