Combined exploitation of VENμS, Sentinel-2 and Landsat-8: the spectral bands

=>

The combined use of VENμS, Sentinel-2 and Landsat-8 data can increase the likelihood of obtaining cloud-free images or may allow detailed tracking of rapidly evolving phenomena. In order to facilitate this combination, the table below summarizes the correspondences between the spectral bands of the instruments. VENμS does not have a spectral band in the middle infrared.

The figure below shows the spectral bands of VENμS and Sentinel-2 in the 400 to 1000 nm range. The SWIR bands of Sentinel-2 are not included.

The table below shows the usual band combinations

 

The figure below makes it possible to assess the degree of similarity of the spectral responses of these usual bands.

The detailed spectral responses of each instrument are available via the following web pages:

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. […]

BIOMASS, the third launched satellite mission designed at CESBIO !

After SMOS in 2009, and VENµS in 2017, the CESBIO laboratory is very proud to see its third proposed mission, Biomass, reach orbit. As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]
