This image, released by Nasa, was created by a supercomputer designed to model aerosols in the Earth's atmosphere.
It shows how dust, sea salt, smoke and sulphates travel - and could dramatically improve weather forecasts.
The high-resolution global atmospheric modeling was done using the Discover supercomputer at the NASA Center for Climate Simulation at Goddard Space Flight Center in Maryland.
Nasa said the facility 'provides a unique tool to study the role of weather in Earth's climate system.'
The Goddard Earth Observing System Model, Version 5 (GEOS-5) is capable of simulating worldwide weather at resolutions of 10 to 3.5 kilometers (km).
This portrait of global aerosols was produced by a GEOS-5 simulation at a 10-kilometer resolution. 
Dust (red) is lifted from the surface, sea salt (blue) swirls inside cyclones, smoke (green) rises from fires, and sulfate particles (white) stream from volcanoes and fossil fuel emissions.Dust, in red, swirls over Europe, while close to the Australian coast, sea salt (blue) is clearly visible

The supercomputer has previously been used to recreate major weather events, such as this image of the humidity on June 17, 1993, during the Great Flood that hit the Midwestern United States
