The Atmosphere of Aqua-planet Earth : Its Vertical Structure and Interactions with Space

A planetary atmosphere is the gaseous layer that divides the planetary surface and surrounding space.Although the Earth's atmosphere occupies a tiny fraction of the total Earth's mass, it plays an essential role to make the Earth's surface environment circulating liquid-water that is thought to be the most fundamental condition for the emergence and evolution of the terrestrial life organisms.The vertical structure of Earth's atmosphere from the Earth's surface to the uppermost region that merges into space is strongly influenced by interactions with space.
