Copernicus provides near real time snow cover maps at 20 m resolution (fractional snow cover, code name: FSC OG). These products have been recently reprocessed and are now available through the Copernicus Data Space Ecosystem (CDSE) API and visualization tool, the Copernicus Browser! The latter is very useful to explore the data, for example if […]
=> My colleagues at CESBIO are extremely creative! Over the past ten years, they have developed a wide range of new products and methods for extracting information from Copernicus data. They don’t just develop and validate the method on a few sites; they continue their work until they have produced data for the whole of […]
=> Mes collègues du CESBIO sont très créatifs ! Ils ont mis au point, au cours des dix dernières années, un grand nombre de nouveaux produits et de méthodes d’extraction de l’information à partir des données Copernicus (Sentinel-1 et 2). Et bien souvent, ils ne s’arrêtent pas à la mise au point de la méthode […]
OpenAlex is a new, yet already very useful, open database for exploring scientific literature. For an upcoming blog post on the CNES Datacampus website, I analysed the proportion of papers that used only one of the Sentinel-2 or Landsat missions, as well as those that used both, in 2025. What struck me was that Sentinel-2 […]
This blog post is not a review of the excellent and deeply philosophical, parallel-universes delirium movie by Daniel Kwan and Daniel Scheinert, but the title of this drama resonates with the capabilities of our latest algorithm, which has just been published in Remote Sensing of Environment: J. Michel and J. Inglada, « Temporal attention multi-resolution fusion […]
Due to the success of Olivier’s petition, ESA kept Sentinel-2A operational after the launch of Sentinel-2C. Having three operational satellites instead of two increases the revisit, which should improve the quality of the derived products, and therefore the reliability of operational services based on Sentinel-2 data. One of this service is the Copernicus’ High Resolution […]
Pakistan news media reported that a glacier lake outburst flood (the failure of a dam containing a glacial lake) occurred near Gupis, Gilgit-Baltistan, a highly mountainous region administered by Pakistan. Satellite images show that the flood triggered a debris flow, which reached the Gupis valley where it hit the Roshan (Rashon) village and blocked the […]
En 2024, des collègues du Cesbio ont publié un article* sur la cartographie de la date de fauche en France en 2022 à partir des données satellitaires Sentinel-2. Leur magnifique figure 10 a attiré mon attention. La version à haute résolution fournie avec l’article (2861 × 2911 pixels) correspond à une image dont les pixels font […]
Les socio-écosystèmes des Alpes et des Pyrénées dépendent étroitement des fluctuations annuelles du manteau neigeux. En particulier, le moment de l’année où la neige disparait détermine le début de la saison de croissance de la végétation de montagne et donc la période des estives. Le changement climatique est en train de bouleverser ce rythme saisonnier. […]
