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

Lden, Lnight, Lday, Levening, and LAeq,16hr noise metrics for major UK airports, including Belfast International Airport. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license and was last updated in March 2026. It is available in multiple geospatial and tabular formats, including SHP, GEOJSON, KML, and CSV.

Use Cases

• Modeling noise exposure for residential areas based on Lden, Lnight, and Lday metrics.
• Conducting environmental impact assessments for airport operations using LAeq,16hr data.
• Creating geospatial visualizations of noise contours around airports using the provided SHP or KML files.
• Analyzing diurnal noise patterns by comparing day, evening, and night (Lden) sound levels.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq,16hr) for analysis.
• Data is available in several interoperable formats, including geospatial (SHP, GEOJSON, KML) and tabular (CSV, JSON).
• Has a clear open license (OGL-UK-3.0) permitting reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial/temporal coverage are unknown, which may limit suitability assessment.
