Agglomeration Airport Lden: Noise Exposure Metrics for Belfast Area

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

Use Cases

• Modeling community noise exposure based on Lden, Lnight, Lday, and Levening metrics.
• Assessing nighttime noise impact (Lnight) on urban populations near airports.
• Analyzing spatial noise distribution across the Belfast Agglomeration using geospatial formats.
• Comparing daytime (Lday) and 16-hour (LAeq,16hr) noise levels for regulatory compliance.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq,16hr).
• Data is available in multiple geospatial and tabular formats (JSON, KML, CSV, SHP, GEOJSON, HTML).
• Covers a defined urban agglomeration with a population exceeding 100,000 and a density >= 500/km².

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
