RSQAQ: Hourly Air Contaminant Concentrations in Quebec

Hourly contaminant concentrations measured continuously by the Quebec Air Quality Monitoring Network (RSQAQ). The data excludes measurements taken on Montreal Island, which are available in a separate dataset. The dataset is provided by the Government and Municipalities of Québec and was last updated on April 17, 2026.

Use Cases

• Analyze hourly pollution trends based on continuous contaminant concentration measurements
• Model air quality exposure for public health studies based on continuous monitoring data
• Validate and calibrate regional air quality models based on ground-level contaminant data
• Assess compliance with environmental regulations based on continuous contaminant levels

Strengths

• Data is measured continuously, likely providing high temporal resolution
• Linked to a descriptive statistics dataset for summary analysis
• Provided by an official government monitoring network

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data excludes Montreal Island, limiting geographic completeness for Quebec
