Paris' air quality is driven by traffic on the Périphérique and surrounding boulevards, with the Seine corridor channelling westerly winds through the urban core. Calm anticyclonic conditions in winter trap particulates and NO₂ across the dense arrondissements, while the open Île-de-France countryside provides cleaner air on windier days.

When is air pollution at its worst in Paris?
In Paris, the combination of traffic and urban heating and heavy birch and plane pollen in spring is what most affects sensitive groups; the Seine corridor channels westerly winds through the city, so poor conditions rarely last more than a couple of days. Nearby Île-de-France farmland add a further seasonal factor.
Are air quality levels in Paris 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.
