Technical Challenges and Solutions in Building a Pre-Exascale Climate Adaptation Digital Twin
DescriptionDestination Earth Climate Change Adaptation Digital Twin (Climate DT) is a new type of climate information system that can be used to guide climate change adaptation efforts. The Climate DT harnesses two Earth-system models (ESMs), ICON and IFS-FESOM/NEMO. The models are adapted to two pre-exascale EuroHPC systems: LUMI that is in operation in Kajaani, Finland, and Mare Nostrum 5 that will be available during 2023 in Barcelona, Spain. The Climate DT introduces the idea of a generic state vector (GSV), which is evolved by the ESMs and streamed to applications. This novel approach enables the ESMs to work at an unprecedented scale and thus improves the fidelity of the climate information as well as its relevance for the users. Use cases from five impact sectors, as well as a framework for quality assessment and uncertainty quantification, are implemented within Climate DT as applications that operate on the streamed GSV. This presentation will discuss technical challenges and corresponding solutions in developing the Climate DT, connected to adapting the models to the new HPC systems, developing the novel workflow, and handling the vast amount of data produced by the models.
