TORONTO – A NASA satellite has captured dust from the Sahara desert as it moves across the Atlantic Ocean.

The Suomi NPP satellite’s VIIRS instrument made three passes above the eastern Atlantic on July 31, imaging the plume that extends almost 3,100 km into the Atlantic.

NASA also released a model which illustrates how the plume is expected to travel across the Atlantic Basin over the next week. There is some debate as to whether the Saharan Air Layer contributes or diminishes the development of hurricanes.
