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. The big challenge today is quantifying the regional impacts and risks due to this warming, and assessing the effectiveness of potential measures to minimise climate change induced damages and deaths. 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 Union's Horizon 2020 programme, climate modeling groups and weather services have teamed up with high performance computing centers and partners from the IT industry to improve all aspects of the workflow of weather and climate modeling. By enabling global storm- and eddy resolving weather and climate simulations on the upcoming (pre-)Exascale supercomputers, we provide a technology for better and detailed climate-related risk assessments on a local level.

The project

We push forward a new generation of high resolution weather and climate models: with expertise in earth system modelling, software design and high performance computing, ESiWACE accompanies scientists on the path to exascale computers.

About us

Across disciplines and national borders: within ESiWACE about 20 European partners from science and HPC industry are working together. Who are we, which expertises do we have and what drives us? Participating scientific institutes, companies and people introduce themselves.


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