Co-funded by the European High Performance Computing Joint Undertaking (EuroHPC JU) under the powers delegated by the European Commission (EC)—with half of the budget provided by the home countries of the partners' institutions—the 3rd phase of the Centre of Excellence in Simulation of Weather and Climate in Europe, ESiWACE3, focuses on supporting the weather and climate modelling community to reach a higher readiness level regarding exascale supercomputing and foster knowledge transfer between the different Earth System modelling centres and teams across Europe. At this aim, climate modelling groups have teamed up with High-Performance Computing (HPC) centres and partners from the technology industry to improve all aspects of the weather and climate modelling workflow.
Led by the Barcelona Supercomputing Center-Centro Nacional de Supercomputación (BSC-CNS), the project will focus on three main goals that are essential to prepare existing operational weather and climate prediction systems for the exascale era:
1. The transfer and establishment of knowledge and technology for efficient and scalable simulations of weather and climate across the Earth System modelling community in Europe;
2. Closing common technology gaps in the knowledge and toolbox for high-resolution Earth System modelling via joint developments across the European community;
3. Serving as a sustainable community hub for training, communication, and dissemination of high-performance computing for weather and climate modelling in Europe.
ESiWACE3 will bring the various approaches to address these challenges from the different modelling groups together to transfer knowledge across the weather and climate domain, generate synergies between the local efforts, provide targeted support to modelling groups via customised high-performance computing services, and provide training to educate the next generation of researchers.
Within this context, we pursue to:
- Increase efficiency of weather and climate simulations on state-of-the-art supercomputers;
- Design tools to close technology gaps for high-performance computing;
- Develop tools to tackle the data challenge of high-resolution weather and climate modelling;
- Support the broader community of weather and climate modelling in the use of state-of-the-art supercomputers via targeted services;
- Support the wider community of weather and climate modelling in the use of state-of-the-art supercomputers via training and capacity building;
- Build a well-connected and inclusive community for high-resolution Earth System modelling across Earth system science and HPC, and establish connections and knowledge transfer between existing European initiatives.
