Vigevano's air quality faces the Po Valley's enclosed flat basin in the Lomellina agricultural plain, with vehicle traffic on the SS494 and surrounding food manufacturing and textile legacy industry contributing local sources. The flat Po plain's persistent winter anticyclones trap emissions under extended inversion periods, while the Ticino river corridor provides limited ventilation and summer Po Valley ozone from agricultural and vehicle sources adds a significant warm-season dimension throughout the year.

When is air pollution at its worst in Vigevano?
You're quickest to notice worse air in Vigevano when local tree and grass allergens peaks, or due to vehicle traffic on the SS494 and surrounding food manufacturing and textile legacy industry; background levels usually settle back down once the season changes.
Are air quality levels in Vigevano 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.
