Summary

Description
English: Dust storms are common in the Sahara in early winter. This image, acquired by one of the Copernicus Sentinel-3 satellites on 1 December, shows a plume rising over the Bodele depression, the site of a vast ancient lakebed in Chad. The plume seen on 1 December is so long that it reaches modern Lake Chad, more than 250 km away. Data acquired by the Copernicus Sentinel-3 satellites allow accurate imaging of atmospheric particulate matter, including emissions from wildfires or desert dust. These data enable scientists to improve modelling of both climate change and air quality.
