Quimper's air quality benefits from its exceptional Finistère Atlantic peninsula position, with some of Europe's most consistent and powerful Atlantic westerlies providing outstanding natural ventilation across this Breton capital at France's westernmost point. Vehicle traffic on the N165 and surrounding agri-food and services industry contribute local sources, while the remarkable Atlantic exposure and the surrounding Breton countryside generally maintain Quimper among France's cleaner major urban environments throughout most of the year.

Are air quality levels in Quimper 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.
