Very small liquid or solid particles dispersed in air. The ocean waves which produce sea salts, wind that blows mineral dust, and biogenic emission are all some of the most common natural sources of aerosol. Aerosol makes up a vital factor in the climate of the earth through transmitting sunlight into space, with darker aerosols being more capable in absorbing larger amounts of light. The atmosphere is increasingly cooled as nitrates and sulfates reflect all exposing radiation.
