Climate and weather simulations powered by extreme scale computing
The Climate Change Adaptation Digital Twin (Climate Adaptation DT) and the Weather-Induced Extremes Digital Twin (Extremes DT), provide high quality simulations integrating Earth system information and the sectors most impacted by climate change and extreme weather events, exploring new forms of interactivity. The continuous component of the Extremes DT will provide global kilometre (km) - scale simulation capabilities to assess and predict environmental extremes within a time span of a few days. Both DTs include the impact sector elements to better respond to its users' needs. Powering the DTs, the Digital Twin Engine is the software infrastructure needed for extreme-scale simulations and data fusion, data handling and machine learning, adapted to exploit the capabilities of the EuroHPC supercomputers. It will also provide a flexible environment to operate the digital twins and trial on demand configurations adapted to specific applications.
