The world’s largest telescope – the Extremely Large Telescope (ELT) – is under construction in Chile. When it captures its “first light”, sometime in 2027 or 2028, Irish adaptive optics technology will be there to ensure it sees further and with greater clarity than any telescope in human history. A team of researchers at NUI Galway, led by Dr Nicholas Devaney (School of Physics), with expertise in adaptive optics are involved in the ELT project as part of a consortium also involving the Grenoble Institute for Planetary Sciences and Astrophysics and the National Institute of Astrophysics (INAF) in Italy. The consortium will design and manage the construction of an instrument on the ELT, called multi-conjugate adaptive optics relay (MAORY), which corrects image distortion due to atmosphere blurring. The NUIG team were invited to join the MAORY project based on their scientific reputation. Further information is available at the following link in the Irish Times Science News section.

Persistent organic pollutants (POPs) such as brominated flame retardants (BFRs) and perfluoroalkyl substances (PFASs) have been used extensively in applications such as electrical goods, soft furnishings and building insulation foam.   Dr Marie Coggins and Dr Nina Wemken from the School of Physics along with colleagues at the University of Birmingham have been working on the EPA research project, ELEVATE. ELEVATE measured selected BFRs and PFASs in indoor air and dust samples collected  from Irish homes, offices, cars and school classrooms. PFASs were also measured in samples of Irish tap water and bottled water. The same contaminants were measured in samples of human milk donated by Irish mothers. Project data facilitated an assessment of human exposure to these chemicals, allowing comparison with guidelines on human exposure developed by the European Food Safety Authority (EFSA), the revised European Union Drinking Water Directive. If you would like to learn more about POPs and Irish population exposure to POP-BFR and PFASs please read our project report at:  EPA Research Report 343

With the COVID-19 pandemic threatening workplace health and safety, Dr Marie Coggins, lecturer in exposure science at NUI Galway, writes about managing respirators and gloves in the fight against COVID-19.  Dr Coggins writes that over the next few weeks or months many of us will for the first time start using personal protective equipment or PPE. Personal protective equipment includes everything from disposable gloves and masks to ear plugs and gas tight suits. In the workplace we normally refer to PPE as a ‘last resort’ which should only be worn in circumstances when all other controls are unsuitable! Workers typically don’t like wearing PPE, its uncomfortable especially when worn for long periods of time. However, if worn and used correctly PPE can be an effective way of protecting workers. Further information about the article can be found at the following link: Health and Safety Review article by Dr. Marie Coggins.

Study published in Nature’s journal—Climate and Atmospheric Science New research published by NUI Galway’s Centre for Climate & Air Pollution Studies (C-CAPS) has shone light on the impact of clouds on climate change. The study has raised serious doubts of the likely impact of human-led interventions involving methods of cloud ‘brightening’ to counteract climate change. The new study has been published today in the Nature’s journal – Climate and Atmospheric Science. The study looks into clouds, with one of the most important types of elements in clouds thought to be sulphate.  Clouds, which are made of many droplets of condensed water on air particles, cool the climate by reflecting sunlight.  According to recent theories, more air pollution serves as condensation points for cloud droplets leading to more solar reflectance. This has led many to believe that fossil fuel emissions and other air pollutions may off-set global warming through cloud ’brightening’.  The Galway study found the addition of a small amount of sea-salt can dampen the effect of clouds becoming brighter as a result of increased sulphate in the atmosphere. Professor Colin O’Dowd, Director of C-CAPS and Established Chair of Atmospheric Physics, said: “The study backs up our previous thinking that sea-salt will factor out other substances and cause competition between potential nuclei influencing cloud reflectance. This means that recent theories that increased sulphate production can decrease the impact of climate change need to be reconsidered. Science is clearly pointing to the fact that carbon-based human activity is hurting our environment and there’s only one pathway to solve this - less fossil fuel and no interference with nature.” Researchers from NUI Galway joined the Spanish research vessel BIO Hesperides circling Antarctica’s Southern Ocean, known as the world’s cleanest laboratory.  The purpose of the expedition was to examine how the world’s atmosphere is functioning in a pollution free environment.  Lead author Dr Kirsten Fossum commented: “Clouds, particularly those overlying dark ocean surfaces, are the Earth’s key climate regulators, accounting for half of global reflectance. Pollution-induced changes to cloud reflectance, represent the single biggest uncertainty in predicting future climate change.  The large area covered and systematic evidence from the cruise to Antarctica provided the vast sample of clean air needed to conclusively support this study.” The study was funded by SFI through the MaREI centre and the Spanish Ministry of Economy and Competitiveness. The Antarctic cruise that led to this study was organised by the Institut de Ciéncies del Mar (CSIC), Barcelona, Catalonia, Spain. The researchers behind the study run the Mace Head Air Pollution and Climate Laboratory on the west coast of Ireland where they study the cleanest air in Europe and in the northern hemisphere. The team also recently released a unique smartphone app, known as StreamAir, it provides real-time weather forecasting and highlights key drivers of air pollution and climate disruption through air quality indications.

