Most polluted cities in Nova Scotia, Canada, February 2023

No city in Nova Scotia, Canada had measurements on 70% of the days, so February 2023 has no board for Nova Scotia, Canada.

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.
