Climate processes
Our research addresses physical climate processes in the context of anthropogenic perturbations to the Earth system as the underlying cause of climate change with an overall focus on the role of clouds and aerosols.

Earth Observation Data Group
The principal focus of EODG is the retrieval of atmospheric properties (e.g. temperature, pressure, trace gas concentrations, aerosol and cloud properties) from data gathered by Earth Observing satellites.

Geophysical and Astrophysical Fluid Dynamics
We study and research fluid-dynamical phenomena and processes that occur in geophysical and astrophysical systems, such as planetary atmospheres and oceans, stars, accretion disks and interstellar gas clouds.

Predictability of weather and climate
Predictions of weather and climate are inherently uncertain: initial conditions can never be known perfectly, and our weather and climate simulators are necessarily imperfect representations of the underlying laws of physics. Given this, how can we quanti
