Is it possible to see the atmosphere? Scientists are able to do so by tracking what is carried on the wind. In this simulation, tiny aerosol particles such as smoke, dust, and sea salt are transported across the globe, making visible weather patterns and other normally invisible physical processes. This visualization uses data from NASA satellites, combined with mathematical models in a computer simulation. It allows scientists to study the physical processes in our atmosphere. For example, by following the sea salt that is evaporated from the ocean, you can see the storms of the 2017 hurricane season. You also can see smoke from the large fires in the Pacific Northwest released into the atmosphere. This simulation shows how large weather patterns can transport these particles long distances: in early September, you can see a line of smoke from Oregon and Washington, down the Great Plains, through the South, and across the Atlantic to England. Dust from the Sahara is also caught in storm sytems and moved from Africa to the Americas.
