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 Union's Horizon 2020 programme, climate modelling groups and weather services have teamed up 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 global storm- and eddy resolving weather and climate simulations on the upcoming (pre-)Exascale supercomputers, we provide a technology for better and more detailed climate-related risk assessments on a local level.

The 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 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.

HPDA & Visualisation training 2022 successfully completed

In this third and final ESiWACE2 online training on High Performance Data Analytics (HPDA) and Visualisation, more than 50 registered participants from 17 countries learned the ropes of HPDA and visualisation using Ophidia, PyOphidia and ParaView.
