SmogRank / World / North Macedonia / April 2023
Most polluted cities in North Macedonia, April 2023
No city in North Macedonia had measurements on 70% of the days, so April 2023 has no board for North Macedonia.
OpenAQ's archive, where our readings come from, has almost none for 3 of these 30 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.
