In Châteauroux, agricultural traffic and river-valley industry is the primary local source affecting air quality, near the Indre, though the wide Loire valley allows steady airflow, limiting how much pollution can build up locally. Cold, still winter spells are the main risk for particulate build-up, while summer usually sees cleaner air except during occasional heatwave-driven ozone episodes.

When is air pollution at its worst in Châteauroux?
In Châteauroux, 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. The presence of Loire valley cereal farmland and vineyards in the area adds another layer to the local pattern.
Are air quality levels in Châteauroux 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.
