The UK's Daily Air Quality Index (1 to 10), PM2.5 bands. Show values as: µg/m³ · US AQI · India AQI · China AQI · European AQI · UK DAQI · Canada AQHI+. About the scales

Updated 2026-10-02 04:07 UTC. Values are PM2.5 (fine particles), the median of each city's monitors, as the UK DAQI PM2.5 sub-index.
