In Bourg-en-Bresse, valley motorway traffic and light industry is the primary local source affecting air quality, near the Allier, though mountain valley winds alternate with calm temperature inversions, which usually keeps pollution from accumulating for long. Winter is typically the worst season, as cold air settles in the valleys and traps traffic and heating emissions for days at a time; summer sees better dispersion but occasional ozone build-up in the lower valleys.

Are air quality levels in Bourg-en-Bresse 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.
