Maruhashi, J. (author), Mertens, M. (author), Grewe, V. (author), Dedoussi, I.C. (author)Flight altitude is relevant to the climate effects resulting from aircraft emissions. Other research has shown that flying higher within the troposphere leads to larger warming from O <sub>3</sub> production. Aircraft NO <sub>x</sub> emissions are of particular interest, as they lead to warming via the short-term production of O <sub>3</sub>,...journal article 2024

Rao, P.V. (author), Dwight, R.P. (author), Singh, D. (author), Maruhashi, J. (author), Dedoussi, I.C. (author), Grewe, V. (author), Frömming, Christine (author)While efforts have been made to curb CO2 emissions from aviation, the more uncertain non-CO2 effects that contribute about two-thirds to the warming in terms of radiative forcing (RF), still require attention. The most important non-CO2 effects include persistent line-shaped contrails, contrail-induced cirrus clouds and nitrogen oxide (NOx)...conference paper 2023

Maruhashi, J. (author), Mertens, Mariano (author), Grewe, V. (author), Dedoussi, I.C. (author)Aviation’s contribution to anthropogenic global warming is estimated to be between 3 – 5% [1]. This assessment comprises two contributions: the well understood atmospheric impact of carbon dioxide (CO2) and the more uncertain non-CO2 effects. The latter pertain to persistent contrails and pollutants like nitrogen oxides (NOx), water vapor (H2O),...abstract 2023

Henneman, Lucas R. F. (author), Choirat, Christine (author), Dedoussi, I.C. (author), Dominici, Francesca (author), Roberts, Jessica (author), Zigler, Corwin M. (author)Policy-makers seeking to limit the impact of coal electricity-generating units (EGUs, also known as power plants) on air quality and climate justify regulations by quantifying the health burden attributable to exposure from these sources. We defined “coal PM2.5” as fine particulate matter associated with coal EGU sulfur dioxide emissions and...journal article 2023

Maruhashi, J. (author), Grewe, V. (author), Frömming, Christine (author), Jöckel, Patrick (author), Dedoussi, I.C. (author)Aviation produces a net climate warming contribution that comprises multiple forcing terms of mixed sign. Aircraft NOx emissions are associated with both warming and cooling terms, with the short-term increase in O3 induced by NOx emissions being the dominant warming effect. The uncertainty associated with the magnitude of this climate forcer...journal article 2023

Domingos de Azevedo Quadros, F. (author), van Loo, Marijn (author), Snellen, M. (author), Dedoussi, I.C. (author)Excess nitrogen deposition from anthropogenic sources of atmospheric emissions, such as agriculture and transportation, can have negative effects on natural environments. Designing effective conservation efforts requires knowledge of the contribution of individual sectors. This study utilizes a global atmospheric chemistry-transport model to...journal article 2023

Domingos de Azevedo Quadros, F. (author), Snellen, M. (author), Dedoussi, I.C. (author)Aircraft emitted oxides of nitrogen (NOx) contribute both to climate change and air quality degradation. The trend of higher gas temperatures, caused by engine design choices seeking lower fuel consumption and achieve more complete combustion, has the adverse effect of increasing NOx formation, which might however be compensated by improved...conference paper 2022

Maruhashi, J. (author), Grewe, V. (author), Frömming, Christine (author), Jöckel, Patrick (author), Dedoussi, I.C. (author)The resilient growth of air travel demands a comprehensive understanding of the climate effects from aviation emissions. The current level of knowledge of the environmental repercussions of CO2 emissions is considerably higher than that of non-CO2 emissions, which includes nitrogen oxides (NOx), sulfur oxides (SOx), other aerosols like black...abstract 2022

Roosenbrand, E.J. (author), Sun, Junzi (author), Dedoussi, I.C. (author), Stam, D.M. (author), Hoekstra, J.M. (author)Sustainability is the biggest challenge facing the aerospace industry today. With the global number of flights expected to rise, the climate impact of aviation will continue to increase. Current research states that the rerouting of aircraft through wind-optimisation for the purpose of fuel usage minimisation and emission reduction is an...conference paper 2022

Radhakrishnan, Kaushik (author), Deck, K.T. (author), Proesmans, P. (author), Linke, Florian (author), Yin, F. (author), Grewe, V. (author), Vos, Roelof (author), Lührs, Benjamin (author), Niklaβ, Malte (author), Dedoussi, I.C. (author)The aircraft’s environmental performance on fleet level is so far completely decoupled from the design process. The climate impact from aviation arising from non-CO2 effects are largely independent from CO2 emissions, but rather depend on the atmospheric state. Previously complex climate-chemistry models were used to evaluate the non-CO2...conference paper 2022

As land cover is continuously evolving, influenced by anthropogenic and other factors, the availability of temporally varying land cover data sets of large spatial domains is integral to...journal article 2022

Domingos de Azevedo Quadros, F. (author), Snellen, M. (author), Sun, Junzi (author), Dedoussi, I.C. (author)Aviation is a growing source of atmospheric emissions impacting the Earth’s climate and air quality. Comprehensive assessments of the environmental impact of this industry require up-to-date, spatially resolved, and speciated emissions inventories. We develop and evaluate the first such estimate of global emissions from aircraft operations for...journal article 2022

(author)Depletion of stratospheric ozone, and the associated increase in population exposure to UV radiation, is an environmental consequence of high-altitude, supersonic aviation. Assessments of the impacts of emissions from subsonic aircraft – which fly at lower altitudes – have instead shown that they produce a net increase, rather than decrease,...journal article 2022

Sun, Junzi (author), Dedoussi, I.C. (author)In this paper, we propose a data-driven approach that estimates cruise-level flight emissions over Europe using OpenSky ADS-B data and OpenAP emission models. Flight information, including position, altitude, speed, and the vertical rate are obtained from the OpenSky historical database, gathered at a sample rate of 15 s. Emissions from each...journal article 2021

It is important as a transport sector for connections on and between continents. Nevertheless, aviation also contributes to anthropogenic climate change. The e_ects are usually divided in CO2 and non-CO2 e_ects and therefore not only CO2 emissions but also other emissions (e.g., NOx, water...abstract 2021

Domingos de Azevedo Quadros, F. (author), Dedoussi, I.C. (author)Emissions from civil aviation traffic degrade air quality, causing human health problems that have been estimated to result in ~16 000 premature deaths per year globally, potentially making the cost to society of the air quality impacts even greater than the cost of the climate impact of these emissions. Previous studies have indicated that...abstract 2020
