The 'Traccs' (climate) exploratory PEPR
Transforming climate modeling for climate services
Climate change poses urgent and complex challenges for all human societies, requiring increasingly accurate modelling tools and climate services tailored to the needs of different regions and sectors. To address these challenges, the TRACCS research programme is working to improve our understanding
of climate processes, develop more reliable models and co-construct solutions with all stakeholders. The objective is to provide robust, accessible and actionable climate information to guide mitigation and adaptation policies in France and internationally.

The TRACCS programme draws on a wide range of disciplines, including climate science, artificial intelligence, high-performance computing, and the humanities and social sciences. It aims to improve the accuracy of models by incorporating fine-scale extreme phenomena, essential components such as polar ice caps, and interactions between the water, carbon and atmospheric cycles. The challenge is also technological, with the adaptation of models to new computing architectures and the exploitation of opportunities offered by AI.
The applications are numerous: agriculture, health, resource management, land use planning, and even the adaptation of cities to heat waves. By combining expertise and involving stakeholders from the design stage onwards, TRACCS promotes the emergence of operational climate services that meet the needs of regions and socio-economic sectors.
Finally, the programme contributes to the sustainable structuring of the French climate science community by training a new generation of specialists and strengthening interdisciplinary cooperation, which is essential for better preparation for climate change and its consequences.
