The Upper Atmosphere: Meteorology and Physics focuses on the study of the characteristics, movements, composition, and observations of the upper atmosphere. The book first offers information on the meteorological conditions in the lower stratosphere and the structure and circulation of the upper stratosphere and the mesosphere. Topics include balloon sounding systems, climatology of the lower stratosphere, disturbed circulation of the lower stratosphere, rocket measurements, and frequent measurements with balloons and meteorological rockets. The text then ponders on the sun's radiation and the upper atmosphere and composition of the stratosphere and mesosphere. The manuscript elaborates on the composition and structure of the thermosphere, including photochemical processes, diffusion, composition and structure measurements, and structure of the thermosphere. The text also ponders on radiative processes and heat transfer; atmospheric tides and winds in the lower thermosphere; and transport of properties in the upper atmosphere. The publication is a valuable source of information for readers interested in the meteorology and physics of the upper atmosphere.
