Most polluted cities in Angola, 2024
No city in Angola had measurements on 70% of the days, so 2024 has no board for Angola.
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.
