About book : Recent Atmosphere is the result of long term geological process, chemical and photochemical process of atmospheric elements and bio-geochemical process of the biosphere. In geography, these all atmospheric process are studied in the Climatology which is a branch of geography and climatology and its all process depends upon atmospheric elements, its physical, chemical, biological, photometric, thermal, electric, magnetic and electromagnetic properties and their process. These all properties of the atmospheric gases and particles not only determine the climatic process but also the composition and structure of the atmosphere. The “Atmosphere : An Introduction” not only deals composition, structure and atmospheric process but also try to elaborate all kith and keens of its gases type and their stratification in details. It tries to analyse the role of different layers of the gases and their importance to protect biosphere and its ecosystem. The book attempts to provide all information on recent basis, data and research works. That is why this book is more efficient and useful for all university students, research scholars and teachers. In this book both author have try to explain atmospheric facts with scientific view. When students try to find scientific data and facts in reference to explain atmospheric process and fact in this global warming age, they don’t find appropriate reference. This book provides solution with scientific view. The book 'Atmosphere : An Introduction' emphasis atmospheric composition structure and process in three unites 1. Unit first deals about composition of atmosphere in ree rence to their different gasses and their climatological effect on earth biosphere. 2. Unit second explain about the structure of defferent gaseous layaers and their function with their characteristics. 3. Unit third explore gaseous circulation and its climatic effect on earth's weather.
