IMPRESSIVE Simulation of Aerosols Transport Courtesy of NASA

Even if we can't see them, aerosols play an important part in weather, pollution, and air quality. As NASA points out, they are recognized as one of the most important forcing agents in the climate system (Forster et al. 2007).  Using GEOS-5,  NASA's  Global Modeling and Assimilation Office have made available two very impressive simulations of aerosols distribution throughout the earth. It looks like gentle smoke moving about with the wind,  but it helps us see clearly how pollution can spread far and wide. We are more connected than we realize.
