Une page sur le site d'AtmoSud vous donnera de nombreuses informations sur le nouvel indice de la qualité de l'air. Un sous-indice et un indice sont composés de quatres valeurs : un qualificatif, un code couleur, une image et une valeur numérique. Bulletin Un bulletin de qualité de l'air regroupe les indices diffusés (calculés) à une même date. Chaque jour AtmoSud diffuse un bulletin des indices calculés pour quatre échéances : de la veille (J-1) au sur-lendemain (J+2). Dates * date_diffusion : date de publication d'un bulletin * date_echeance : date de validité de l'indice Echéances Les indices en J-1 sont consolidés à partir des observations effectués la veille. Les indices J-0, J+1 et J+2 sont des prévisions pour le jour même, le lendemain et le sur-lendemain. Exemples Je souhaite récupérer quotidiennement l'indice de la prévision du jour et du sur-lendemain pour ma commune.
