A massive dust storm swept across northern Africa in mid-March 2020, blanketing the skies from Senegal to Eritrea. Dust from the Sahara Desert also blew westward over the North Atlantic Ocean a well as eastward over the Arabian Peninsula—a distance of more than 4,000 miles—over two days.
On March 14, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired this true-color image capturing the dust-filled skies over the Central African Republic (west), South Sudan, and Sudan (north). The dust is so thick in some areas, especially in the southern section of the image, that it obscures the view of the landscape. Africa’s Sahara Desert is one of the world’s major sources of dust, and dust storms are the primary natural hazard in most of the countries in this region.
Thanks to NASA’s Worldview app the progress of the dust storm can be viewed as it crosses Africa on March 13 and March 14. A roll-over image illustrating the progress can be seen HERE
