Digital Twin of Earth system for Cryosphere, Land surface and related interactions

TerraDT, coordinated by CSC–IT Center for Science, Finland, will enhance the Destination Earth (DestinE) infrastructure by developing a Digital Twin of the Earth system for the cryosphere, land surface and related interactions. TerraDT improves the descriptions of Earth system components in the DestinE climate Digital Twins (DTs) for land ice, sea ice, aerosols and land surface. It is based on a modular infrastructure with a coupling interface that enables adding new components or AI/ML-based emulators. TerraDT also develops impact models linked to the cryosphere and land surface to provide user-relevant information with interactive capabilities and enable their full integration to the DestinE framework. TerraDT will improve the reliability and relevance of the climate projections and impact assessments of DestinE, which is critical for guiding adaptation and mitigation actions.

The role of VTT in the project is to integrate forest growth and productivity models with the land surface models included in the Climate DT. We will also develop integration of novel remote sensing data such as hyperspectral imaging and chlorophyll fluorescence measurements into the process-based model chain.
