The phenomenon is only observed at this time of year. It is caused by strong winds carrying glacial flour – a fine silt generated by the glacial erosion of rocks. The Sentinel-2 image shows a dust cloud that has travelled more than 85 km down a fjord north of Sisimiut, before reaching Davis Strait.
This image, acquired by one of the Copernicus Sentinel-2 satellites on 18 October 2021, shows a dust storm in western Greenland.
Data acquired by the Copernicus Sentinel satellites are used to detect changes on the Earth's surface in great detail at northern latitudes and to help monitor the melting of glaciers.
