Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to describe and discuss the aurora as an optical phenomenon, one which can be observed by the naked eye as well as with more sensitive optical detectors. It continues the tradition of study ing that impressive and imaginative play of nature, the northern lights, seen and discussed by the Greek philosphers as early as the sixth century B.c. Today the study of the optical aurora is only one of many ways of acquiring information about a major phenomenon: the ejection of plasma from the sun, the interaction of this plasma with the geomagnetic field and the injection of fast particles into the earth's atmosphere. of the optical aurora is justified by the Hence, the separate treatment particular scientific approach: detection and interpretation of electro magnetic radiation, approximately in the 1000-100000 A region, produc ed through interaction between the auroral particles and the earth's atmosphere. Other techniques, such as radio observations, X-ray observations, direct particle detections from rockets and satellites, studies of magnetic storms, and measurements of the magnetic field and plasma properties in the magnetosphere, are as important or more important than the classical way of studying the optical aurora. Nevertheless, it was felt worthwhile to treat the optical aurora in a separate book, perhaps mainly because today one author cannot master the whole subject with sufficient competence. This book is thus one volume in a series of books giving a more complete picture of physics and chemistry in space.

Book Synopsis In the Light of the Aurora by : Network for Groundbased Optical Auroral Research in the Artic Region
Download or read book In the Light of the Aurora written by Network for Groundbased Optical Auroral Research in the Artic Region and published by Nordic Council of Ministers. This book was released on 2009 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aurora, or northern lights, is the most variable light phenomenon in the sky and the result of physical processes taking place in near-Earth space. The colours, shapes, intensities, locations and movements of auroral forms give us information about these processes. Ground-based optical studies are superior for high-resolution measurements and to distinguish temporal and spatial effects. Arctic Europe is a most convenient place to study the aurora. Many instruments and research facilities have been placed here. The Network for Groundbased Optical Auroral Research in the Arctic Region is supported by the Nordic Council of Ministers and consists of all research institutions in northern Norway, Sweden, Finland and on theKola Peninsula active in optical auroral research. This reportintroduces optical aurora and optical research methods, research institutions and research infrastructure. It also describes the activities of the network: workshops, mobility programme and scientific results.

Book Synopsis Rocketborne Measurements of Optical Emissions from the Auroral E-layer by : Roger A. Van Tassel
Download or read book Rocketborne Measurements of Optical Emissions from the Auroral E-layer written by Roger A. Van Tassel and published by . This book was released on 1982 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of the AFGL Auroral-E Program is to develop a system to specify the electron density in the auroral E-layer by remote sensing of optical emissions. The first step in meeting this objective was a careful input-output experiment conducted in Alaska during March 1981. This experiment included satellite measurements of the source particle stream; rocket measurements of the optical emissions, electron and proton fluxes and electron, neutral and ion densities, neutral winds and electromagnetic fields; airborne measurements to provide data to assess the auroral and ionospheric conditions prior to and during launch; and incoherent scatter radar measurements to provide neutral wind, electric field and electron density data. These data will be used to establish a quantitative relationship among the precipitating particles, the resulting electron density profiles and the optical emissions from several species in the continuous or diffuse aurora. This report gives the results of the rocket-borne filter photometer experiment.

Download or read book Dayside Magnetosphere Interactions written by Qiugang Zong and published by John Wiley & Sons. This book was released on 2020-04-07 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring the processes and phenomena of Earth's dayside magnetosphere Energy and momentum transfer, initially taking place at the dayside magnetopause, is responsible for a variety of phenomenon that we can measure on the ground. Data obtained from observations of Earth’s dayside magnetosphere increases our knowledge of the processes by which solar wind mass, momentum, and energy enter the magnetosphere. Dayside Magnetosphere Interactions outlines the physics and processes of dayside magnetospheric phenomena, the role of solar wind in generating ultra-low frequency waves, and solar wind-magnetosphere-ionosphere coupling. Volume highlights include: Phenomena across different temporal and spatial scales Discussions on dayside aurora, plume dynamics, and related dayside reconnection Results from spacecraft observations, ground-based observations, and simulations Discoveries from the Magnetospheric Multiscale Mission and Van Allen Probes era Exploration of foreshock, bow shock, magnetosheath, magnetopause, and cusps Examination of similar processes occurring around other planets The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the editors

Download or read book Aurora written by A.V. Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades auroral science has developed from a somewhat mysterious and imprecise specialty into a discipline central in the study of the ionosphere and magnetosphere. The investigation of aurora unites scientists with very different backgrounds and interests so that it is difficult to write a self-contained account of the field in a book of reasonable length. In this work I have attempted to include those aspects of theory which I have found valuable in predicting the effects on the atmosphere of auroral particle precipitation. In addition I have attempted to describe the techniques of observation with particular emphasis on optical methods which have been useful. While the aeronomy of aurora has been regarded as central, the mechanisms by which particles are accelerated and precipitated into the atmosphere is of no less interest. This aspect of the subject has however been treated in a briefer fashion since it is a part of the immense and rapidly developing field of magnetospheric science. Generally I have attempted to provide a coherent introduction to auroral science with an emphasis on relatively simple physical interpretations and models. References are given to enable the reader to find more extensive or rigorous discussions of particular topics. A fairly complete, quantitative atlas of the auroral spectrum is included.

Book Synopsis Deploying and Managing IP Over WDM Networks by : Joan Serrat
Download or read book Deploying and Managing IP Over WDM Networks written by Joan Serrat and published by Artech House. This book was released on 2003 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although IP and WDM technologies are expected to become the dominant network technologies, they will be introduced gradually to complement and replace ATM and SDH network solutions. This text reviews and researches results for the deployment and management of IP over WDM networks with guaranteed service level agreements. Design details cover the integrated management requirements and architectures needed to ensure direct and seamless deployment and integration of IP and WDM. Verification of the management and networking concepts has been performed on a research testbed built from WDM rings and IP routing equipment as past of the WINMAN project, which is a European Union-sponsored research project. The volume concludes with an outlook on the expected evolutions of network management and the deployment of optical networks.
