Satellites, balloon-borne instruments and ground-based devices make 30 million observations of the atmosphere each day. Yet these measurements still give an incomplete picture of the complex interactions within the membrane surrounding Earth. Enter climate models. Through mathematical experiments, modelers can move Earth forward or backward in time to create a dynamic portrait of the planet. Researchers from NASA Goddard's Global Modeling and Assimilation Office recently ran a simulation of the atmosphere that captured how winds whip aerosols around the world. Such simulations allow scientists to better understand how these tiny particulates travel in the atmosphere and influence weather and climate. In the visualization below, covering August 2006 to April 2007, watch as dust and sea salt swirl inside cyclones, carbon bursts from fires, sulfate streams from volcanoes—and see how these aerosols paint the modeled world.

A massive cloud of dust (red) blows from the Sahara over the Atlantic Ocean, where it may affect the formation or intensity of hurricanes.

Concentrations of sea salt (blue) sucked into Pacific Ocean typhoons and hurricanes appear as bright dots in the center of the storms.

Using models called GEOS-5 and GOCART, the simulation took several weeks to process on a NASA Center for Climate Simulation supercomputer.
