Surface ozone, a key component of tropospheric ozone, plays a significant role in atmospheric chemistry and air quality. As a secondary pollutant, formed through complex photochemical reactions involving precursor pollutants emitted from both natural and anthropogenic sources, surface ozone concentrations have garnered considerable attention due to their adverse effects on human health, vegetation, and ecosystems. Understanding the dynamics of surface ozone requires comprehensive studies integrating meteorological factors, emissions inventories, and atmospheric transport mechanisms. In this project, we aim to investigate the Trend of surface ozone concentrations, identify major contributing factors, and assess the effectiveness of mitigation strategies in improving air quality and safeguarding public health and environmental well-being. This research seeks to provide valuable insights into the complexities of surface ozone pollution. The overall concept of this project is to close the knowledge gap on contributions to ozone pollution in Ireland to deliver scientific support for the formation of effective mitigation strategies of national relevance.
