Copahue is an active volcano in the Andes on the Chile-Argentina border. It erupted in 2016 and a plume of smoke was visible in many Sentinel-2 images during that period. Looking at these pictures I thought it would be fun to use that plume as a giant anemometer to evaluate climate model data. I extracted […]
Snow and ice products are now available at high resolution (20×20 m) for all Europe in near-real time. However, Magellium is also processing the Sentinel-2 archive since September 2016. About 70% of Sentinel-2 observations have already been processed and 50 % are already published. This huge computation is being done on the CNES HPC […]
« Give me a hundred tries, I’ll never be able to spell it. » Jimmy McGill I haven’t seen the « Breaking Bad » series but I’m a huge fan of « Better Call Saul ». Both series take place in Albuquerque, New Mexico. With its dry, sunny weather, Albuquerque is the perfect place for a modern-day Western. Vince Gilligan, the […]
We have been waiting for a long long time, but it seems the production of geometry refined Sentinel-2 L1C will start by next month. I have heard ESA plans to reproduce the whole data set later on, but the schedule has not been announced yet. « Start of the geometry-refined production using the Global Reference Image […]
=> In 2018, Olivier Hagolle presented in this article the Sentinel-HR concept : an optical satellite in the metric spatial resolution class providing global, repetitive, systematic observations with an open access policy. By doing so, he continued the work of Gérard Dedieu who had already advocated for this concept in the previous years. Thanks to […]
=> MAJA est un logiciel de détection de nuage et de correction atmosphérique de qualité, développé par le CNES et le CESBIO, avec des contributions du DLR. Il est codé par CS GROUP. MAJA est utilisé pour traiter les données Sentinel-2 par le Pôle Theia, par les projets Sen2Agriet Sen4cap de l’agence spatiale Européenne, par […]
=> MAJA is the high quality cloud detection and atmospheric correction code developped by CNES and CESBIO, with contributions from DLR, and coded by CS GROUP. It is used within Pôle Theia, Sen2Agri, Sen4cap, DLR, EEA Snow&Ice, KERMAP… to process #Sentinel2 time series. It’s been a long time since we wanted to make MAJA available […]
=> A few days ago, the Theia land data centre released the July 2020 monthly cloud free synthese of surface reflectances from Sentinel-2, for France, but also Italy, Spain, Switzerland, Belgium, Netherlands, the Northern part of Maghreb and Madagascar, and a large part of Sahel The distribution site of Theia products at CNES now provides […]
Update (18/08/2020): all the issues have been corrected, MUSCATE production and distribution have resumed. Update (17/08/2020): production has resumed, but it will take us a couple of days to catch the backlog up. The download site is still offline, but this should be solved quickly. Following the failure of an equipement which hosts the […]
