Abstract

Aircraft engines emit exhaust gases and particles into the atmosphere, impacting the environment, leading to air pollution and contributing to climate change. Our atmosphere is a complex system of coupled non-linear physical and chemical processes, and evolves over time. This means that for some pollutants, the same emissions mass will have different impacts depending on where and when it is emitted. In the quest to make aviation’s transition to sustainability as efficient and effective as possible, technological (aircraft & engine designs), operational, and regulatory interventions would need to account for these atmospheric systems and processes. This talk will cover a set of modeling approaches quantifying how atmospheric non-linearities affect the pollution and climate impacts from aircraft operations globally. We will also discuss novel data-driven ways of estimating real-world emissions of the aviation sector.
