Besso's air quality reflects its dense central Lugano position, with vehicle traffic on surrounding streets contributing local sources within the enclosed Ceresio lake basin's inversion-prone topography.

When is air pollution at its worst in Besso?
Besso sees its worst air quality on windless winter mornings, when vehicle traffic and tourism pool in this mild southern basin under a shallow layer of still air. Warmer months bring noticeably better airflow through this mild valley, with only the occasional summer ozone spike breaking an otherwise clean pattern through spring and autumn.
Are air quality levels in Besso 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.
