SmogRank / World / Chile / February 2024

Most polluted cities in Chile, February 2024

42 cities in Chile ranked by their average PM2.5 over the 29 days. Worst: Puerto Montt at 28.6 µg/m³, #109 of 2,139 cities in the world. Cleanest: Puerto Aysén at 14.0. A city needs measurements on 70% of the days to be ranked.

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.
