DestinE Climate Adaptation Digital Twin
The European Commission's Destination Earth (DestinE) programme aims to develop high precision digital twins (DT) of the Earth to support decision making in Europe. Climate change adaptation DT is one of the first DTs developed within DestinE.
Climate DT will design and implement a pre-exascale climate information system that can be used to assess impacts of climate change and different adaptation strategies at local and regional levels over multiple decades. The Climate DT harnesses two different kilometre-scale Earth-system models (ESMs) on Europe's most performant computing systems. It's goal is to provide information for adaptation use cases drawn from five climate impact sectors.
By disentangling the provision of climate information from its consumption, it creates the basis for an information system that can scale across an unlimited number of applications. The applications have access to all the data they need and achieve interactivity and new ways of co-design.
The ESMs will be adapted to two EuroHPC pre-exascale supercomputers: LUMI in Kajaani, Finland and MareNostrum 5 at the Barcelona Supercomputing Centre in Barcelona, Spain.
Use cases from different impact sectors will be implemented to the digital twin, providing information on:
- wind energy supply and demand
- wildfire risk and emissions
- river flows
- hydrometeorological extreme events
- heat stress in urban environments.
The Climate DT will be developed by an international team including 13 European organizations, based on the contract made with European Centre for Medium Range Weather Forecast (ECMWF). CSC coordinates the project and leads the work on the development of the digital infrastructure of the Climate DT. CSC also has a key role in deploying the Climate DT on LUMI supercomputer, that is hosted by CSC in Kajaani, Finland.
Destination Earth is a European Union funded initiative and is implemented by ECMWF, ESA, and EUMETSAT.
