Wiltshire Council's Air Quality Management Areas data identifies locations where UK air quality objectives, specifically the annual mean for nitrogen dioxide (40ug/m3), are not being achieved. The source of the exceedances is road traffic emissions, and an action plan is in place to reduce levels. The dataset is published under the OGL-UK-3.0 license and was last updated on 2026-06-16.
Use Cases
- Map pollution exceedance zones based on the defined Air Quality Management Areas.
- Analyze the relationship between road traffic and nitrogen dioxide levels based on the described emission source.
- Monitor the effectiveness of local air quality action plans based on the described mitigation strategy.
Strengths
- Explicitly defines the pollutant of concern as nitrogen dioxide with a specific objective threshold of 40ug/m3.
- Identifies the primary source of pollution as road traffic emissions.
- Links to an external monitoring resource (airqualityengland.co.uk) for further context.
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 as the last update timestamp is in the future (2026-06-16).
