SmogRank / World / Luxembourg / February 2023

Most polluted cities in Luxembourg, February 2023

1 city in Luxembourg ranked by their average PM2.5 over the 28 days. Worst: Luxembourg at 13.9 µg/m³, #436 of 1,166 cities in the world. 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.
