Research ships
70 % of the earth's surface is covered by oceans. However, the great majority of measurment sites is located over land. Research ships allow to collect high resolution data over the oceans.

Research Interests
I am interested in (exo)planetary atmospheres, how they behave, and how different processes shape them. My PhD project focuses on the role of water vapour in the atmosphere: Despite being only a minor constituent of the terrestrial atmosphere, water vapour plays an important role in the Earth's climate; it influences radiative, convective, and dynamic processes. In a (locally or globally) moister atmosphere with a higher water vapour content, the influence of water vapour…

Whether it rains more over wet or over dry soils is set by the representation of convection
Whether an increase in soil moisture leads to an increase (positive feedback) or a decrease (negative feedback) of precipitation has long been debated. Positive feedbacks are of particular relevance for the climate system as they can amplify an existing perturbation, thus affecting the climate system on longer time scales. One difficulty in diagnosing the strength and sign of the feedback between soil…
