TRACCS (TRAnsformative Advances in Climate modelling for Climate Services) is a new French programme which will start in 2023 and run for the next eight years. TRACCS will combine several types of activities:
i) process modelling for simulating climate from global to local scales, so as to provide reliable climate information for assessing both mitigation scenarios and local adaptation actions and their feedback effects on the climate,
ii) adaptation of computer codes to new computing architectures, to seize the opportunities offered by exascale in terms of increasing spatial resolution, better representing the complexity of the climate system, and exploring large sets of simulations and obtain better information on model and scenario-related uncertainties,
iii) the use of advanced statistical methods and artificial intelligence to characterise climate extremes, accelerate models, and develop emulators (fast statistical models) to better quantify uncertainties,
iv) the estimation of the impacts of climate change on different activity sectors and different territories in order to co-construct adaptation,
and v) the development of a dialogue between scientists and stakeholders, teaching and communication with all audiences in order to co-construct prototypes of climate services in a transdisciplinary approach.
These activities, together with the training of a new generation of experts in climate change and its impacts, have the ambition to transform the way scientific advances on climate change are shared with stakeholders, thereby multiplying the capacity for science-based adaptation and mitigation.

The programme is jointly managed by CNRS and Meteo-France and involves key partners (CEA, IRD, CERFACS, Université-Grenoble-Alpes, Sorbonne Université, Université Versailles-Saint-Quentin, Université Paris-Saclay) in modelling and understanding climate change and its potential impacts.

Our poster presentation will give us an opportunity to present this new project and build collaborations with similar projects at the European and international level.
