This book discusses the characteristics of atmospheric aerosols and their effect on climatic conditions. Ground-based, air-borne and satellite data have been collected and analyzed. The measurement techniques and atmospheric conditions are provided in a detailed account. The book also includes extensive information on the organic and inorganic elements of atmospheric aerosol. The author explicates how aerosol particles are chemically and physically processed, temporally and spatially distributed, emitted, formed and transported. This book caters to the need of researchers to resolve several issues related to the complex interaction between atmospheric aerosols and climatology.
