Synopsis Atmospheric Structure and Its Variations in the Lower Thermosphere by : K. S. W. Champion
This is a report prepared for the intermediate altitude region (the lower thermosphere, lying between about 100 and 200 km). This region dif fers considerably from the lowest one, in which the volume of data makes statistical methods of analysis appropriate. For the highest region, a considerable amount of satellite data is available and the behavior of the atmosphere is reasonably well understood. Some rocket data is available for the lower thermosphere, but most of the meas uring instruments are experimental and a major part of the data analysis consists in studying the physics of the various corrections or calibra tion factors required. At the upper end of the altitude regime some satellite data is available. New density data includes the results from flights of two types of falling spheres, results from the diffusion of chemical clouds, and data from drag effects on three satellites with perigee altitudes near 200 km. The satellite data indicates a de pendence of density on the value of the magnetic A sub p index. Otherwise, the data shows more variation with the method of measurement and data reduction than actual variation of the atmosphere. (Author).

Synopsis Atmospheric Structure in the Lower Thermosphere by : K. S. W. Champion
This review constitutes a revision and up-dating of the report, Atmospheric Structure and its Variations in the Lower Thermosphere (AD-417 201). It has been prepared for inclusion as an appendix in the proposed new edition of the COSPAR International Reference Atmosphere (CIRA). New density data presented and discussed include the results of four falling-sphere density measurements made at White Sands, New Mexico, and densities deduced from drag effects on Explorer XVII and other satellites. The satellite density data is compared with the predictions of several models of Jacchia and Harris and Priester. Temperature data include revised values deduced by Blamont from Doppler broadening of sodium and potassium resonance lines. The new values are in better agreement with theoretical models than the earlier results. Recent composition results include number densities of O2, N2 and O calculated from ultraviolet absorption measurements by Hinteregger, and values of mean molecular mass from Explorer XVII and the rocket measurements of Nier and Schaefer.

Synopsis The Atmosphere and Climate of Mars by : Robert M. Haberle
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.

Synopsis Middle Atmosphere by : PLUMB
PAGEOPH, stratosphere, these differences provide us with new evidence, interpretation of which can materially help to advance our understanding of stratospheric dynamics in general. It is now weil established that smaller-scale motions-in particular gravity waves and turbulence-are of fundamental importance in the general circulation of the mesosphere; they seem to be similarly, if less spectacularly, significant in the troposphere, and probably also in the stratosphere. Our understanding of these motions, their effects on the mean circulation and their mutual interactions is progressing rapidly, as is weil illustrated by the papers in this issue; there are reports of observational studies, especially with new instruments such as the Japanese MV radar, reviews of the state of theory, a laboratory study and an analysis of gravity waves and their effects in the high resolution "SKYHI" general circulation model. There are good reasons to suspect that gravity waves may be of crucial significance in making the stratospheric circulation the way it is (modeling experience being one suggestive piece of evidence for this). Direct observational proof has thus far been prevented by the difficulty of making observations of such scales of motion in this region; in one study reported here, falling sphere observations are used to obtain information on the structure and intensity of waves in the upper stratosphere.

Synopsis Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System by : Yukitoshi Nishimura
Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System provides a systematic understanding of Magnetosphere-Ionosphere-Thermosphere dynamics. Cross-scale coupling has become increasingly important in the Space Physics community. Although large-scale processes can specify the averaged state of the system reasonably well, they cannot accurately describe localized and rapidly varying structures in space in actual events. Such localized and variable structures can be as intense as the large-scale features. This book covers observations on quantifying coupling and energetics and simulation on evaluating impacts of cross-scale processes. It includes an in-depth review and summary of the current status of multi-scale coupling processes, fundamental physics, and concise illustrations and plots that are usable in tutorial presentations and classrooms. Organized by physical quantities in the system, Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System reviews recent advances in cross-scale coupling and energy transfer processes, making it an important resource for space physicists and researchers working on the magnetosphere, ionosphere, and thermosphere. - Describes frontier science and major science around M-I-T coupling, allowing for foundational understanding of this emerging field in space physics - Reviews recent and key findings in the cutting-edge of the science - Discusses open questions and pathways for understanding how the field is evolving

Synopsis Atmospheric Structure and Its Variations in the Region from 25 to 120 Km by : Gerald V. Groves
This report has been prepared as part of the activities of the Committee on Space Research (COSPAR) panel on a new reference atmosphere, which will aid in the design of aircraft, missiles and satellites. It combines a review of observational results obtained over approximately the last six years on temperature, pressure, density and winds with new models for the seasonal and latitudinal dependence of these parameters at heights from 25 km to the lower thermosphere. The temperature, pressure and density models extend from 25 to 110 km and are identical with those previously given in Report AFCRL-70-0261, May 1970 (Air Force Surveys in Geophysics, No. 218). W-E wind models are presented separately for the regions 25 to 60 km and 60 to (approximately) 120 km. Three W-E wind models from 25 to 60 km are presented corresponding to N. American data, European/W. Asian data, and S. Hemisphere data. A model for the quasi-biennial oscillation in W-E winds at low latitudes is given. Other variations, such as diurnal (tidal) variations, and S-N winds are dealt with in the review of observational data.
