Daily average concentrations of the main regulated ambient air pollutants, measured by the permanent European monitoring network across the Sud region of France. Data come from automatic field measurement stations, with average concentrations calculated according to the methodological guide for such calculations. The dataset is published by Métropole Aix-Marseille-Provence and provides a local, ongoing record of air quality useful for monitoring pollution levels and trends within the metropolitan area.Concentrations moyennes journalière 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...
