Global modelling of chemical processes

Formic Acid at surface

Research

We decipher the complex multiphase chemical transformations that affect atmospheric composition and explore their role in the Earth System.

Atmospheric Oxidation Capacity

We investigate the global impact of organic and nitrogen compounds degradation on the main tropospheric oxidants, ozone and hydroxyl. We are on a quest to identify overlooked chemical drivers in order to resolve model biases of the predicted global distributions. We are especially interested in the recycling of hydroxyl radical and its buffering strength against perturbations.

Secondary Organic Aerosols

We develop mechanisms that yield organic aerosol precursors in collaboration with our experimental and theoretical groups. We focus in particular on the multiphase oxidation of organic compounds leading to highly oxygenated molecules. We assess their global importance for aerosol nucleation and growth.

Atmospheric Composition in the Earth System

We explore the chemical couplings of the troposphere with the stratosphere, the terrestrial vegetation and the ocean. We investigate the impact of exchanges and multiphase reactions which affect hydroxyl, ozone and aerosol formation.
