Colombes' air quality reflects Greater Paris' northwestern inner suburb, with the A15 motorway and surrounding industrial and residential corridor generating elevated NOₓ alongside the dense urban character. The Seine river provides limited ventilation, while prevailing westerlies carry Atlantic air through the Paris basin and the industrial and logistics character keeps readings among the higher values in the greater Paris northwestern metropolitan area.

When is air pollution at its worst in Colombes?
In Colombes, the worst combined pollen and air quality days tend to come when agricultural traffic and river-valley industry coincide with the peak oak and plane pollen season in spring; the wide Loire valley allows steady airflow, so conditions usually improve within a day or two. Nearby Loire valley cereal farmland and vineyards add a further seasonal factor.
Are air quality levels in Colombes 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.
