PhD position in stratocumulus climate feedback

1 October 2025

We are recruiting a PhD student to investigate how global stratocumulus cloud cover responds to rising CO2 and sea surface temperatures, and the associated radiative feedback. The work will use an ensemble of global km-scale circulation model (ICON) simulations with varied turbulence, radiation coupling, and microphysics settings, constrained by satellite observations and data from an upcoming field campaign. The goal is to better constrain low cloud climate feedback, not the least in order to assess whether drastic stratocumulus changes are plausible, which would strongly affect global climate sensitivity. The project is part of the excellence cluster Climate, Climatic Change and Society II (CLICCS II).

Study on shortwave water vapor feedback

In a new study, CLICCS researcher Florian Römer and colleagues explore the clear-sky shortwave water vapor feedback, a lesser-known mechanism that amplifies warming by increasing the atmosphere’s ability to trap sunlight as water vapor levels rise. While the longwave (infrared) effects of water...
