Most polluted cities in Asturias, Spain
No city in Asturias, Spain has enough readings to rank so far this year.
26 monitors in Spain stopped reporting on 6 Oct, 05:00 Madrid time. Cities that rely on them are missing from the 24-hour board and may drop from the longer ones; that isn't clean air, and they return when the data does.
A city joins this ranking with enough days of readings so far this year; none here has that right now, so there is nothing to map or chart.

Estimated: cities without a monitor
Asturias cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
| City | 7-day estimate |
|---|---|
| Mieres | ≈ 8 µg/m³ |
| La Felguera | ≈ 8 µg/m³ |
| Natahoyo | ≈ 8 µg/m³ |
| Corvera de Asturias | ≈ 8 µg/m³ |
