(particles suspended in an atmosphere)

Aerosols are particles floating around in the atmosphere, e.g., ice, water droplets, fine dust, or soot. In Earth's atmosphere, they are of interest to astronomers for their effect on seeing. On planets and moons (such as Titan) they are of interest as something to be explained, for their effect on the object's climate and weather, and for the challenge they present to viewing the object's surface.
