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

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

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
