Louis Marelle is a research fellow at the French national center for scientific research (CNRS) and LATMOS, Paris, France. He obtained his Ph.D. in 2016 in atmospheric chemistry and physics. He studies atmospheric composition at the poles and its impacts on polar climates, aerosol-cloud interactions, and the human drivers of extreme precipitation. By developing state-of-the art regional models of the atmosphere and analysis of model ensembles, he is leading the effort in modelling aerosol-cloud interactions in the EU-CRiceS project, and in modelling ice formation on aerosols and aerosol impacts on extreme weather in the EU-CERTAINTY project. He has contributed to the Arctic Monitoring and Assessment Programme (AMAP) reports for short-lived climate forcers the Arctic and is a member of the scientific steering committee of CATCH (the cryosphere and atmospheric chemistry).
