Available in PDF, EPUB and Kindle. Book excerpt: A formulation is presented for modeling neutral atmosphere structure in an intermediate height region (70-130 km) between given lower and upper models in temperature, pressure, density and constituent gas concentrations and to maintain continuity in the second derivative of temperature and the other properties with respect to height. The method employs temperature as the prime parameter requiring simultaneously a best fit to available temperature data at the intermediate heights and hydrostatic consistency between the nitrogen partial pressures at 70 and 130 km. The method is well suited to upper and lower models that have analytical representations and is developed as the upper model and for polynomially-generated height-latitude cross-sections in the lower region. Attention is given to comparisons between observed and model temperatures and it is found that mid-latitude data (primarily obtained using the incoherent scatter technique) are on average higher than the models due to the requirement to maintain hydrostatic consistency in nitrogen partial pressures between the 70 km and 130 km values of the given lower and upper models. This discrepancy which at present remains an unresolved problem is discussed in the text. Tables of temperature, pressure, and density are included in the report based on the best fit to available data and simultaneously satisfying the constraints of the upper and lower models. Keywords: Temperature; Mesosphere; Pressure; Lower thermosphere; Density; Model atmospheres. (JHD).

Available in PDF, EPUB and Kindle. Book excerpt: The papers presented in this volume have been divided into three main chapters. Firstly Atmospheric Trace Species which is primarily concerned with the construction of a COSPAR International Reference Atmosphere (CIRA -Volume 3) for trace constituents of the middle atmosphere and lower thermosphere. Possible reference models and data were presented on a number of trace species including background stratospheric aerosols, polar stratospheric clouds, methane, nitrous oxide, ozone, water vapor, thermospheric nitric oxide, molecular oxygen airglow emissions, atomic oxygen and atomic hydrogen. Chapter 2 entitled Equatorial Thermosphere and Aeronomy: Models and San Marco Satellite/Ground Based observations reflects the advances made recently in equatorial aeronomy and demonstrate the promise of coordinated measurements using satellite measurements in conjunction with sounding rockets and ground-based experiments. The final chapter, Coupling of Dynamical, Radiative and Chemical Processes in the Middle Atmosphere examines the ozone hole and related atmospheric chemistry and modelling.

Book excerpt: This report provides descriptions of environmental models used in the near-earth environment for the analysis of earth-based and satellite data. Included are models of the ionosphere, atmosphere, radiation belt, Earth's magnetic field, and orbital prediction. These models are used at PL for a variety of purposes, in particular, for the analysis of experimental data obtained from ground based instruments and, where applicable, instruments carried on balloons, rockets, and satellites. Some of the models described here were developed at PL based upon such measurements. For many of the models described here, computer output is provided together with estimates of computer (CPU) times required to generate such output. The computer codes (subroutines) for these models are frequently incorporated into programs used for data analysis and reduction, as well as mission planning. It is hoped that this report will serve as a useful reference for planning such future missions.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Upper Atmosphere Models and Research written by COSPAR. Plenary Meeting and published by Elsevier Science & Technology. This book was released on 1989 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paperback. The 33 papers published were selected from those given at the above Proceedings, and are divided into three chapters. Chapter 1 provides four papers under the heading Up-dating of CIRA 1986. In Chapter 2, entitled Trace Constituents of the Middle and Upper Atmosphere, the papers published go some way toward providing a set of preliminary reference atmospheres of significant trace species of the middle atmosphere and lower thermosphere. These trace species play important roles in controlling the chemistry, radiation balance and circulation patterns of the Earth's stratosphere, mesosphere and thermosphere. The third chapter, The Localized Response of the Lower Thermosphere and Ionosphere at High Latitudes, describes the broad range of recent advances made by theoretical and modelling activities and also reports on experimental investigations using a wide range of methods, ground-based radar, ground-based optical, space-borne in situ and
