We had announced quite a long time ago the coming availability of MAJA 3.1 to correct for the atmospheric effects on Sentinel-2, Landsat 8 or Venµs satellites. This version brings a significant improvement in the estimation of Aerosol Optical Thickness, thanks to the use of Copernicus Atmosphere Monitoring Service (CAMS) data to constrain the aerosol […]
More exactly: two maps of 934’343’100 pixels! We [1] have processed 6205 Sentinel-2 images and 593 Landsat-8 images to compute the annual snow cover duration in the Alps and the Pyrenees at 20 m resolution for hydrological years 2016-2017 and 2017-2018. The snow cover duration (or snow persistence) is defined as the total number of […]
Le centre de calcul (de haute performance) du CNES sera en maintenance les 4 et 5 décembre, dans le but d’accroitre sa robustesse et ses performances. En conséquence, MUSCATE ne sera pas en mesure de produire les données de Sentinel-2, Landsat et Venµs en temps réel. Pour une fois, nous ne serons donc pas en […]
=> The Level 2A data production with MAJA processor, by MUSCATE processing center is now fast and efficient. Some margins have been found to add new zones to our production. (The zones already processed are displayed here). French public institutes of labs that would need new zones can tell us their needs, we should still […]
=>La production des données Sentinel-2 au niveau 2A, avec la chaîne MAJA, par le centre MUSCATE de Theia est maintenant rapide et efficace, nous disposons donc de quelques marges pour ajouter de nouvelles zones (les zones actuelles sont visibles ici). Les organismes français intéressés par l’ajout de nouvelles zones peuvent d’ailleurs me contacter, il devrait […]
This is a time-lapse of all clear-sky images captured by Venµs over the Khumbu Icefall near Mount Everest since November 2017 (one year of data, 51 images at 5 m resolution) . Here I used the Level-1C products (i.e. without atmospheric correction) because the Level-2A products are provided at a lower resolution (10 m). Anyway, […]
If you are not afraid to spend too much time while you have urgent things to do, you may have a look to the mosaic of Sentinel-2 monthly syntheses for September over France. You may access to each monthly synthesis using the following links : Or you may also use the viewer below to compare […]
=> Every four years, CNES brings together its scientific advising committees (and I have never been invited 🙁 ) for its scientific prospective seminar. This seminar is where the scientific priorities for CNES’s next space missions are defined. A few months before, a call for ideas for new missions is issued, and it was the […]
=>Tous les 4 ans, le CNES réunit la fine fleur de ses comités scientifiques ( d’ailleurs, je n’ai jamais été invité 🙁 ), pour son séminaire de prospective. C’est à cette occasion que sont définies les priorités scientifiques pour les prochaines missions spatiales du CNES. Quelques mois avant, un appel à idées pour de nouvelles […]
