Landsat 8 is the United States Geological Survey’s most recently launched satellite, and it holds the powerful Operational Land Imager (OLI.) The OLI is a powerful multi-spectral imager with a wide dynamic range.
The OLI does a great job of keeping an eye on Earth, and now its captured images of winds in Namibia picking dust up and carrying it out over the Atlantic Ocean.
Dust plumes are a natural phenomena, part of Earth’s nutrient cycle. They occur when high-velocity winds pick up tiny dry particles from the Earth’s surface and carry them long distances. Every summer, dust plumes from Africa’s Sahara desert travel across the Atlantic Ocean.
They’re usually not this big, and they often sink into the ocean. But this one’s coming right to America.
