Desert dust particles are lifted into the atmosphere by gusts of surface wind and can be transported and deposited thousands of kilometres away. 

When Saharan dust travels over populated areas, it can reduce air quality and impact health by causing respiratory problems and also cause flight delays. Over the oceans, dust can act as a fertiliser, stimulating blooms of tiny marine plants (phytoplankton) that are the basis for the marine food chain.

The image was captured by one of the two Copernicus Sentinel-3 satellites. 

The Sentinel-3 satellites are in a near-polar, sun-synchronous orbit at an altitude of 815 kilometres, and they are designed to monitor the Earth's oceans, land, ice, and atmosphere.

EUMETSAT operates the Copernicus Sentinel-3 satellites, in cooperation with ESA, and delivers the marine data on behalf of the European Union.
