Hourly ambient fine particulate matter (PM2.5) concentrations in micrograms per cubic metre are recorded at provincial monitoring stations across Nova Scotia. Government of Nova Scotia provides this data up to the end of 2024. Since 2018, the Halifax station is co-located with gas analyzers measuring NOx, NO2, NO, SO2, O3, and CO.
Use Cases
- Analyze hourly PM2.5 pollution trends based on time-series data from Nova Scotia stations.
- Correlate particulate matter levels with co-located gas pollutants based on the description of the Halifax Johnston station.
- Model regional air quality patterns based on data from provincial monitoring stations across Nova Scotia.
- Assess public health exposure to fine particulate matter based on hourly concentration measurements.
Strengths
- Hourly granularity provides high temporal resolution for analysis.
- Data spans from at least 2018 to the end of 2024, offering a multi-year time series.
- Co-location with gas analyzers at the Halifax Johnston station since 2018 suggests potential for multi-pollutant correlation.
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 stations in Nova Scotia.
