First, CLAIMA will adapt and validate state-of-the-art AI climate models against observations and high-fidelity simulations, creating engines that are both fast and reliable. Second, it will engineer a modular and interoperable digital twin platform to support training, inference, evaluation and user access across Europe’s research infrastructures. Third, it will demonstrate value in real-world applications, including climate science, through use cases co-designed with stakeholders. The system will combine a robust web-based interface with a natural-language assistant, with clear communication of AI use, limits and impacts. CLAIMA directly addresses HORIZON-INFRA-2025-01-TECH-04 by applying GenAI4EU-aligned methods to set up and manage complex modelling across research infrastructures. It will establish best practices for AI model generation and data fusion, demonstrate interoperability with DestinE, and enable innovative applications in key impact sectors. By providing a durable European infrastructure for climate AI, CLAIMA will accelerate scientific discovery, support climate adaptation, and strengthen Europe’s global leadership in trustworthy digital twins.
