RSQAQ: 4-Minute Air Quality Measurements for Quebec

RSQAQ provides 4-minute concentrations of hydrogen sulfide (H2S) and sulfur dioxide (SO2) measured continuously by the Quebec Air Quality Monitoring Network. The data excludes measurements taken on the island of Montreal and is provided by the Government and Municipalities of Québec. The dataset was last updated on 2026-04-17.

Use Cases

• Monitor short-term fluctuations in pollutant concentrations based on 4-minute measurement intervals
• Analyze patterns of H2S and SO2 emissions based on continuous monitoring data
• Compare air quality data across Quebec regions based on the exclusion of Montreal island data

Strengths

• Data is measured continuously at a high temporal resolution of 4-minute intervals
• Data is provided by an official government monitoring network, the RSQAQ
• Dataset is licensed under CC-BY-4.0, allowing for open reuse

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data excludes measurements from the island of Montreal, limiting geographic completeness
