Atmospheric aerosols have suspension of fluid, solid, or miscellaneous particles with highly unpredictable chemical composition and size distribution. Aerosols have various values of optical properties. Its unpredictability is due to the plentiful sources and unreliable structure mechanisms. The aerosol optical properties change regionally depending on emission and transport of aerosols, and meteorological conditions. Atmospheric aerosols have two properties like absorbing in nature and other than scattering nature on solar radiation which play very important role in modulating climate atmosphere and the hydrosphere. The aerosol when scatters the solar radiation then causes the warming in boundary layer. Aerosols particle properties change time to time through many processes like coagulation, condensation and chemical reaction. Ingestion of water by aerosol raises particles size and these processes depend on chemical composition, size of particles and ambient relative humidity.Read more..
