England Airport Noise Metrics On 10-Meter Grid

England's strategic noise mapping data for airports, produced by the Department for Environment, Food and Rural Affairs in 2022. It contains modelled annual average noise levels on a 10-meter grid at a 4-meter receptor height. The data meets the requirements of the Environmental Noise (England) Regulations 2006.

Use Cases

• Model community noise exposure by analyzing the day-evening-night level (Lden) and night level (Lnight) metrics across the geospatial grid.
• Assess daytime noise impact for regulatory compliance using the 16-hour equivalent continuous level (LAeq,16h) and day level (Lday) indicators.
• Evaluate evening-specific noise disturbances by examining the evening level (Leve) data for the 19:00-23:00 period.
• Perform spatial analysis of noise contours by joining grid-level Lden and Lnight values with geographic boundary datasets.

Strengths

• Noise levels are modelled on a detailed 10-meter grid.
• Includes five standardized acoustic metrics (Lden, LAeq,16h, Lday, Leve, Lnight) for comprehensive assessment.
• Data is a product of the 2022 strategic noise mapping analysis, providing a recent snapshot.

Limitations

• Specific row count, column details, and sample size are unknown.
• Modelling thresholds vary by airport as data is provided by different competent authorities, limiting consistency.
• The temporal coverage is limited to the annual averages from the 2022 mapping round.
