Projects:
Digital Earth
In the age of digitization, significant advances in Earth system understanding can be achieved through better integration of data and knowledge from different Earth science disciplines and earth compartments into model-driven earth system analysis. The progress and improvement strongly depends on our capabilities of dealing with fast growing multi-parameter data and on our effort employing Data Science methods, adapting new algorithms and developing workflows tailored to . . . . . more
ESM - Earth System Modelling
The main objective of the project is to develop, evaluate and apply a world-leading Earth system modelling infrastructure - leading into an Earth System Simulator - to provide solutions to grand challenges faced by the Earth and environmental sciences. The project aims to enable the investigation of problems in an integrated manner considering interactions between different Earth system compartments and across scales - from local to global scales, and from weather time scales to millennia and beyond. More information about Digital Earth can be found at: https://www.esm-project.net/
Both, Digital Earth and ESM are Future Research Projects of the Helmholtz Association. More Information about the program and the Helmholtz Initiative and Networking Fund can be found HERE.
