1 city in Maharashtra, India ranked by their average PM2.5 over the 31 days. The only one: Mumbai at 52.2 µg/m³, #9 of 1,965 cities in the world. A city needs measurements on 70% of the days to be ranked.
Maharashtra has 26 cities ranked over the last 30 days, but only 1 here: most of its monitors have no readings for October 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.
