SmogRank / World / Ireland / March 2023
Most polluted cities in Ireland, March 2023
No city in Ireland had measurements on 70% of the days, so March 2023 has no board for Ireland.
OpenAQ's archive, where our readings come from, has almost none for 20 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; many cities elsewhere are missing from this board, not clean. Why.
