Major Airport Noise Levels (Lden, Lnight, Lday) for UK Airports

Noise exposure data for major UK airports, including Belfast International Airport, measured using standard metrics like Lden, Lnight, Lday, Levening, and LAeq,16hr. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license and was last updated on 2026-03-18. Available formats include JSON, KML, CSV, SHP, and GEOJSON.

Use Cases

• Modeling community noise exposure based on Lden and Lnight metrics.
• Analyzing spatial distribution of airport noise using the provided geospatial formats (KML, SHP, GEOJSON).
• Comparing daytime (Lday) versus nighttime (Lnight) noise levels for regulatory compliance studies.
• Assessing long-term noise trends around specific airports like Belfast International.

Strengths

• Data is provided in multiple geospatial and tabular formats (JSON, KML, CSV, SHP, GEOJSON, HTML).
• Uses standard environmental noise indicators (Lden, Lnight, Lday, Levening, LAeq,16hr).
• Published under the permissive OGL-UK-3.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
