SmogRank / History / February 1, 2024

Most polluted cities on February 1, 2024

1,315 cities ranked by their average PM2.5 over the day; the worst was Novi Pazar, Serbia, at 116.1 µg/m³. Each city's own local calendar day.

OpenAQ's archive, where our readings come from, has almost none for this day. 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; many cities elsewhere are missing from this board, not clean. Why.
