Most polluted cities in Portugal, February 2024

6 cities in Portugal ranked by their average PM2.5 over the 29 days. Worst: Amora at 11.4 µg/m³, #364 of 2,036 cities in the world. Cleanest: Faro at 3.3. 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.
