SmogRank / World / Austria / 2023

Most polluted cities in Austria, 2023

16 cities in Austria ranked by their average PM2.5 over the 365 days; 16 above the WHO annual guideline (5.0 µg/m³). Worst: Graz at 14.4 µg/m³, #79 of 1,105 cities in the world. Cleanest: Saalfelden am Steinernen Meer at 6.1. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 56 of these 365 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.
