SmogRank / Rankings

517 cities by checked peak, last 7 days

Every city with enough measurements in this window, worst first.

CPCB in India: no readings since 12 Oct (488 monitors). EEA and Catalonia Medi Ambient I Sostenibilitat in Spain: no readings since 13 Oct (336 monitors). Their cities show older figures or are missing from this board, not clean.

Ranked by checked peak: each city's worst 6 hours in a row, read by at least 2 monitoring places 3 km or more apart (the second-highest place's average over those hours), so one faulty monitor or smoke over one corner of a city can't set it. 517 of these 2,894 cities are ranked: those measured at 2 or more such places on enough of the days.

What stands behind each figure: Checked at 2+ sites One reference monitor Low-cost sensors About these marks

Low-cost sensors: consumer units, counted only in cities with no government-grade monitor; they read close to reference monitors on the whole, but 15 to 25% high in humid air. How we use them.

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 checked peak PM2.5 (µg/m³), last 7 days to 14 Oct 2026, 06:00 UTC: each city's worst 6 hours in a row, read by 2 or more monitoring places 3 km or more apart, cities with a checked peak on 5 or more of the 7 days.
