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!

Sentinel-2 reveals the surface deformation after the 2025 Myanmar earthquake

Sentinel-2 captured several clear-sky images of Myanmar before and after the 28 March 2025 earthquake. The animation below shows a 5-day apart sequence of images captured by Sentinel-2B and Sentinel-2C (10 m resolution) near the epicenter located close to Mandalay. The surface slip due to the earthquake follows the Sagaing Fault, a major fault in […]

Evolution de l’altitude de la ligne de neige au cours des 41 dernières années dans le bassin versant du Vénéon (Oisans)

Pour contribuer à caractériser les conditions hydrométéorologiques lors de la crue torrentielle qui a frappé la Bérarde en juin, j’ai analysé une nouvelle série de cartes d’enneigement qui couvre la période 1984-2024 [1]. Grâce à la profondeur temporelle de cette série, on constate que l’altitude de la ligne de neige dans le bassin versant du […]
