LUC maps light pollution in Ireland

Logo - LUC'

Consultancy LUC has published an interactive map illustrating the darkest skies and areas of light pollution in County Mayo, Ireland.

The project was funded by The Heritage Council and shows how artificial lighting is impacting the county, highlighting areas with the darkest skies and areas impacted by light pollution. The map seeks to raise awareness of the growing issues and identifies where lighting improvements or adjustments could be made to minimise the impact.

Each pixel on the map represents the level of radiance (night lights) shining into the night sky. These have then been categorised into colour bands to distinguish between different light levels.

Across the UK over 80% of the population can no longer see the Milky Way from their homes due to light pollution and the figure is rising due to an increase in artificial lighting.
