Louis Marelle - CNRS researcher - LATMOS, Paris, France

I am part of the TROPO (Troposphere: Pollution and Climate) research department at the LATMOS-IPSL laboratory.

I study the composition of the atmosphere, aerosols, clouds and precipitation. I am especially intested in the interactions between atmospheric composition and climate change in the polar regions.

My main research tools are regional atmospheric models, especially the WRF and WRF-Chem models. I co-develop and maintain an updated version of the WRF-Chem model well-tested in the arctic region, available on Github (link, updates in dev/ branches). I also use large model ensembles, and multiscale observations of the atmosphere such as surface in-situ measurements, aircraft and icebreaker campaigns, satellites, ground based remote sensing, and radiosondes.
