Aerosol Hygroscopic Growth in Marine and Continental Air
Bialek, Jakub (2013-09-24)Aerosol particulate matter contributes significantly to the global climate directly, through scattering and absorption of solar radiation, and indirectly, through changing cloud reflectance and cloud cover persistence. ... -
Air to sea gas exchange of CO2 in the north-east Atlantic Ocean
Keane-Brennan, Jevon (2011-12-08)Atmospheric carbon dioxide concentrations have been rising for the past 200 years, and started increasing at a faster rate during the last 60 years. The world's oceans act as a reservoir for large amounts of CO_2. How they ... -
Chemical nature and sources of particulate matter in urban areas
Lin, Chunshui (NUI Galway, 2019-05-07)Particulate matter (PM) air pollution adversely affects human health and can lead to premature deaths. The sources of air pollution, however, remain poorly understood especially in urban areas with intense human activities. ... -
Hygroscopicity of marine aerosol: Closure, long term observation and cloud condensation potential
Xu, Wei (NUI Galway, 2021-09-18)Marine aerosols have a profound impact on the global climate system by scattering solar radiation and serving as seeds for cloud formation. However, the marine aerosols in current models are still poorly represented and ... -
Modelling of accidental radioactive releases for Ireland
Joy, Cillian (NUI Galway, 2020-07-14)This study analyses the findings of dispersion modelling comparisons to improve the understanding of uncertainty and to influence the development of Ireland’s operational Nuclear Power Plant (NPP) accident emergency ... -
New Particle Formation in Marine Air
Monahan, Ciarán (2012-11-28)Marine aerosols contribute significantly to global climate directly by absorbing or scattering solar radiation, as well as indirectly by altering the reflectance and persistence of clouds. This work presents results of ... -
Regional Scale Modelling of Boundary Layer Ozone and Influences of Climate Change
Coleman, Mary (2013-02-20)Ozone is a major air quality parameter, a key player in atmospheric chemistry and instrumental in greenhouse gas forcing. Consequently, the subject of ozone pollution warrants significant consideration in the construction ... -
Remote sensing and in-situ characterisation of atmospheric aerosol pollution
Grigas, Tomas (2017-05-08)This work focuses on characterising various aspects of clean-background and polluted aerosol, mainly focusing on the North East Atlantic and Europe, using a range of in-situ and remote sensing instrumentation. Prior to ... -
Size and compositional dependent effects of marine aerosol on cloud condensation nuclei
Fossum, Kirsten (NUI Galway, 2018-12-06)This work investigates marine aerosol physico-chemical properties (e.g. size and chemistry) and its Cloud Condensation Nuclei (CCN) properties under natural background conditions. Black carbon (BC), a tracer for anthropogenic ... -
A study of black carbon and related measurements from Ireland's atmospheric composition and climate change network
Spohn, Teresa Kristine (NUI Galway, 2021-10-04)A national aethalometer network for monitoring black carbon was developed at three Irish regional stations (Mace Head, Malin Head, and Carnsore Point) as part of Ireland’s Atmospheric Composition and Climate Change (AC3) ...
