The project “DynamicEarth” is directed towards the mechanistic understanding of three and four dimensional Earth System processes incorporating the essential approaches fundamental to modern science: experiment, observation and simulation. The focus is put on integrating (data-driven) observations from space into model-driven parameters of earth system processes in close feedback loops. An integrated approach is investigated, which is in particular designed to assimilating data into models on one hand, and regularization of data based on knowledge provided by models on the other hand. The research envisioned in this project is exemplified by the observation, modeling, and understanding of two Earth System processes that have immediate as well as long-term influence on humanity: the mechanics of active volcanoes and earthquakes, e.g., posing a threat for cities, and the dynamics of glaciers and polar ice caps indicating long-term changes of our climate. Methodologically, the proposed research integrates space-borne Radar Earth Observation techniques (represented by Lehrstuhl für Methodik der Fernerkundung, ESPACE-GS) with numerical modeling of Earth System processes on the surface and in the interior of our planet – like glacial flow (represented by Fachgebiet Computational Mechanics and Lehrstuhl für Statik, CeSIM-GS). Throughout the project different scales of phenomena are investigated, from individual buildings to entire volcanoes.
