Most polluted cities in Delhi, India, July 2023
1 city in Delhi, India ranked by their average PM2.5 over the 31 days. The only one: Delhi at 27.4 µg/m³, #47 of 1,375 cities in the world. A city needs measurements on 70% of the days to be ranked.
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.
