DT-HEAT+ is a digital twin designed to raise awareness and provide real-time intelligence on heat-related mortality—often overlooked despite being labelled by WHO as a “silent killer.” By combining AI-driven models with data from DestinE’s Digital Twin Components (EXTREMES and Climate), DT-HEAT+ delivers short-term mortality risk estimates and visualizations for city and regional authorities, urban planners, policymakers, and emergency services. Developed under a Letter of Intent between the National Observatory of Athens, ESA, ECMWF, and EUMETSAT, DT-HEAT+ strengthens DestinE’s goals by showcasing actionable digital twin solutions for climate resilience. Deployed in Athens and Prague as part of the EU-funded CARMINE project ( https://carmine-project.eu/ ), the service is designed for scalability across cities.

This tutorial introduces DT-HEAT+, a digital twin service that provides next-day predictions of heat-related mortality risk in urban areas. Developed by the National Observatory of Athens under the CARMINE project and awarded “Most Promising Proposal” by ESA’s DestinE Innovation Challenge, DT-HEAT+ combines deep learning with high-resolution Earth Observation and urban data. Now integrated into the Destination Earth platform through a partnership with ESA, ECMWF, and EUMETSAT, it supports city authorities, researchers, and emergency planners in assessing and managing heat risk. This video walks you through accessing the platform, interpreting the dashboard, and understanding how the tool supports climate resilience and public health preparedness.

TERMS AND CONDITIONS FOR DESTINATION EARTH (DestinE) USERS GRANTED UPGRADED ACCESS

The following Terms and Conditions are released by the European Commission and will be applicable for the initial stage of the operation of DestinE, which is still under development.

These Terms and Conditions constitute the entire agreement between the User and the European Commission regarding the use of the DestinE Services for Users Granted Upgraded Access and DestinE Data.

Please read them before registering for the upgraded access to DestinE.

ARTICLE 1: DEFINITIONS

For the purposes of these Terms and Conditions, the following definitions apply:

Academia and Research: Public academia and research teams from EU Member States or Associated Countries, provided that their domain of activity and intended usage are consistent with the objectives and scope of DestinE. On a case-by-case basis, this category may also include public academia and research teams from third countries, provided that their domain of activity and intended usage are consistent with the objectives and scope of DestinE and are not considered contrary to the Union’s strategic assets, interests, autonomy or security.

Associated Country: non-EU country associated to the Digital Europe Programme.

Destination Earth (DestinE): a flagship initiative of the European Commission to develop a highly accurate digital model of the Earth to model, monitor and simulate natural phenomena, hazards and the related human activities.

DestinE Core Service Platform (DestinE Platform): a user-friendly platform that provides a large number of users with evidence-based policy and decision-making tools, applications and services, based on an open, flexible, scalable and evolvable secure cloud-based architecture.

DestinE Data: Earth-system monitoring and prediction system output as provided by Destination Earth Digital Twins, as well as data that are generated by applications for Destination Earth and made available in the DestinE Data Lake.

DestinE Data Lake: a self-standing DestinE system component, interfacing with the Core Service Platform, Digital Twins and Digital Twin Engine, built from geographically distributed physical elements, that references and provides seamless access via GUIs or APIs to data in accordance with the DestinE Data Portfolio. The Data Lake supports near-data processing to maximize throughput and service scalability.

DestinE Data Portfolio: DestinE Data Portfolio is tailored to user needs and composed of federated data, Digital Twin data and DestinE user generated data with a specified and agreed lifecycle.

(DestinE) Digital Twin(s) (DT(s)): Highly accurate replicas of the Earth-system that simulate the system’s behaviour, allowing to monitor and predict environmental change, test scientific hypotheses and adaptation scenarios. DestinE’s DTs combine several cutting-edge Earth-system models and Earth observations as well as advanced data analytics and integration and interoperability with impact sector applications. They are DestinE system components, interfacing with the Digital Twin Engine, offering a seamless production service of actionable knowledge for users that results from the fusion of observational and simulated data of the physical Earth system and of impact-sector relevant information.

Digital Twin Engine (DTE): Software-defined environment to operate DestinE’s DTs and manage their corresponding control and data flows across distributed HPC and cloud computing resources. It provides a common system approach to a unified orchestration of Earth-system Digital Twins. Moreover, it creates a framework for the fusion of observations with Earth-system simulations and the integration of applications targeting specific impact-sectors via selected use cases. The DTE enables the porting and optimization of codes, developing and managing the digital twin workflows, and provides the data handling and model interaction and interactivity capabilities that run on diverse HPC and cloud infrastructures including the Data Warehouse hosted on the data bridges. The DTE concept focuses on interoperability and interactivity and delivers the expected access agility and performance for the digital twins and associated data access.

DestinE Entrusted Entity: an entity implementing respective entrusted tasks in connection with DestinE in accordance with their respective contribution agreements, such as ECMWF, ESA and EUMETSAT.

DestinE Entrusted Entity’s Contractor(s): a legal entity with which a DestinE Entrusted Entity has a contract for provision of services, supplies or works for the implementation of DestinE in accordance with a respective contribution agreement.

DestinE Services for Users Granted Upgraded Access: all services accessible to Users Granted Upgraded Access through DestinE Platform.
