Monthly average concentrations of the main regulated ambient air pollutants, measured through the permanent European air-quality monitoring network covering the Sud region of France. Data come from automatic field measurement stations, with average concentrations calculated according to a methodological guide for computing such statistics. The dataset is published by Métropole Aix-Marseille-Provence and provides a basis for tracking air pollution trends and regulatory compliance at local and regional level.Concentrations moyennes mensuelles issues du réseau permanent des mesures européennes des principaux polluants réglementés dans l'air ambiant sur la région Sud. Mesures de terrain automatiques. Les concentrations moyennes ont été calculées conformément au guide méthodologique pour le calcul des s...
