Our world is warming, what are the implications ?

The Earth's globally averaged near-surface air temperature is already about 1.1 degrees warmer than during the pre-industrial era, and we are certain that the warming will continue. We are confident that a new class of computer simulations, which will only become possible with the next generation of supercomputers, will enable a step change in the ability of our simulations to simulate climate change down to regional scales.

Funded by the European High-Performance Computing Joint Undertaking (EuroHPC U) 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, teams up climate modelling groups and weather services with high-performance computing centres and partners from the IT industry to improve all aspects of the workflow of weather and climate modelling. By enabling more detailed resolving weather and climate simulations on the upcoming exascale supercomputers, the required technology for better and more detailed climate-related risk assessments on a local level can be provided.

ESiWACE3 is coordinated and led by the Barcelona Supercomputing Center-Centro Nacional de Supercomputación (BSC-CNS).


Project

We are accelerating the development of a new generation of high-resolution weather and climate models: With expertise in earth system modelling, software design, and high-performance computing, ESiWACE is supporting scientists on the path to exascale computing.

About us

Across disciplines and national borders: Within ESiWACE, partners from the science and HPC industry work together. Who are we, which expertise do we have, and what drives us? Participating research institutions, universities, supercomputing centres, and private companies introduce themselves.

Services

For model developers, ESiWACE offers a number of services: Special software packages, public HPC services, and training programs to support the weather and climate community on the path to exascale computing.
