When I say « a scary plot », I don’t mean a Chinese plot aimed at confusing some naive North Americans, it just mean a figure (an American one, by the way, made with data from the National Snow and Ice Data Center) that provides the total sea ice area over the globe. And this figure is […]

Hier avec mon collègue Pascal nous sommes allés réparer le pluviomètre de notre station météo dans le Vicdessos. Outre l’absence de neige anormale à cette saison, le versant d’en face était largement calciné ce qui donnait au paysage un aspect désolant.

The rift of Pine Island glacier was captured by Sentinel-2A several times since Sentinel-2A is watching Antarctica. However I was not sure if the crack was growing by looking at the images only.

=> Le graphique ci-dessus montre une série temporelle de réflectance TOA rassemblée par Sentinel-2 sur un pixel choisi au hasard dans une tuile au centre de la France (tuile 31TDK, pixel 3000-7000), à partir de produits L1C. En regardant la série chronologique, il est assez difficile de dire quel type de surface a été […]

=> The above plot shows the TOA reflectance time series gathered by Sentinel-2 over a pixel chosen randomly in a tile in the centre of France (tile 31TDK, pixel 3000-7000), from L1C products. Looking at the time series, it is rather difficult to tell what kind of surface was observed, even if a vegetation cycle […]
