NICEST2

NICEST-2 aims at i) improving the e-infrastructure to tackle these challenges in optimal conditions, with minimal waste of resources, and ii) setting up the building blocks for ESM workflows, which are to be deployed as a part of the Nordic European Open Science Cloud (EOSC), thereby realizing its full potential for the benefit of the Nordics.

Earth System Modeling research is essential to assess the drastic impacts of climate change and requires huge computing and storage resources that are still provided locally, e.g. at a national level. This hinders bit-replicability and makes it difficult for researchers to compare their developments and confidently validate the scientific results. In addition, the cost and expertise necessary for developing and improving Earth System Models often lead researchers to join large, international consortiums that do not necessarily focus on the Nordic region. Most Nordic countries participate in initiatives such as CMIP6 (Coupled Model Intercomparison Project Phase 6) and/or CORDEX (Coordinated Regional Climate Downscaling Experiment), but there is no coordination at the Nordic level.

For Open Science, reproducibility of earth system runs is as important as producing accurate and Findable Accessible Interoperable and Reusable (FAIR) climate data. The EuroHPC initiative is a unique opportunity for the Nordic countries to head towards a joint Climate Model Intercomparison Project (CMIP) participation, provided that all the necessary building blocks (containerization, workflow management, job orchestration, model diagnostics) for creating fully reproducible and efficient Earth System Model (ESM) workflows, as well as publishing FAIR climate data, are in place. In this context, the LUMI supercomputer will be the first shared pre-exascale system available in the Nordics through EuroHPC as of 2021.
