Air pollution can have unacceptable impacts on the natural environment. In particular, elevated atmospheric nitrogen deposition can result in changes to the plant communities of natural and seminatural ecosystems, resulting in decreases in plant biodiversity. This project developed empirical critical loads of nutrient nitrogen for 17 Annex I habitats. The project analysis suggests that habitats within the Atlantic biogeographic region have critical loads at the low end or lower than existing UNECE recommended ranges for European habitats.

Changing population trends, growing urbanisation and associated economic development increase pressure on our water resources. This project investigates the feasibility of using space-based observations of gravitational anomalies, obtained by NASA’s Gravity Recovery and Climate Experiment (GRACE), to assess groundwater variations at a regional level across the island of Ireland. The report fully documents ways of accessing, processing and visualising GRACE gravitational anomaly data, and outlines a means to integrate data from NASA’s land surface model with data from the EPA’s HydroNet groundwater well network.

The project successfully established the AEROSOURCE network, comprising three sophisticated aerosol mass spectrometer nodes positioned in strategic locations: Carnsore Point (regional background), Dublin (urban environment) and Mace Head (marine background). It enhanced the National Transboundary Air Pollution Network with near real-time aerosol chemical speciation (including organic matter) and source apportionment capabilities.

Research was conducted to assess the contribution of diesel vehicle emissions to the concentrations of PM2.5 in Dublin. The major source identified was solid fuel burning, contributing 46-50% of the total mass recorded. The 2nd largest contributor at a roadside site was diesel vehicle emissions (22%) followed closely by road dust (19%). The 2nd largest source at a suburban site was soil (20%) followed closely by sea spray (14%).

The Atmospheric Composition and Climate Change (AC3) network is an established national research and monitoring infrastructure developed incrementally. It monitors greenhouse gases, short-lived climate forcers, and aerosol chemical and physical characteristics in line with best practice from pan-European and global monitoring programmes. This fellowship has enabled and sustained scientific operations for a national monitoring network.

The Atmospheric Composition and Climate Change network is a valuable established national research and monitoring infrastructure. This fellowship has enabled and sustained scientific work on a national monitoring network. Infrastructure has been continually developed over the course of the fellowship that will facilitate long-term sustainable measurements.

This project aimed to inform efforts at combating climate change as a core national priority in the pursuit of a sustainable, low carbon economy in compliance with international obligations to reduce emissions of greenhouse gases (GHGs) and air pollutants and increase soil organic carbon (SOC) sequestration.

The power of remote sensing lies in its ability to automatically and continuously characterise parts of the atmosphere that can be far away from the sensor, e.g. at high altitudes from the ground in the case of this study. This fellowship focused on continuous high-resolution (vertical and temporal) profiling of the atmosphere over Mace Head Atmospheric Research Station using active and passive ground-based remote sensing techniques.
In this research project, the contribution of residential solid fuel burning to ambient levels of wintertime PM2.5 was determined in the towns of Killarney, Enniscorthy and Birr. The results show that the burning of peat, coal and wood for home heating is by far the largest source of PM2.5 air pollution in these locations., June 2020

This research developed a state-of-the-art integrated model system to map emissions for Ireland’s emission inventories of air pollutants and greenhouse gases. Based on a variety of spatial and statistical data, the MapEIre model produced detailed spatial emissions at a resolution of 1 km × 1 km.

This fellowship project supports extensive research efforts on particulate matter (PM) studies in Ireland and at Mace Head station, particularly for building a knowledge base and establishing and sustaining long-term measurement series at the station.

This fellowship enabled and sustained scientific operations at Mace Head Atmospheric Research Station. The advanced method of dual carbon isotope analysis will allow better identification of natural and anthropogenic source contributions, which is essential for quantifying human-induced global climate change.

Reforms to the European Union Emissions Trading Scheme (EU ETS) in Phase IV create a potential risk to industrial competitiveness in the power generation and heavy industry sectors through increased costs. The costs may be directly linked to greenhouse gas (GHG) emissions via European Union Allowances (EUAs) or may be indirect via increased energy costs.

Air pollution is the primary environmental cause of premature death in the EU (EC, 2013) and the most problematic pollutants across Europe have consistently been oxides of nitrogen [e.g. nitrogen dioxide (NO2)], particulate matter (e.g. PM10, PM2.5) and ozone (O3).
