Lucerne's air quality faces Switzerland's most distinctive lake basin challenge, with the city's position in the enclosed Reuss valley at the foot of Mount Pilatus creating topographic concentration of vehicle emissions from the N2 motorway and tourism traffic under frequent winter inversions. The Lake Lucerne breeze provides distinctive seasonal ventilation, while the surrounding Bernese and Lucerne Alps deliver clean Föhn air periodically from the south throughout the year.

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.
