Collard et al. (2022) have shown that Sentinel-2 can be used to estimate the wave spectrum in the presence sea ice. The waves tilt the sea ice surface and therefore modulate the reflected radiation that is received by Sentinel-2 sensor. The wave spectrum extracted from the image can even be used to invert the wave […]
Colleagues from ESA are reportedly claiming that the cloud masks from the new version v2.10 of Sen2cor are « as good as those of MAJA, if not better ». Well, let’s check. MAJA is the Level2A processor we designed within CESBIO and CNES, to process time series of images such as those of Sentinel-2, LANDSAT, VENµS, TRISHNA, […]
=> As agreed by CNES, the Sentinel-HR phase-0 study report has been published on HAL. This report can therefore be widely shared and cited in your own work: Julien Michel, Olivier Hagolle, Anne Puissant, Pierre-Alexis Herrault, Thomas Corpetti, et al.. Sentinel-HR Phase 0 Report. [Research Report] CNES – Centre national d’études spatiales; CESBIO. 2022. ⟨hal-03643411⟩ […]
=> Avec l’accord du CNES, le rapport de l’étude de phase 0 Sentinel-HR vient d’être rendu public sur HAL. Ce rapport peut donc être diffusé largement, et cité dans vos travaux : Julien Michel, Olivier Hagolle, Anne Puissant, Pierre-Alexis Herrault, Thomas Corpetti, et al.. Sentinel-HR Phase 0 Report.

A bug affecting the AOT estimates and leading to underestimated surface reflectances in some rare cases concerns all MAJA v4.x versions prior to 4.5.4. Users activating the CAMS option shouldn’t have noticed, but if you don’t use CAMS auxiliary data you may face this issue. Therefore, we highly recommend all users to upgrade to the […]
Alors que les bassines se développent en France pour stocker l’eau en particulier en Pays de la Loire, elles sont aussi utilisées au Maroc dans un environnement bien plus aride. Dans la région désertique entre Errachidia et Boudnib, près de la frontière algérienne, l’apparition de ces piscines géantes a transformé le paysage. L’eau est prélevée […]

Viedma Glacier is an iconic glacier of the Southern Patagonia icefield. Landsat 5, Landsat 8 and Sentinel-2 images series show that its terminus has retreated by 3 km since 1985. Looking closer one can notice a new proglacial lake forming in a recently deglaciated area. Since I won 80 sq km of Airbus Pléiades data, […]
