Les données peuvent être détaillées par polluant, par département et/ou par niveau (1-Information et recommandation, 2-Alerte). Attention, un seul épisode peut concerner plusieurs polluants, il ne faut donc pas les sommer, mais modifier les paramètres de la route /stats selon les besoins. Pour plus d'informations sur les épisodes de pollutions ### Procédures préfectorales (/pref) Recence uniquement les procédures préfectorales activées. Lorsque les critères sont atteints pour un épisode à venir, AtmoSud déclenche par délégation, une procédure préfectorale pour l’information de la population et la mise en œuvre de mesures adaptées en fonction du type d’épisode. Il s’agit de mesures visant à réduire les émissions et relevant des préfectures de département concernées. Ces procédures sont déclenchées le jour ou la veille de l'épisode et se voient attribuer un niveau allant de l'information recommandations à l'alerte niveau 2. ### Episodes observés (/obs) Recence uniquement les épisodes constatés/observés. Les épisodes observés s'appuient sur les mêmes critères statistiques que les épisodes prévus et se basent sur les modélisations, a posteriori, qui incluent les concentrations observées.","free_access_class":"FREE_NO_AUTH","auth_type":"NONE","homepage_url":null,"docs_url":null,"repo_url":"https://www.data.gouv.fr/api/1/datasets/r/37191c49-56dd-4576-a95b-e5781db3c619","status":"ACTIVE","verification_state":"VERIFIED","tags":[],"logo_url":"https://www.google.com/s2/favicons?sz=64&domain=data.gouv.fr","primary_source_url":"https://www.data.gouv.fr/api/1/datasets/r/37191c49-56dd-4576-a95b-e5781db3c619","extraction_confidence":"0.30","created_at":"2026-07-07T11:55:21.114Z","updated_at":"2026-08-22T01:27:19.881Z","last_verified_at":"2026-08-21T17:47:55.428Z","deprecated_at":null,"ranking_score":56,"last_ranked_at":"2026-08-22T01:27:19.881Z","last_seen_at":null,"last_validated_at":null,"last_uptime_at":null,"search_vector":"'/obs':190B,312B,523B,643B
