CO3D Image Quality Calibration

Fabrice Buffe, Sylvain Lucas, Alice Latourte, Nicolas Delaygue et autres

Abstract. The launch of the four CO3D satellites took place on 25th July 2025. One of the goals of the mission is to generate a worldwide, accurate and low-cost Digital Surface Model (DSM) at a resolution and relative height accuracy of 1m. …

3D Product Quality Control in the CO3D Mission: A Critical Role

David Youssefi, Timothée Accadia, Emilie Colleu, Aymeric Godet et autres

Abstract. We present the qualification of 3D products as part of the CO3D mission. This mission aims at generating a global Digital Surface Model (DSM) of the Earth’s landmass. Massive automatic production is a challenge in itself as the ground segment delivers …

Sky-NeRF: Learning 4D Cloud Topography in a Dynamic Neural Radiance Field

Theïlo Terrisse, Dawa Derksen, David Youssefi, Hugo Méric

Abstract. We present Sky-NeRF, a novel method for cloud topography estimation based on Dynamic Neural Radiance Fields. Similar to NeRF, we propose to model the 3D structure of clouds as a radiance field, encoded in the parameters of a neural representation. Our …

Mass changes of the Antarctic Peninsula ice sheet and peripheral glaciers, 2007–2021

Maud Bernat, Etienne Berthier, Amaury Dehecq, Romain Hugonnet et autres

The Antarctic Peninsula (AP), encompassing the ice sheet and its peripheral glaciers, is a highly dynamic component of the cryosphere that disproportionately contributes to sea-level rise relative to its size. However, a large spread remains between the mass changes estimated using gravimetry, …
