This map represents the global distribution of sulfur dioxide and dust particles from the Mount Pinatubo eruption. A computer model tracked particles from the blast and found that it took less than three months to spread throughout Earth's atmosphere. The colors in the graphic represent the atmospheric height of the particles. The blue dots are particles closer to Earth's surface, while the red dots represent the highest particles in the atmosphere.
