Most polluted cities in Aichi, Japan, 2023

No city in Aichi, Japan had measurements on 70% of the days, so 2023 has no board for Aichi, Japan.

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.

Aichi has 23 cities ranked over the last 30 days, but none here: most of its monitors have no readings for 2023 in OpenAQ's archive, where ours come from, or too few to rank. Cities missing from this board weren't clean, just not measured.
