Arezzo's air quality reflects the Arno valley's topographic enclosure in Tuscany, with vehicle traffic on the A1 motorway and surrounding gold jewellery, fashion, and manufacturing industry contributing local sources. The Apennine ridgelines create topographic enclosure that concentrates emissions under calm winter conditions, while the Arno valley provides the primary ventilation corridor and summer Etesian winds provide periodic relief.

When is air pollution at its worst in Arezzo?
People in Arezzo tend to notice reduced air quality when headwaters corridor olive and linden pollen peaks, or because of vehicle traffic on the A1 motorway and nearby gold jewellery, fashion, and manufacturing industry; the picture usually improves again once the season turns.
Are air quality levels in Arezzo based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
