Aerosols are suspensions of solid or liquid particles in air. The particles are sufficiently small that their settling due to gravity is minimal, leading to long residence times in the atmosphere. Their atmospheric significance is multifold. For example, they play an important role in polluted urban environments by lowering visibility and leading to health problems in humans. They also catalyze reactions that affect atmospheric chemical composition, leading, for example, to the Antarctic ozone hole.
