Canada's AQHI+ for PM2.5 (1 point per 10 µg/m³), which is defined on hourly values. Show values as: µg/m³ · US AQI · India AQI · China AQI · European AQI · UK DAQI · Canada AQHI+. About the scales

Updated 2026-10-02 05:07 UTC. Values are PM2.5 (fine particles), the median of each city's monitors, as the Canada AQHI+ PM2.5 sub-index.
