Air quality in Aci Catena, estimated
Sicily, Italy. No ground monitor we can use is in this city, so these numbers are model estimates, not measurements.
Likely between 5 and 21 µg/m³ (28–73 US AQI): the model's 7-day average to 7 Oct 2026, about 0.7× the WHO 24-hour guideline.
30-day average, estimated: ≈ 10 µg/m³
Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS). Only 2 measured cities are within 300 km, too few to adjust it, so this is the raw model value, which can be off by half or double. Not ranked on SmogRank's boards.
