Most polluted cities in Trentino-Alto Adige, Italy

4 measured cities, last 30 days; 0 above the WHO 24-hour guideline. The most unhealthy days: Trento, Italy, 0 of 28 measured days.

25 monitors in Italy haven't reported for more than two days. 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.

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.

Estimated: cities without a monitor

Trentino-Alto Adige 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.
