SmogRank / World / Sweden / January 2023

Most polluted cities in Sweden, January 2023

6 cities in Sweden ranked by their average PM2.5 over the 31 days. Worst: Visby at 9.1 µg/m³, #426 of 993 cities in the world. Cleanest: Umeå at 3.0. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 7 of these 31 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; elsewhere a city's average is over its other days. Why.
