Sitting on the Lombard plain near Como, Mariano Comense sees vehicle traffic in the dense Milan metropolitan belt as the dominant local influence on air quality, while the surrounding Lombardia terrain affects how pollutants disperse. Calm, still conditions tend to let levels build here more than in breezier weather, and the local topography around Mariano Comense can trap emissions for longer stretches during stable atmospheric periods.

When is air pollution at its worst in Mariano Comense?
Mariano Comense residents most often flag air quality concerns during olive and oak pollen season and spells of vehicle traffic in the dense Milan metropolitan belt; the remaining months across Lombardia tend to be considerably calmer and clearer.
Are air quality levels in Mariano Comense 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.
