Most polluted cities in Turkey, March 2023
Turkey's government monitoring network publishes no terms that let us reuse its readings, so we leave it out, and most cities in Turkey are missing here, not clean. The cities shown are measured by community low-cost sensors, tagged as such. Why.
No city in Turkey had measurements on 70% of the days, so March 2023 has no board for Turkey.
OpenAQ's archive, where our readings come from, has almost none for 20 of these 31 days. Cities in the United States and Europe have them 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.
