Sevran's air quality reflects Greater Paris' northeastern inner suburb adjacent to the Roissy Charles de Gaulle Airport approach, with aviation and vehicle emissions generating elevated NOₓ alongside vehicle traffic on the A3 motorway and the surrounding industrial and residential character. The flat Seine plain provides limited dispersal, while the airport approach corridor makes Sevran one of the Paris metropolitan area's more aviation-influenced municipalities alongside the industrial character that maintains elevated readings throughout the year.

When is air pollution at its worst in Sevran?
In Sevran, the combination of agricultural traffic and river-valley industry and heavy oak and plane pollen in spring is what most affects sensitive groups; the wide Loire valley allows steady airflow, so poor conditions rarely last more than a couple of days. Nearby Loire valley cereal farmland and vineyards add a further seasonal factor.
Are air quality levels in Sevran 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.
