Book Description
Spacecraft study of the Solar system is one of humanity's most outstanding achievements. Thanks to this study, our present knowledge of properties of and conditions on the planets exceeds many-fold that of 20 years ago: planets have been rediscovered. This is especially the case for planetary atmospheres, whose properties were for the most part either not at all or only erroneously known. Much research has been invested in the study of the atmospheres of Mars and Venus, and their chemical composition and photochemistry are basic problems in these studies. In the present publication I have tried to summarize all findings in this field. The English version of the book includes new data in the field from the last 3 years since the book was published in Russian. I wish to thank U. von Zahn, who initiated my talks with Springer-Verlag and acted as technical editor. December 2, 1985 V. A.

Book Description
This valuable reference presents detailed studies of eleven planetary atmospheres: four for the giant planets (Jupiter, Saturn, Uranus, and Neptune), four for the small bodies (Io, Titan, Triton, and Pluto), and three for the terrestrial planets (Mars, Venus, and Earth). Also, using the database provided by recent space missions supplemented by Earth-based observations, the authors offer an extensive survey of the principal chemical cycles that control the present composition and past history of planetary atmospheres.

Book Description
The chemical composition of any planetary atmosphere is of fundamental importance in determining its photochemistry and dynamics in addition to its thermal balance, climate, origin and evolution. Divided into two parts, this book begins with a set of introductory chapters, starting with a concise review of the Solar System and fundamental atmospheric physics. Chapters then describe the basic principles and methods of spectroscopy, the main tool for studying the chemical composition of planetary atmospheres, and of photochemical modeling and its use in the theoretical interpretation of observational data on chemical composition. The second part of the book provides a detailed review of the carbon dioxide atmospheres and ionospheres of Mars and Venus, and the nitrogen-methane atmospheres of Titan, Triton and Pluto. Written by an expert author, this comprehensive text will make a valuable reference for graduate students, researchers and professional scientists specializing in planetary atmospheres.

Book Description
The Photochemistry of Atmospheres: Earth, the Other Planets, and Comets discusses the photochemical and chemical processes in atmospheres This book focuses on the earth’s atmosphere in the past, present, and future, atmospheres of other planets and their satellites, and comets. General topics in atmospheric photochemistry, such as composition and structure, transfer of incoming solar radiation, and principles governing the rates of photochemical and chemical processes are also elaborated. This text also covers the role of eddy and molecular transport and continuity-transport equation used in theoretical numerical modeling studies. This publication is recommended for advanced-level courses in the atmospheric and planetary sciences, as well as reference for those interested in learning about atmospheric/climatic environmental problems, their causes and consequences, and discoveries concerning the atmospheres of neighboring worlds.

Book Description
Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s. These orbiters, landers and rovers have generated vast amounts of data that now span a Martian decade (roughly eighteen years). This new volume brings together the many new ideas about the atmosphere and climate system that have emerged, including the complex interplay of the volatile and dust cycles, the atmosphere-surface interactions that connect them over time, and the diversity of the planet's environment and its complex history. Including tutorials and explanations of complicated ideas, students, researchers and non-specialists alike are able to use this resource to gain a thorough and up-to-date understanding of this most Earth-like of planetary neighbours.

Book Description
The inherent errors of applying terrestrial atmospheric ozone distribution studies to the atmosphere of other planets are discussed. Limitations associated with some of the earlier treatments of photochemical equilibrium distributions of ozone in planetary atmospheres are described. A technique having more universal application is presented. Ozone concentration profiles for the Martian atmosphere based on the results of the Mariner 4 radio occultation experiment and the more recent results with Mariner 6 and Mariner 7 have been calculated using this approach.
