Bergamo's air quality faces the Po Valley's most severe topographic challenge, with the Bergamo prealps creating a dramatic northern wall that traps vehicle and industrial emissions under winter anticyclones in one of northern Italy's most densely industrialised corridors. The city consistently records EU exceedances for both PM2.5 and NO₂ throughout the year.

When is air pollution at its worst in Bergamo?
Bergamo residents notice reduced air quality mainly when oak and chestnut pollen peaks, and during spells of the Bergamo prealps; the picture usually improves again once the season turns.
Are air quality levels in Bergamo 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.
