RSQA - real-time air quality index (daily)

RSQA - real-time air quality index (daily) The City of Montreal measures air quality in the form of a numerical value called the “Air Quality Index (AQI).” This data set provides access to daily AQI values, updated every hour, approximately 50 minutes after the hour. For example, the 13:00 data is available around 13:50, for all three resources. ***Note: ** the AQI systems do not change the time: they always use Eastern Standard Time (EST) and not Eastern Daylight Time (EDT). Thus, in the example above, around 13:50 EDT, the most recent data available will be from 12:00 EDT.* Historical values, updated daily, are available [here] (rsqa-iqa-historical). The [list of stations] (rsqa-liste-des-stations) and [sectors] (rsqa-geographic-sectors) linked to RSQA data is also available. 2025-03-05 Government and Municipalities of Québec donneesouvertes@montreal.ca Nature and Environment Data visualizationHTML https://carte-qualite-air.montreal.ca/ Detailed AQI per station in real time (Daily)CSV https://donnees.montreal.ca/dataset/3e9f7b96-3f25-4404-a5ad-22d9a31060e6/resource/a25fdea2-7e86-42ac-8301-ca77db3ff17e/download/rsqa-indice-qualite-air.csv AQI per station in real time (Daily)CSV https://donnees.montreal.ca/dataset/3e9f7b96-3f25-4404-a5ad-22d9a31060e6/resource/ccd5a4b7-cbca-4f5f-a746-ad8c576af374/download/rsqa-indice-qualite-air-station.csv Real-time sector AQI (Daily)CSV https://donnees.montreal.ca/dataset/3e9f7b96-3f25-4404-a5ad-22d9a31060e6/resource/9c7434e9-f5af-4154-991c-293fbd5cb626/download/rsqa-indice-qualite-air-secteur.csv Original metadata (https://www.donneesquebec.ca)HTML https://www.donneesquebec.ca/recherche/fr/dataset/3e9f7b96-3f25-4404-a5ad-22d9a31060e6
