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, […]
=> Following its installation in March 2021, our new ROSAS device at Lamasquère has produced a first series of acquisitions over a complete maize crop cycle. The ROSAS system is based on the use of a multi-spectral photometer to carry out angular and spectral measurements of both incident and reflected radiation from the surface. The […]
Last year in November we noticed these unusual white spots in a Sentinel-2 image near Barèges… These white spots were artificial snow spread by snow cannons. At the same time of the Sentinel-2 acquisition, they were also « visible » as cold spots from our thermal infrared camera installed at Pic du Midi. This year in November […]
Sentinel-2 captured an impressive view of the Fraser river sediment plume in Georgia Strait caused by the historic flood in British Columbia (250 mm rainfall in 48 hours). The image contains an amusing detail west off the Vancouver International Airport. This red-green-blue object is an airplane or « plainbow« . It is due to shifts between the […]
En janvier dernier nous vous annoncions la mise en couveuse d’un bel iceberg au terminus du glacier de l’Astrolabe … Yann Niort qui travaille actuellement pour Météo-France en Terre-Adélie nous a signalé que le glacier avait enfin vêlé ! En fait ce n’est pas un iceberg mais une jolie portée de plusieurs icebergs que l’Astrolabe […]
There are several MAGicians in the CESBIO laboratory, and I am one of them (with all due modesty). According to my definition, MAGicians are participants to Mission Advisory Groups, for instance for CNES or ESA satellite projects. These days, I participate to the MAG for Sentinel-HR at CNES, and for Sentinel-2 Next Generation at ESA. […]
