Research 390: Nitrogen–Sulfur Critical Loads: Assessment of the Impacts of Air Pollution on Habitats

Authors: Julian Aherne, Kayla Wilkins and Hazel Cathcart, September 2021

Year: 2021

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.

Research 387: GRACE Monitoring of Groundwater over Ireland – A Feasibility Study

Authors: Michael Geever, Eve Daly and Aaron Golden, August 2021

Year: 2021

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.

Research 385: Air Pollution Sources in Ireland

Authors: Jurgita Ovadnevaite, Chunshui Lin, Matteo Rinaldi, Darius Ceburnis, Paul Buckley, LizColeman, Maria Cristina Facchini, John Wenger and Colin O’Dowd, July 2021

Year: 2021

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 367: Particulate Matter from Diesel Vehicles: Emissions and Exposure

Authors: Meabh Gallagher, Bidroha Basu, Bidisha Ghosh, Md. Saniul Alam, Laurence Gill, BalzKamber and Aonghus McNabola, February 2021

Year: 2021

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%).

Research 365: Developing Ireland’s Greenhouse Gas and Transboundary Air Pollution Monitoring Network

Authors: Damien Martin and Colin O’Dowd, January 2021

Year: 2021

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.

Research 357: Ireland’s Atmospheric Composition and Climate Change Network

Authors: Damien Martin and Colin O’Dowd, November 2020

Year: 2020

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.

Research 325: Sourcing and Assessing Agricultural Activity Data for Modelling and National Estimates of Greenhouse Gases and Air Pollutants

Author: Mohammad Ibrahim Khalil, July 2020

Year: 2020

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.

Research 319: Remote Sensing of Aerosols, Clouds and Wind at Mace Head Atmospheric Research Station

Authors: Jana Preißler and Colin O’Dowd, July 2020

Year: 2020

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.

Research 318: Source Apportionment of Particulate Matter in Urban and Rural Residential Areas of Ireland (SAPPHIRE)

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

Research 317: MapEIre: National Mapping of Greenhouse Gas and Non-greenhouse Gas Emissions Sources Project.

Authors: Ole-Kenneth Nielsen, Marlene S. Plejdrup, Henrik G. Bruun, Steen Gyldenkærne and Jesper H. Christensen, May 2020

Year: 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.

Research 276: EU ETS and Competitiveness of Irish Industry

Authors: Celine McInerney, Ellen O’Connor, Bernadette Power, Paul Deane and Tom McDermott , May 2019

Year: 2019

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.
