Major Airport Noise Levels (Lden, Lday, Lnight) from UK Data

OpenDataNI provides noise level metrics for major UK airports, including Belfast International Airport. The data includes standard acoustic indicators such as Lden, Lday, Lnight, Levening, and LAeq,16hr. It was last updated on 2026-03-18 and is available in multiple formats including CSV, JSON, and geospatial files.

Use Cases

• Modeling noise pollution exposure based on Lden, Lday, and Lnight metrics.
• Assessing nighttime noise impact on residential areas based on Lnight values.
• Conducting geospatial analysis of airport noise contours using the provided SHP and GEOJSON files.
• Comparing day, evening, and night noise levels (Lday, Levening, Lnight) for regulatory compliance studies.

Strengths

• Data includes multiple standard noise metrics (Lden, Lday, Lnight, Levening, LAeq,16hr).
• Available in multiple formats including CSV, JSON, and geospatial formats (SHP, GEOJSON, KML).
• Published under the OGL-UK-3.0 license, allowing for 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.
• Description metadata is limited; actual data quality requires manual inspection after download.
