Climate Digital Twin User Guide¶
The Destination Earth Climate Change Adaptation Digital Twin (Climate DT) sets up an operational simulation framework providing globally consistent high-resolution climate and impact-sector information, at spatial scales where many of the impacts of climate change and extreme events are observed. It allows to both simulate possible future evolutions of the climate system on multi-decadal timescales and assess “what-if” scenarios, supporting climate adaptation efforts across Europe.
The Climate DT combines global climate models, observations, and sector-specific applications, to deliver actionable insights from global and local scale, supporting applications in areas such as energy, hydrology, and wildfire risk.
ICON, IFS-FESOM, and IFS-NEMO provide a multi-model ensemble, with output harmonised onto a common HEALPix grid for fast and convenient data access.
Two types of simulations are being produced: global multi-decadal simulations describing the climate evolution under a specific future scenario for the period 1990-2049 and global storyline simulations that explore how extreme events, that occurred across the world during the period 2017-2025, would unfold in different climates.
The Climate DT is implemented by a partnership led by CSC - IT Center for Science in close collaboration with ECMWF, reflecting a broad European collaboration across operational prediction centers, supercomputing centers and academia.
Key capabilities¶
Kilometre-scale resolution: Enables realistic representation of local climate conditions and extreme events, globally.
Storyline simulations: Allow replaying events, that occurred worldwide, under past, present, and warmer climates to assess changing impacts.
Sector-specific applications: Translate climate information into actionable indicators for climate sensitive-sectors such as energy, hydrology, and wildfire risk.
Operational, quality-controlled workflow: Enable routine, reliable execution of simulations, data handling and evaluation, with consistent, validated outputs.

Simulation types¶
Multi-decadal simulations (1990–2049)
Three coupled atmosphere–ocean models run historical, projection, and control experiments at kilometre scale. See Multi-decadal Simulations.
Storyline simulations (IFS-FESOM, event-based)
Weather events, that occurred across the world during the period 2017-2025, replayed under past (~1950), present-day, and future (+2 °C) climate conditions using a spectral nudging approach. See Storyline Simulations.
User support¶
Users can contact the DestinE Climate DT team through the DestinE Platform support service. This serves as the central point for both technical and scientific inquiries.
