Major Airport Noise Levels in the UK, Including Day-Evening-Night Metrics

OpenDataNI provides noise level data for major UK airports, such as Belfast International Airport. The data includes metrics like Lden (day-evening-night level), Lnight, Lday, Levening, and LAeq,16hr. It was last updated on 2026-03-18 and is available in multiple formats including CSV, JSON, and geospatial files (KML, SHP, GEOJSON).

Use Cases

• Modeling noise exposure and its health impacts based on Lden and Lnight metrics.
• Mapping noise pollution contours around airports using the provided geospatial data formats.
• Assessing compliance with noise regulations by comparing Lday, Levening, and LAeq,16hr levels.
• Conducting time-series analysis of airport noise trends if temporal data is available.

Strengths

• Data is provided in multiple formats (JSON, KML, CSV, SHP, GEOJSON, HTML) for flexibility.
• Includes specific, standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq,16hr).
• Published under the OGL-UK-3.0 license, facilitating open use.

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.
• Data may reflect geographic bias inherent to the uk_data platform.
