About air quality in Beijing

This page tracks the Beijing Air Quality Index using measurements from public monitoring stations aggregated by OpenAQ, reported on the US EPA AQI scale — the international standard used by most worldwide air-quality services. The index runs from 0 to 500; the higher the number, the more polluted the air and the greater the health concern. It is calculated here from fine particulate matter (PM2.5) and coarse particulate matter (PM10), the pollutants that most often drive urban air quality.

Air quality in Beijing varies through the day and across seasons with traffic, industry, weather and — in many regions — seasonal biomass or crop burning. Checking the live reading before outdoor exercise or a commute helps you decide whether to adjust timing, wear a mask, or keep windows closed. We only display a number when a recent station reading exists; if you see "data updating", we are waiting on fresh data rather than showing an estimate.
