This API provides the ATMO air quality index for the Pays de la Loire region in France, covering the period 2017-2020. The index is a daily indicator graded from 1 (very good) to 10 (very bad) that gives a simple, overall characterization of air quality in an urban area. It is composed of four sub-indices, each representing a specific air pollutant. The dataset is published via the Pays de la Loire regional open-data portal and is freely accessible without authentication.L’indice de qualité de l’air est un indicateur journalier gradué de 1 (très bon) à 10 (très mauvais) qui permet de caractériser de manière simple et globale la qualité de l’air d’une agglomération urbaine.
