Agglomeration Airport LAeq 16h: Noise Exposure Metrics for Belfast Area

Noise exposure data for the Belfast Agglomeration, an urban area exceeding 100,000 people with a density of at least 500 people per km2. The dataset includes metrics like LAeq,16hr, Lden, Lnight, Lday, and Levening, sourced from OpenDataNI and last updated on 2026-03-18. It covers the area around George Best Belfast City Airport, including Belfast, Newtownabbey, Carrickfergus, Lisburn, Holywood, Dundonald, Bangor, and Carryduff.

Use Cases

• Modeling noise pollution exposure based on LAeq,16hr and Lden metrics.
• Assessing nighttime noise impact (Lnight) on residential areas within the agglomeration.
• Comparing daytime (Lday) and evening (Levening) noise levels for policy analysis.
• Mapping geospatial noise distribution around George Best Belfast City Airport.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq,16hr).
• Geographic scope is clearly defined as the Belfast Agglomeration, an area with over 100,000 people.
• Available in multiple geospatial formats (KML, SHP, GEOJSON).
• License is clearly stated as OGL-UK-3.0.

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.
• Data may reflect geographic bias inherent to the uk_data platform, focusing on a specific UK agglomeration.
