Dust on snow in the Armenian Highlands

In English Sentinel-2 snow-ice

Simon Gascoin, 27 mars 2018

The ESA website featured this Sentinel-2 image of a large and thick plume of dust off Libya (click here to view in the Sentinel-Hub)

Contains modified Copernicus Sentinel data (2018), processed by ESA, CC BY-SA 3.0 IGO


This dust can be tracked up to 2000 km away from its source location towards the northeast, in the Armenian Highlands: the time series of Sentinel-2 images below show the region of Mount Artos (Artos Dağı, Արտոս) in eastern Turkey before, during and after the passage of the dust cloud

.

This « orange snow » was also observed in ski resorts in Russia and Romania but I could not find clear-sky satellite images there (only Instagram imagery 🙂 )

edit: on March 31st, a new Sentinel-2 image was acquired after a snowfall

A few days later this snow layer has already melted and the orange dust has resurfaced!

Dans le cadre du projet ACLIMO financé par le programme européen Interreg ALCOTRA, le Cesbio a été sollicité pour mettre en oeuvre un outil d’estimation de l’équivalent […]

The missing link to valorize CESBIO’s applicative research works

=>  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 […]
