The International Max Planck Research School on Earth System Modelling (IMPRS-ESM), located in Hamburg, Germany, offers fellowships to outstanding students interested in interdisciplinary climate research. Our doctoral candidates contribute to the understanding of the Earth system through the application, evaluation and development of a spectrum of Earth system models at different levels of complexity and at various spatial and temporal scales. Emphasizing the physical system, the School encompasses the broader field of Earth sciences, including economics and social sciences.
