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 data is provided by the Government of Nova Scotia and was last updated on April 17, 2026. The Halifax Johnston station replaced the nearby Halifax Vogue station, which ceased monitoring at the end of 2017.
Use Cases
- Modeling hourly NOx pollution trends based on the hourly time-series data
- Analyzing seasonal or diurnal patterns of NO2 concentrations based on the long-term hourly record
- Comparing air quality between monitoring station locations based on the provincial station network
- Assessing the impact of station relocation based on the replacement of the Halifax Vogue station
Strengths
- Hourly temporal resolution provides detailed time-series data
- Data spans multiple years up to the end of 2024
- Station replacement history is documented, providing context for continuity
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
