16 cities in Canary Islands, Spain ranked by their average PM2.5 over the 31 days. Worst: Las Palmas de Gran Canaria at 10.7 µg/m³, #546 of 1,375 cities in the world. Cleanest: Telde at 4.0. A city needs measurements on 70% of the days to be ranked.

Ranked by unhealthy days: the share of each city's measured days with a daily mean over 35.4 µg/m³ (US AQI 101+), Unhealthy for Sensitive Groups or worse on the US EPA's scale. Ties go to the higher average.
