The study of the Earth's atmosphere, its processes and the effects of other systems on its atmosphere and vice versa is known as atmospheric science. This field has three significant domains- meteorology, aeronomy and climatology. Atmospheric science uses lasers, radiosondes, rocketsondes, satellites and weather balloons for different studies. The discipline of atmospheric science can be divided into three categories- atmospheric chemistry, atmospheric dynamics and atmospheric physics. Atmospheric chemistry studies the chemistry of the Earth's atmosphere. Some of the issues dealt in this domain include acid rain, global warming and photochemical smog. Atmospheric dynamics studies diverse phenomena such as tornadoes, tropical cyclones, jet streams, thunderstorms, etc. Atmospheric physics strives to model the atmosphere using wave propagation models, statistical mechanics, cloud physics, etc. This book provides significant information of this discipline to help develop a good understanding of atmospheric science and related fields. It aims to shed light on some of the unexplored aspects and the recent researches in this field. Scientists and students actively engaged in this field will find atmospheric science full of crucial and unexplored concepts.
