A sunny Sunday just after an exceptional late-September snowfall… That’s already a stroke of luck. But the passage of Sentinel-2 on the same day makes this weekend even more special!

The snow cover map was immediately processed and distributed by the new Copernicus Snow & Ice monitoring service powered by Cesbio’s algorithms! You can explore it in your web browser here.

Ground validation was performed on Sunday in the beautiful Vallée du Marcadau by students from ENS geosciences master program who were visiting the region as part of their field trip with Pierre René (association Moraine).
