Leading and managing the project - We lead the ESiWACE3 Consortium, being responsible for providing effective technical, administrative, and contractual management to achieve the project objectives, as well as for establishing and maintaining internal communication within the consortium and effectively interacting with the EuroHPC JU and EU.

Improvement of climate and weather simulations - We help increase the efficiency of weather and climate simulations on state-of-the-art computers while designing and developing community tools to close technology gaps for HPC. We also participate in the data challenge of high-resolution weather and climate modelling by developing novel data layout concepts and recommendations for domain-specific data compression derived from community input. We also support the weather and climate modelling community via targeted services to enhance HPC applications.

Community engagement - We seek to build a well-connected and vibrant Earth system modelling community across Earth system sciences and HPC; simultaneously, we maximise engagement, ensuring gender equity and regional diversity. We aim to connect the HPC scientific community, technology providers, and users and share knowledge with other relevant European projects and initiatives.

The overarching ambition of the ESiWACE3 is to serve as a landing point for the European community of Earth system Modellers to cooperate, transfer and establish knowledge, expertise and technology for efficient and scalable weather and climate simulations. The project also aims to close common technology gaps in the knowledge and toolbox for high-resolution Earth System modelling via joint developments across the European community. It will serve as a sustainable community hub for training, communicating, and disseminating high-performance computing in Europe for weather and climate modelling.
