Abstract I will talk about the new knowledge we as a scientific community are gaining to better understand the atmospheric impacts of pollutants released into all atmospheric layers due to rocket launches and ablative re-entry of discarded spacecraft. Specifically, I will focus on the emission inventory development and atmospheric chemistry transport modelling being carried out in my group to quantify the magnitude and trends in air pollutant emissions and the impacts on global climate and the protective ozone layer

Eloise Marais is Professor of Atmospheric Chemistry and Air Quality at UCL. There, she leads a research group that combines data from multiple platforms (models, aircraft, satellites, lab and field measurements) to better understand the influence of humans on atmospheric chemistry, air quality, and climate from urban to regional to global scales. A key focus of her research is on the atmospheric impact of pollutants produced by spacecraft launches and re-entries.
