The US EPA's Air Quality Index for PM2.5 (2024 breakpoints). Show values as: µg/m³ · US AQI · India AQI · China AQI · European AQI · UK DAQI · Canada AQHI+. About the scales

Not covered: the government monitoring networks of China, Turkey and Iran, which publish only on their own websites. We are building the reader for China's network. The networks of Turkey and Iran don't answer requests from outside their countries, so we can't read them. Most cities there are missing from this board, not clean. Why.

SmogRank, all cities ranked by mean PM2.5 (µg/m³), last 7 days to 14 Oct 2026, 07:00 UTC: each city's mean of its daily means, cities measured on 5 or more of the 7 days. Monitor data from national networks via OpenAQ and the publishers listed at smogrank.com/sources. smogrank.com/rankings?w=7d. Ranked on low-cost sensors, with no reference monitor in the city: #1 Kuala Lumpur, #3 Dhaka, #4 Faisalabad, #5 Kasur, #6 Gujranwala, #7 Lahore, #8 Peshawar, #9 Multan and #10 Jakarta.
