What We Offer

Supporting Europe's Climate Modeling Community

ESiWACE3 supports the European modelling community by offering, via open calls, tailored advice, engineering time and/or help with implementing code modifications – free of charge – to weather and climate modelling groups. This is implemented via two categories of service projects:

Model Optimization, Acceleration, and HPC Exploitation
This service supports collaborative projects in which ESiWACE experts contribute both advice and engineering effort to applicants. Up to 6 person-months of support are available, distributed over one year.
