The Earth’s radiation budget and future climate change are intricately linked to clouds and aerosols. Efforts to accurately predict future climate, and socially adopt to it, are hampered by our limited understanding of how aerosols, clouds, circulation and climate interact. Our main research interest is in trying to better understand the role of clouds and aerosols in the climate system. In order to do so we mostly use numerical models of different scales (from the single cloud scale to the global scale) and observations.
