Training neural mapping schemes for satellite altimetry with simulation data

no code implementations19 Sep 2023 Quentin Febvre, Julien Le Sommer, Clément Ubelmann, Ronan Fablet

Here, we leverage both simulations of ocean dynamics and satellite altimeters to train simulation-based neural mapping schemes for the sea surface height and demonstrate their performance for real altimetry datasets.

Benchmarking

Scale-aware neural calibration for wide swath altimetry observations

no code implementations9 Feb 2023 Quentin Febvre, Clément Ubelmann, Julien Le Sommer, Ronan Fablet

Sea surface height (SSH) is a key geophysical parameter for monitoring and studying meso-scale surface ocean dynamics.

A DNN Framework for Learning Lagrangian Drift With Uncertainty

1 code implementation12 Apr 2022 Joseph Jenkins, Adeline Paiement, Yann Ourmières, Julien Le Sommer, Jacques Verron, Clément Ubelmann, Hervé Glotin

Reconstructions of Lagrangian drift, for example for objects lost at sea, are often uncertain due to unresolved physical phenomena within the data.

Position

Joint calibration and mapping of satellite altimetry data using trainable variational models

no code implementations7 Oct 2021 Quentin Febvre, Ronan Fablet, Julien Le Sommer, Clément Ubelmann

The proposed framework significantly outperforms the operational state-of-the-art mapping pipeline and truly benefits from wide-swath data to resolve finer scales on the global map as well as in the SWOT sensor geometry.
