Hourly contaminant concentrations measured continuously by the Quebec Air Quality Monitoring Network (RSQAQ). To consult the descriptive statistics of these data, look for the RSQAQ-Statistics-Descriptive-Data-Continuous-Data data. If you have any questions about this data, contact the Info-Air department:. These data exclude those [measured on Montreal Island] (https://www.donneesquebec.ca/recherche/dataset/vmtl-rsqa-polluants-gazeux). For detailed instructions on how to open and navigate data files to easily find accurate data, see the [RSQAQ: Navigating Air Quality Data] tutorial (https://www.youtube.com/watch?v=3bLBUOmMEFk).
