Two Advanced Grants for ETH

Ulrike Lohmann, a professor for Experimental Atmospheric Physics, focuses in her research on the role of aerosol particles and clouds in the climate system. Her specific interest is to gain a better understanding of the cloud microphysical processes leading to precipitation in clouds involving ice. The ERC advanced grant will tackle this problem by injecting ice nucleating particles from a drone into supercooled stratus clouds to investigate related microphysical changes, including fundamental aspects of ice formation and growth. The project combines a multi-dimensional approach of targeted cloud seeding with a focus on wintertime stratus clouds in Switzerland. The researchers will use the analysis of their cloud seeding events to validate and improve the cloud microphysics scheme in the Swiss weather forecast model and ultimately precipitation forecasts. In addition to pioneering of a new methodology of using drones for cloud seeding, their results will be important to quantify consequences of artificial weather modification and climate interventions.

Frank Schimmelfennig is Professor of European Politics at the Department of Humanities and Social Sciences. His research group studies the politics and dynamics of European integration. The ERC project on ‘Bordering Europe: Boundary Formation in European Integration’ starts from the observation that the European Union’s recent crises – from the euro crisis to the Corona pandemic – have originated at and put at stake the borders of the EU. Moreover, European integration is under pressure from geopolitical shifts in its neighbourhood and beyond. Yet current theories of European integration focus almost exclusively on internal developments and boundaries between the member states. The ERC project therefore aims to develop and test a novel ‘bordering theory’, which explains how external boundary developments affect integration. It examines how boundary configurations and cross-border transactions shape the internal political developments of the EU, and how boundary policies are negotiated in the EU.
