About the Air Quality Index
The Air Quality Index (AQI) converts measured pollutant concentrations — including PM2.5, PM10, ozone (O₃), nitrogen dioxide (NO₂), sulphur dioxide (SO₂), and carbon monoxide (CO) — into a single 0–500 scale. Higher values mean greater health risk. The reading for Delhi reflects a CAMS forecast model and updates throughout the day. Learn what the AQI number means for your body.
