Foligno's air quality reflects the Topino river valley in the Umbrian plain, with vehicle traffic on the SS75 and surrounding manufacturing and food industry contributing local sources. The surrounding Umbrian Apennines and the Topino-Clitunno river plain create topographic variation, while the valley's partial enclosure can concentrate emissions under calm winter conditions and the Umbrian plain's occasional winter temperature inversions affect the entire Foligno-Spoleto corridor throughout the year.

When is air pollution at its worst in Foligno?
In Foligno, reduced air quality is most noticeable when oak and linden pollen peaks, and on days affected by vehicle traffic on the SS75 and nearby manufacturing and food industry; things typically settle down again once the weather pattern shifts.
Are air quality levels in Foligno 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.
