Lnight noise level data from strategic noise mapping for European airports with over 50,000 annual movements and agglomerations of at least 250,000 people. This dataset is produced by the Government Digital Service to meet the requirements of the Environmental Noise Directive (2002/49/EC). The Lnight metric represents the annual average noise level during night hours, defined as 2300 to 0700.
Use Cases
- Modeling population exposure to night-time aviation noise based on the Lnight metric.
- Assessing compliance with the EU Environmental Noise Directive for major airports.
- Analyzing noise pollution patterns around airports and large urban agglomerations.
- Supporting environmental impact assessments for airport infrastructure projects.
Strengths
- Data is produced under a binding EU directive (2002/49/EC), ensuring a standardized methodology.
- Focuses on major noise sources, covering airports with over 50,000 movements and agglomerations over 250,000 people.
- Uses a specific, regulated noise metric (Lnight) for the night period (2300-0700).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file formats are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
