This Medium Resolution Imaging Spectrometer (MERIS) image is centred over the Namib Desert located in Namibia. The desert stretches about 1,930 kilometres along the coast of southwest Africa, mostly within the Namibian country. Visible are the huge sand dunes that rise near the coast of the Atlantic Ocean and extend inland for up to 160 kilometres, ending at the steep slopes of the Great Escarpment (lower centre right).
