Research Interests

Clouds play a key role in the climate system: driven by radiation, clouds power the hydrological cycle as well as global atmospheric dynamics and fundamentally affect the global radiation balance. The representation of clouds in models is the dominant source of uncertainty in current climate predictions. Our research group seeks to understand, quantify and model the physical processes driving clouds and their response to man-made perturbations in terms of aerosols (small particles in the air that are the nuclei of cloud droplets) and global warming. We employ a broad range of tools to address our science objectives, ranging from modelling, theory and/or a broad range of earth observations, from satellite and ground based remote sensing to aircraft measurement campaigns – and increasingly also machine learning. Details of the project will be developed jointly with the student.
