Most polluted cities in Liaoning, China, 2024

We don't read China's government monitoring network: it publishes only on its own website, and we are building the reader for it. Most cities in China are missing here, not clean. The cities shown are measured by community low-cost sensors, tagged as such. Why.

No city in Liaoning, China had measurements on 70% of the days, so 2024 has no board for Liaoning, China.

OpenAQ's archive, where our readings come from, has almost none for one of these days. Cities in the United States and Europe have it from the EPA's and the European Environment Agency's own records of the same monitors; elsewhere a city's average is over its other days. Why.

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
