Noise Round 4 Airport National (Lnight)
This dataset provides polygon-based noise contours for major airports in Ireland, produced under Round 4 of strategic noise mapping (2022), reflecting conditions during 2021. It covers the Lnight period, representing night-time noise exposure. Major airports are defined under the relevant regulations as those exceeding 50,000 air traffic movements annually. Published by the Environmental Protection Agency, the data supports assessment of environmental noise impact around large airports and forms part of Ireland's compliance with EU noise-mapping obligations for aviation infrastructure.”).This is a polygon dataset of the strategic noise mapping of major airports for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lnight period. Major airports were identified under the Regulaitons as those airports exceeding the threshold of 50,000 air…
