Publication of the Sentinel-HR phase-0 study final report

=> 

As agreed by CNES, the Sentinel-HR phase-0 study report has been published on HAL. This report can therefore be widely shared and cited in your own work:

Julien Michel, Olivier Hagolle, Anne Puissant, Pierre-Alexis Herrault, Thomas Corpetti, et al.. Sentinel-HR Phase 0 Report. [Research Report] CNES – Centre national d’études spatiales; CESBIO. 2022. ⟨hal-03643411⟩

This report summarizes 15 months of work from a small team at CNES, helped by an enthusiast scientific mission group, and with a greatly appreciated support and small funding from the prospective team at CNES. It is organised as follows:

  • Chapter 1 describes the programmatic context of the mission as well as objectives and means of the phase-0 study
  • Chapter 2 describes Sentinel-HR expected benefits through 12 application use-cases
  • Chapter 3 describes two possible designs for the mission : one uses a pair of ad-hoc satellites, the other use 12 modified CO3D satellites
  • Chapter 4 presents our work on spatio-temporal fusion and super-resolution in order to assess the feasiblity of Sentinel-HR / Sentinel-2 (NG) hybrid products

Many thanks to all (often benevolent) contributors !

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 […]

Dates de fauche en France

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 […]

Évolution du jour de déneigement dans les Alpes françaises et les Pyrénées

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. […]
