3 days, 9 models, 1 goal: benchmarking mortality in #EarthSystemModels 🌍

From data & model overviews to hands-on coding sessions, we worked toward a shared framework, common metrics, and first results for a joint paper.

Great collaboration across teams & time zones! 🚀

💡 New Paper!
#MachineLearning improves #EarthSystemModels, but explaining its added value is tough. Inspired by climate model hierarchies, we propose using Pareto-optimal models to distill ML's added value in representing cloud cover, radiative transfer and tropical precipitation.

#AI4PEX research focus 6: Uncertainty Quantification

To overcome limitations of traditional manual calibration methods, such as high computational costs and slow iterative processes, we improve uncertainty quantification by leveraging on Perturbed Parameter Ensemble.

#AI4PEX research focus 2: Model Development

To develop better #EarthSystemModels we will expand the use of #EarthObservation in combination with #MachineLearning. We focus on explainability of #AI models and causality to better identify model-observations mismatch.
December 28, 2024 at 2:00 PM
#AI4PEX research focus 1: #EarthObservation

We leverage existing in-situ observations and EO data-streams to generate new upscaled #MachineLearning -based products, and cross-check with the Copernicus land, ocean and atmospheric datasets.
