Canadian Peak Ozone Concentrations at Monitoring Stations

The Canadian Environmental Sustainability Indicators program provides data on ambient concentrations of air pollutants, including ground-level ozone. Information is provided in formats including CSV, HTML, and interactive maps. The dataset is maintained by Environment and Climate Change Canada and was last updated on 2026-04-28.

Use Cases

• Analyze spatial patterns of peak ozone concentrations based on data from local monitoring stations.
• Track national and regional air quality trends against Canadian Ambient Air Quality Standards.
• Model population exposure to ground-level ozone for health impact studies.
• Validate air quality models using observed pollutant concentration data.

Strengths

• Data is provided by the authoritative national environmental agency, Environment and Climate Change Canada.
• Multiple access formats are available, including CSV for analysis and interactive maps for visualization.
• The dataset tracks multiple pollutants, including fine particulate matter, sulphur dioxide, nitrogen dioxide, and volatile organic compounds.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite the last update date of 2026-04-28.
