SmogRank / Rankings

All 2,681 cities by PM2.5, last 24 hours

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

CPCB in India: no readings since 12 Oct (488 monitors). Their cities are missing from this board, not clean.

Hide the 1,152 cities with only 1–2 sensors

These cities have only one or two low-cost sensors, and one cheap unit can read well off, so they take no rank. They sit at their place by value, marked –, and every ranked city keeps its number.

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.
