SmogRank / World / Finland / February 2023

Most polluted cities in Finland, February 2023

13 cities in Finland ranked by their average PM2.5 over the 28 days. Worst: Helsinki at 6.4 µg/m³, #1,042 of 1,175 cities in the world. Cleanest: Vaasa at 2.6. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 25 of these 28 days. Cities in the United States and Europe have them from the EPA's and the European Environment Agency's own records of the same monitors; many cities elsewhere are missing from this board, not clean. Why.
