Download or read book The D and E Regions written by William Swider and published by . This book was released on 1974 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of the E-region is fairly well understood and even many of the dynamical complications of this region have been successfully modeled on individual bases. Some of the major remaining problems of this region are discussed, in particular the nitric oxide concentration, a gas affecting the ratio of the two major E-region ions, O2(+) and NO(+). The D-region is much simpler than the E-region from a dynamical point of view but extremely much more complex from a chemical standpoint. Recent results from a study of the D-region under bombardment by solar protons is emphasized.
Download or read book On Formulating a Simple D Region Model written by William Swider and published by . This book was released on 1987 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on a body of work that suggests that the effective recombination coefficients in the daytime D-Region are fairly invariant and thus lead to a rather simple solution for the electron concentrations. In addition, a quadratic expression is available for the estimation of electron concentrations at night. The ionization production rate q must be known and incorporated into the chemistry of the D region to determine electron concentrations (e) as a function of altitude. There is some D region research which supports a simple way to determine (e) once q is known. Thus, the daytime effective recombination coefficient, Psi, appears to be relatively insensitive to q and can provide for the determination of (e), (e) = sq rt(q/Psi) under steady-state conditions. For steady-state conditions at night, an equation exists which yields (e) with reasonable accuracy. Keywords: D Region; Ionosphere; Mesosphere. (JHD).

Download or read book The Earth s Ionosphere written by Michael Kelly and published by Elsevier. This book was released on 2012-12-02 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth's Ionosphere: Plasma Physics and Electrodynamics emphasizes the study of plasma physics and electrodynamics of the ionosphere, including many aeronomical influences. The ionosphere is somewhat of a battleground between the earth's neutral atmosphere and the sun's fully ionized atmosphere, in which the earth is embedded. One of the challenges of ionosphere research is to know enough about these two vast fields of research to make sense out of ionospheric phenomena. This book provides insights into how these competing sources of mass, momentum, and energy compete for control of the ionosphere. Some of the topics discussed include the fundamentals of ionospheric plasma dynamics; equatorial plasma instabilities; high-latitude electrodynamics; and instabilities and structure in the high-latitude ionosphere. Throughout this text only the region above 90 km are discussed, ignoring the D region entirely. This publication is a good source of information for students and individuals conducting research on earth’s ionosphere.

Download or read book The Atmosphere and Climate of Mars written by Robert M. Haberle and published by Cambridge University Press. This book was released on 2017-06-29 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Introduction to Atmospheric Chemistry written by Daniel J. Jacob and published by Princeton University Press. This book was released on 1999 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric chemistry is one of the fastest growing fields in the earth sciences. Until now, however, there has been no book designed to help students capture the essence of the subject in a brief course of study. Daniel Jacob, a leading researcher and teacher in the field, addresses that problem by presenting the first textbook on atmospheric chemistry for a one-semester course. Based on the approach he developed in his class at Harvard, Jacob introduces students in clear and concise chapters to the fundamentals as well as the latest ideas and findings in the field. Jacob's aim is to show students how to use basic principles of physics and chemistry to describe a complex system such as the atmosphere. He also seeks to give students an overview of the current state of research and the work that led to this point. Jacob begins with atmospheric structure, design of simple models, atmospheric transport, and the continuity equation, and continues with geochemical cycles, the greenhouse effect, aerosols, stratospheric ozone, the oxidizing power of the atmosphere, smog, and acid rain. Each chapter concludes with a problem set based on recent scientific literature. This is a novel approach to problem-set writing, and one that successfully introduces students to the prevailing issues. This is a major contribution to a growing area of study and will be welcomed enthusiastically by students and teachers alike.
Download or read book Ionospheric Prediction and Forecasting written by Bruno Zolesi and published by Springer Science & Business Media. This book was released on 2013-09-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how to predict and forecast the state of planet Earth’s ionosphere under quiet and disturbed conditions in terms of dynamical processes in the weakly ionized plasma media of the upper atmosphere and their relation to available modern measurements and modelling techniques. It explains the close relationship between the state of the media and the radio wave propagation conditions via this media. The prediction and forecasting algorithms, methods and models are oriented towards providing a practical approach to ionospherically dependent systems design and engineering. Proper understanding of the ionosphere is of fundamental practical importance because it is an essential part of telecommunication and navigation systems that use the ionosphere to function or would function much better in its nonappearance on the Earth and on any planet with an atmosphere.

This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lecmres presented at the Summer Advanced Study Institute, 'Physics and Chemistry of Upper Atmospheres' which was held at the University of Orleans, Orleans, France, during the period July 31 through August 11,1972. One hundred thirty nine persons from 14 different countries attended the Institute. The authors and the publisher have made a special effort for rapid publication of an up-to-date status of the particles, fields, and processes in the earth's magnetosphere, which is an ever changing area. Special thanks are due to the lecturers for their diligent preparation and excellent presentations. The individual lectures and the published papers were deliberately limited; the authors' cooperation in conforming to these specifications is greatly appreciated. The contents of the book are organized by sub ject area rather than in the order in which papers were presented during the Institute. Many thanks are due to Warren Berning, Donald M. Hunten, Edward Llewellyn, J. Ortner, Henry Rishbeth, Harold I Schiff, Lance Thomas, Alister Vallance Jones, and Gilbert Weill, who served as session chairmen during the Institute and contributed greatly to its success by skillfully directing the discussion period in a stimulating manner after each lecture.
