Val di Fiemme's air quality benefits from its exceptional Trentino-Alto Adige Dolomites alpine valley position at approximately 1,000 metres on the Avisio River, with consistent alpine valley breezes providing clean natural ventilation through this famous Nordic skiing and Marcialonga cross-country ski marathon corridor. Very modest vehicle traffic and the tourism and agricultural corridor contribute minimal local sources, while the extraordinary Dolomites UNESCO alpine setting and the clean mountain climate generally maintain excellent to good conditions throughout most of the year.

When is air pollution at its worst in Val di Fiemme?
Air quality dips in Val di Fiemme mostly track mountain pine spruce and larch pollen peaks and periods of very modest vehicle traffic and the tourism and agricultural corridor contribute minimal local sources; otherwise, the area's setting generally supports clear, well-ventilated conditions.
Are air quality levels in Val di Fiemme 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.
