Satellites study deadly dust storms
10 May 2005
A dust storm moving across Africa's western Sahel belt on 3 March 2004, as seen by MSG-1, renamed Meteosat-8. The dust can be seen blowing offshore, even reaching the Canary Islands. Dust storms are being mapped as part of the ESA-led Epidemio project.
Desert dust blown from the Western Sahara towards the Canary Islands, seen in this 300-metre resolution Medium Resolution Imaging Spectrometer (MERIS) image, acquired 1 March 2003. The wind can move between 60 and 200 million tonnes of fine dust up from the Sahara each year.
