SmogRank / World / Germany / Lower Saxony / 2024

Most polluted cities in Lower Saxony, Germany, 2024

14 cities in Lower Saxony, Germany ranked by their average PM2.5 over the 366 days; 14 above the WHO annual guideline (5.0 µg/m³). Worst: Oldenburg at 9.3 µg/m³, #673 of 2,052 cities in the world. Cleanest: Goslar at 6.2. 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.
