SmogRank / World / Pakistan / Punjab / July 2023
Most polluted cities in Punjab, Pakistan, July 2023
1 city in Punjab, Pakistan ranked by their average PM2.5 over the 31 days. The only one: Lahore at 43.2 µg/m³, #25 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.
Punjab has 9 cities ranked over the last 30 days, but only 1 here: most of its monitors have no readings for July 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.

Low-cost sensors: consumer units, counted only in cities with no government-grade monitor; they read close to reference monitors on the whole, but 15 to 25% high in humid air. How we use them.
