High-resolution global atmospheric modelling, run on the Discover supercomputer at the Nasa Centre for Climate Simulation at Goddard Space Flight Centre, 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 kilometres.
This portrait of global aerosols was produced by a GEOS-5 simulation at a 10-kilometre resolution. Dust (red) is lifted from the surface, sea salt (blue) swirls inside cyclones, smoke (green) rises from fires, and sulphate particles (white) stream from volcanoes and fossil fuel emissions.
