In Val Thorens, valley motorway traffic and light industry is the primary local source affecting air quality, near the Allier, while mountain valley winds alternate with calm temperature inversions, which provides a natural check on pollution build-up. 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.
