RSQAQ - Hourly Air Quality Index Data

This dataset contains the validated hourly results of the [Air Quality Index (AQI)] (https://www.iqa.environnement.gouv.qc.ca/contenu/index.asp) and its sub-indices for each station in the [Quebec Air Quality Monitoring Network (RSQAQ)] (https://www.environnement.gouv.qc.ca/air/reseau-surveillance/Carte.asp).

The results of the stations in the city of Montreal are not included. To obtain them, consult the dataset [RSQA - air quality index (historical)] ([measured on the island of Montreal] (https://www.donneesquebec.ca/recherche/dataset/vmtl-rsqa-polluants-gazeux)).

The IQA is an information and awareness tool designed to inform the population about the quality of ambient air in Quebec.
