The book is devoted to radio occultation (RO) remote sensing of the earth’s atmosphere and ionosphere as a global method of monitoring. This technique used the radio links satellite-to-satellite when a satellite-receiver setting or rising behind the earth’s atmosphere is relative to a satellite - emitter of radio waves. During setting the radio ray perigee moves through the ionosphere and ionosphere. Atmospheric and ionospheric effects arise in most cases owing to influence of a zone near the radio ray perigee and cause significant variations of the amplitude, phase, and frequency of the radio waves. These variations enable determination of the altitude profiles of temperature, pressure, refractivity, density, humidity and turbulence in the atmosphere, distribution of the electron density in the ionosphere, and the wave phenomena at different altitudes with a global coverage. The aim of this book consists of the systematic description of the different approaches, results of investigation and perspectives of the RO remote sensing as a tool for investigations of the atmosphere and ionosphere.

Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.

A quantitative yet accessible introduction to remote sensing techniques, this new edition covers a broad spectrum of Earth science applications.

Introduction to Satellite Remote Sensing: Atmosphere, Ocean and Land Applications is the first reference book to cover ocean applications, atmospheric applications, and land applications of remote sensing. Applications of remote sensing data are finding increasing application in fields as diverse as wildlife ecology and coastal recreation management. The technology engages electromagnetic sensors to measure and monitor changes in the earth's surface and atmosphere. The book opens with an introduction to the history of remote sensing, starting from when the phrase was first coined. It goes on to discuss the basic concepts of the various systems, including atmospheric and ocean, then closes with a detailed section on land applications. Due to the cross disciplinary nature of the authors' experience and the content covered, this is a must have reference book for all practitioners and students requiring an introduction to the field of remote sensing. - Provides study questions at the end of each chapter to aid learning - Covers all satellite remote sensing technologies, allowing readers to use the text as instructional material - Includes the most recent technologies and their applications, allowing the reader to stay up-to-date - Delves into laser sensing (LIDAR) and commercial satellites (DigitalGlobe) - Presents examples of specific satellite missions, including those in which new technology has been introduced

Space Radio Science deals with the theory and practice of space communications with Earth's satellites and interplanetary probes, interstellar radio communications in our galaxy, and the effects of gravitational fields on propagating radio waves. The text describes a method of radio occultation used to monitor planetary atmosphere and ionosphere. The author considers remote sensing of circumsolar and interplanetary plasmas, as well as of the Earth and other planets in the solar system. The book provides a comprehensive analysis of radiophysical problems and methods, as well as the benefits of various spacecraft and radio signals. It looks at problems such as gravitational pull and its effect on the propagation of radio waves. This monograph is ideal for radio-physicists, engineers and students in space radiophysics, remote sensing, propagation of radio waves and space communications.

This volume continues presentation of the proceedings of a NATO Advanced Research Workshop (ARW) held at Rabat, Morocco on the 17-19th of November 2005 entitled Remote Sensing of the Atmosphere for Environmental Security. Coverage includes a review of recent and upcoming experimental satellite measurements of the Earth’s atmosphere, characterisation of pollution in urban areas and the growing lack of water in many countries of the Mediterranean area, and more.

Theoretical foundations of atmospheric remote sensing are electromagnetic theory, radiative transfer and inversion theory. This book provides an overview of these topics in a common context, compile the results of recent research, as well as fill the gaps, where needed. The following aspects are covered: principles of remote sensing, the atmospheric physics, foundations of the radiative transfer theory, electromagnetic absorption, scattering and propagation, review of computational techniques in radiative transfer, retrieval techniques as well as regularization principles of inversion theory. As such, the book provides a valuable resource for those who work with remote sensing data and want to get a broad view of theoretical foundations of atmospheric remote sensing. The book will be also useful for students and researchers working in such diverse fields like inverse problems, atmospheric physics, electromagnetic theory, and radiative transfer.

Written by a researcher at the forefront of the field, this first comprehensive account of magnetoseismology conveys the physics behind these movements and waves, and explains how to detect and investigate them. Along the way, it describes the principles as applied to remote sensing of near-Earth space and related remote sensing techniques, while also comparing and intercalibrating magnetoseismology with other techniques. The example applications include advanced data analysis techniques that may find wider used in areas ranging from geophysics to medical imaging, and remote sensing using radar systems that are of relevance to defense surveillance systems. As a result, the book not only reviews the status quo, but also anticipates new developments. With many figures and illustrations, some in full color, plus additional computational codes for analysis and evaluation. Aimed at graduate readers, the text assumes knowledge of electromagnetism and physical processes at degree level, but introductory chapters will provide an overview of the relevant plasma physics and magnetospheric physics. The book will thus be of interest to entry-level and established researchers in physics of the Earth's magnetosphere and ionosphere, as well as to students, academics and scientifically literate laypersons with an interest in understanding space weather processes and how these relate to the dynamic behavior of near-Earth space.
