SmogRank / World / Switzerland / February 2024

Most polluted cities in Switzerland, February 2024

5 cities in Switzerland ranked by their average PM2.5 over the 29 days. Worst: Lugano at 11.9 µg/m³, #330 of 2,036 cities in the world. Cleanest: Basel at 7.4. 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.
