Hourly ambient nitrogen oxides (NOx, NO2, NO) data in parts per billion from provincial air quality monitoring stations across Nova Scotia up to the end of 2024. The Sydney station was offline from October 15, 2024 to January 15, 2025 to facilitate moving the station; data is not available for Sydney during that time period. The dataset is provided by the Government of Nova Scotia and was last updated on April 17, 2026.
Use Cases
- Model hourly NOx concentration trends based on time-series data
- Analyze seasonal or diurnal patterns of NO2 pollution based on hourly readings
- Assess the impact of station relocation on data continuity based on the documented outage period
- Compare pollutant levels across Nova Scotia monitoring stations based on provincial coverage
Strengths
- Hourly temporal resolution provides granular data for time-series analysis
- Data spans multiple nitrogen oxide species (NOx, NO2, NO)
- Explicit documentation of a known data gap (Sydney station offline Oct 15, 2024 to Jan 15, 2025)
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 monitoring station placement
