NEMO working group on Machine Learning and Model Uncertainties

co-chairs : Andrea Storto and Julien Le Sommer

Scope

• Organize and plan the development of NEMO for modeling uncertainty (stochastic physics and ensembles)
• Organize and plan the development of NEMO in connection with machine learning
• Ensure liaison between projects focusing on NEMO-based ML applications and the NEMO DevCom and organize discussions on associated topics if relevant.
• Ensure liaison between projects focusing on using NEMO in connection with DA frameworks and the NEMO DevCom and organize discussion on associated topics if relevant.

Scientific discussion topics :

• Uncertainty quantification: learning representations of model errors and tuning model parameters.
• Differentiable emulation (of individual code components or entire models)
• ML-based subgrid parameterization
• Explicit representation of uncertainties (ensemble generation, stochastic modelling, multi-physics simulations)
