Ozone plays a crucial role in atmospheric chemistry, forming naturally in the stratosphere and at ground level through sunlight and precursor pollutants. While essential, ground-level ozone poses risks to human health and ecosystems. A University of Galway-led study explored the drivers of ozone pollution in Ireland, highlighting the influence of meteorology and transboundary emissions. Using long-term data and advanced modelling, researchers found that rural and coastal areas experience higher ozone levels than urban zones, though urban ozone is rising in Ireland and at a Global level due to declining NOₓ emissions. The study identifies methane as the main reactive carbon precursor to Irish ground-level ozone. The findings provide policy actors with evidence that supports the use of high-resolution modelling to understand ozone trends and recommends increased public awareness using educational campaigns.
