Belfast Agglomeration Airport Noise Levels in Lden, Lnight, Lday, and Levening Metrics

Noise level data for the George Best Belfast City Airport within the Belfast Agglomeration, an urban area with a population exceeding 100,000 and a density of at least 500 people per km². The dataset includes metrics such as Lden, Lnight, Lday, Levening, and LAeq,16hr, and is provided by OpenDataNI under the OGL-UK-3.0 license. It was last updated on 2026-03-18.

Use Cases

• Modeling community noise exposure based on Lden, Lnight, Lday, and Levening metrics.
• Assessing compliance with environmental noise regulations for airports in urban areas.
• Analyzing the spatial distribution of noise pollution from airport operations within a defined agglomeration.
• Correlating noise levels (LAeq,16hr) with population density data for health impact studies.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq,16hr) for detailed analysis.
• Geographic scope is clearly defined as the Belfast Agglomeration, an area with a population >100,000 and density >=500/km².
• Available in multiple geospatial and tabular formats (JSON, KML, CSV, SHP, GEOJSON, HTML).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Freshness should be verified as the last update date is in the future (2026-03-18).
