Modeling the World in High Resolution

NASA scientists call it "Paint by Particle," a whimsical name that downplays the complex amount of calculations needed to paint this picture.
Those colourful streams you see in the video above, provided by NASA Goddard`s Global Modelling and Assimilation Office, are different types of particles, blown around by the earth`s winds.
These particles move around Earth`s atmosphere, scientists can puzzle out how they affect weather and climate over time.
With these models, the stream of dust (red) from Africa over the Atlantic may affect the formation or intensity of hurricanes.
Sea salt (blue) sucked into Pacific Ocean typhoons may appear as bright dots in the centre of the storms.
Fires across Africa and South America spew black and organic carbon (green) into the atmosphere.
And the white particles, representing sulphates, can be used to track the progress of volcanic eruptions, among other things.
NASA says climate models such as these are based on more than 30 million daily observations of the atmosphere by satellites, weather balloons and ground-based detection sites.
