Tiny particles floating in our air. This visualization shows how tiny particles called aerosols move through Earth's atmosphere from August 1 to September 14, 2024, using NASA's Goddard Earth Observing System (GEOS) model. These particles, which include sea salt, dust, smoke, and sulfates, can travel thousands of miles and affect air quality and visibility far from their original sources. By tracking these movements, NASA helps communities prepare for changes in air quality and visibility while advancing our understanding of Earth's complex atmospheric system.
