Laval's air quality is driven largely by river-port traffic and light industry, close to the Loire, while the Loire estuary and Atlantic winds ventilate the area, which provides a natural check on pollution build-up. Conditions are fairly even across the year, with the calmest late-summer days occasionally allowing modest ozone build-up before Atlantic winds clear it again.

Are air quality levels in Laval 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.
