Sandwell Air Quality Annual Mean Pollutant Concentrations from Monitoring Sites

Annual mean concentrations for nitrogen dioxide, particulate matter, sulphur dioxide, and ozone from a network of automatic and non-automatic monitoring sites in the Sandwell borough. The data is fully ratified and compared to National Air Quality Objectives to determine exceedances, with previous years' data included where available. Sandwell Metropolitan Borough Council maintains this dataset as part of its duty under the Environment Act 1995 to review and assess air quality.

Use Cases

• Assess compliance with National Air Quality Objectives based on annual mean pollutant concentrations.
• Analyze long-term trends in key air pollutants like nitrogen dioxide and particulate matter.
• Identify areas of exceedance for targeted air quality management based on geospatial site locations.
• Model population exposure to air pollution using the network of monitoring sites.

Strengths

• Data is fully ratified, indicating a quality assurance process.
• Includes annual mean concentrations for multiple key pollutants: nitrogen dioxide, particulate matter, sulphur dioxide, and ozone.
• Contains geospatial location data for monitoring sites.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the last update timestamp is in the future (2026-07-08).
