Geneva's air quality is generally good, benefiting from the Lake Geneva corridor and the Jura and Alpine mountain system providing consistent ventilation from the southwest and northeast. Vehicle traffic on the A1 and surrounding cantonal road network and the concentrated international organisation and aviation activity from Geneva Airport contribute the primary local emissions, while wood burning adds seasonal PM2.5 in winter and the Bise northeasterly wind from the Swiss Plateau periodically provides exceptional clean-air episodes.

From spring, conditions steadily pick up around the lake, and summer stays mostly clear aside from a rare ozone spike, with autumn usually just as settled.
Are air quality levels in Geneva 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.
