Great news ! As announced in Sentinel-2 Mission status, laser links to geostationary relay satellites are now working, both for S2B (since last October) and S2B (since a few days ago). Sentinel-2 5 days repetitivity is now nominal above all lands, and that’s cool ! A big thank you to ESA, Copernicus and all the […]
=> MUSCATE is in a good shape these days thznkd to the continuous efforts of the development team (CNES and CAP GEMINI) who solved several issues. The counter of Sentinel-2 Level 2A products reached 70 000 products this night, just one month after reaching 60000. If we sum all the products delivered by MUSCATE, we […]
=>La recherche pour l’amélioration des performances des méthodes de MAJA repose actuellement sur une toute petite équipe au CESBIO, composée de deux personnes, Bastien Rouquié, qui travaille sur l’amélioration des estimations d’aérosols, et moi, qui passe presque tout mon temps en réunions, ou a écrire des articles de blog (et parfois les deux en même […]
=>Depuis la découverte des récents bugs et la mise en place de moyens de les contourner, le rythme de production de MUSCATE s’est accru, et nous avons donc pu étendre un peu les zones où nous fournissons des données Sentinel-2 (A&B) corrigées des effets atmosphériques, avec un bon masque de nuages: il s’agit de produits […]
=> Since we understood the bugs which were slowing MUSCATE, and we found ways to mitigate them, the production rhythm of MUSCATE improved and we were able to extend the zones where we provide Sentinel-2 (A&B) L2A products. L2A products provide surface reflectances after correction of atmospheric effects and with a high quality cloud mask. […]
New update: Muscate distribution server is back but you should use the following address until Monday: https://theia.cnes.fr/atdistrib/rocket/#/home . New products will be uploaded starting from Monday too. And since the week-end is there, it is not compulsary to downloard our L2A images until then (even if you can…)Update : the server will also be down […]
We are continuously working on improving the Sentinel-2 L2A products delivered by Theia. Since the 2nd of February, a new parametrization was put in production in order to improve two points of the cloud masks. There is a page which summarizes the variations of Theia product versions. Because of some error within Muscate production centre, […]
NDVI NDVI is by far the most commonly used vegetation index. NDVI was developed in the early seventies (Rouse 1973, Tucker 1979), and widely used with remote sensing in the nineties until now. It is computed from the surface reflectance in the red and near infra-red channels on each side of the red-edge. where and […]
En voyant ce titre dans la Dépêche, j’ai imaginé que les célèbres géoglyphes de Nazca avaient été complétement labourés. Peut-on utiliser Sentinel-2 pour constater l’ampleur des dégâts ? La dernière image du site a justement été acquise le lendemain du drame. Dans cette région aride du Pérou, les nuages sont rares, si bien qu’on peut […]