NUI Galway’s Centre for Climate and Air Pollution Studies (C-CAPS) has launched a new app to provide real-time forecasting data on atmospheric composition which will shine a light on the key drivers of climate change and air pollution and build on its internationally-recognised Mace Head Atmospheric Research station.  The C-CAPS’s Mace Head research centre in Connemara is one of the most important facilities for atmospheric composition observations globally and has been operating as far back as 1958. Executive Dean of Science and Engineering at NUI Galway, Professor Walter Gear, said: “We are very proud of the work we do here and its contribution to European health and to informing measures to protect our planet.  We are now adding this new app, StreamAIR, that will help to raise further awareness about air pollution and climate issues and their implications.” The Centre’s Director, Professor Colin O'Dowd said “The StreamAIR app is an extension of the Mace Head real-time data system, designed to fuse together real-time observation and forecast data on multiple platforms including mobile devices.” Through StreamAIR, NUI Galway and Mace Head not only provide current real-time data to a range of agencies and networks, the Facility has generated some of the most important long-term observation datasets of greenhouse gases (GHGs), such has carbon dioxide, methane, and ozone, and ozone depleting substances such as CFCs, along with Particulate Matter (PM), such as sulphate haze producing acid rain.   Mace Head is a member of a number of regional to global networks, contributing data and analysis to a wide range of atmospheric problems.  In particular, it is a World Meteorological Organisation (WMO) Global Atmosphere Watch (GAW) atmospheric composition and climate research station, and a European Monitoring and Evaluation Programme (EMEP) supersite with the aim of solving transboundary air pollution problems under the United Nations Convention on Long-range Transboundary Air Pollution (CLRTAP). Professor Colin O'Dowd added, “These long-term trends have underpinned successful policy development and intervention in acid rain and ozone depletion issues, but a lot of work still remains for GHG warming agents, driving global warming.  In fact, ozone is a double agent  - while it is critical to have (stratospheric) ozone high in the sky to protect us from the sun’s harmful UV rays, at the surface, (tropospheric) ozone is a harmful air pollutant, causing premature deaths and mortality, and also a short-term warming agent (i.e. its lifetime is much shorter that CO2) in terms of global warming. The StreamAIR app brings the polluting agents and global warming agents together into the palm of everybody’s hand, emphasising that both types of agents must be reduced through co-benefit observations, research, and policy development.” Dr Liz Coleman, the Principal Researcher on the project, funded by the SFI MaREI Energy, Climate and Marine research centre, said that the app has the potential to identify the sources of air pollution, as well as the toxicity level of air pollution episodes. This information can be combined with exposure data to better inform the public of the potential risks from a national level to a European scale. This enables users to protect their health by taking necessary precautions when a pollution event is forecasted on the app.    The app can be downloaded from the App Store.
