Nova Scotia Ambient Sulphur Dioxide Hourly Data for Sydney

Hourly ambient sulphur dioxide (SO2) concentration data in parts per billion from provincial air quality monitoring stations across Nova Scotia. The dataset includes data up to the end of 2024, with a documented gap for the Sydney station from October 15, 2024 to January 15, 2025. The data is provided by the Government of Nova Scotia and was last updated on the platform in April 2026.

Use Cases

• Analyze hourly SO2 pollution trends based on the time-series nature of the data
• Model air quality impacts from industrial sources based on station-specific concentration readings
• Validate regulatory compliance and assess emission control effectiveness based on provincial monitoring data
• Identify seasonal or diurnal patterns in SO2 concentrations based on the hourly measurement frequency

Strengths

• Data is explicitly hourly, providing high temporal resolution
• Includes a documented and specific data gap for Sydney station (Oct 15, 2024 to Jan 15, 2025)
• Coverage extends up to the end of 2024
• Published under the OGL-CA-2.0 open license

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to provincial monitoring station locations
