This book was released on 2021-12-07 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: In 2010, NASA and the National Science Foundation asked the National Research Council to assemble a committee of experts to develop an integrated national strategy that would guide agency investments in solar and space physics for the years 2013-2022. That strategy, the result of nearly 2 years of effort by the survey committee, which worked with more than 100 scientists and engineers on eight supporting study panels, is presented in the 2013 publication, Solar and Space Physics: A Science for a Technological Society. This booklet, designed to be accessible to a broader audience of policymakers and the interested public, summarizes the content of that report.
Download or read book The Trough in the Daytime F Layer A Macroscopic Effect of Ionospheric Magnetospheric Convection written by J. A. Whalen and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The daytime F layer through is a major result of ionospheric-magnetospheric convection, appearing in the winter high latitude ionosphere as a continuous band thousands of kilometers in extent in which the daytime F layer electron density is depleted, often by an order of magnitude. As observed by a global array of ionospheric sounders during solar maximum, the trough occurs in regions of sunward convection, in the morning corresponding to the dawn cell and in the afternoon corresponding to the dusk cell. The formation of the trough is consistent with the transport of low density nighttime plasma into the day sector where it displaces high density daytime plasma, although other mechanisms such as ion chemical effects may also play a role.

Advisory Group for Aerospace Research and Development. Electromagnetic Wave Propagation Panel. Symposium and published by . This book was released on 1989 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communications, Navigation and Surveillance Systems operating in/through the aerospace EM propagation environment are affected by the state/variability of the propagation media. The range of phenomena need for their elucidation, observations and analysis on a global scale since only an understanding of the complex global interaction can improve the means of predictability and assessment of localized phenomena suggesting methods for mitigating adverse propagation conditions. With this goal, ionospheric dynamics, ionosphere/magnetosphere and ionosphere/atmosphere interactions were analysed and discussed at this symposium.
Download or read book The Magnetotelluric Method written by Alan D. Chave and published by Cambridge University Press. This book was released on 2012-04-26 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics, from the salient physics and its mathematical representation to practical implementation in the field, data processing, modeling and geological interpretation. Electromagnetic induction in 1-D, 2-D and 3-D media is explored, building from first principles, and with thorough coverage of the practical techniques of time series processing, distortion, numerical modeling and inversion. The fundamental principles are illustrated with a series of case histories describing geological applications. Technical issues, instrumentation and field practices are described for both land and marine surveys. This book provides a rigorous introduction to magnetotellurics for academic researchers and advanced students, and will be of interest to industrial practitioners and geoscientists wanting to incorporate rock conductivity into their interpretations.
Download or read book The Effect of Ionospheric Outflow on the Dynamics of Magnetospheric Convection written by Oliver J. Brambles and published by . This book was released on 2012 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ionosphere is an important source of plasma in the magnetosphere, especially during geomagnetic storms. While satellite data has confirmed this population of ions, their effect on the dynamics of the magnetosphere-ionosphere (MI) system is not well understood. Global simulations play an important role in the understanding of geospace and allow the response of the MI system to ionospheric ions to be systematically investigated. This thesis focuses on the effect of ionospheric outflow on the strength and mode of magnetospheric convection. Models for transversely accelerated O+ outflow are implemented into a multifluid adaptation of the Lyon-Fedder-Mobarry (LFM) global simulation using empirical relationships which relate downward electromagnetic and particle power to an upwards flux of O+ ions. The effect of a cusp O+ ouflow on the strength of magnetospheric convection, as measured by the cross polar cap potential (CPCP), is examined for a moderate geomagnetic storm. The response of the CPCP to the O+ outflow is found to depend upon two competing factors. The reduction in ionospheric conductance when outflow is present increases the CPCP and the inflation of the magnetosphere due to an O+-enhanced ring current decreases the CPCP. Through controlled global simulations of geopsace it is shown that ionospheric O+ ions can generate 2-4 hour, planetary-scale, sawtooth oscillations. If the outflow fluence is above a threshold, convection transitions from a quasi-steady mode to the quasi-periodic sawtooth mode. The O+ ions promote sawtooth oscillations by reducing the nightside reconnection potential, which results in the increase of open flux to an unstable level, and by generating an outward force balance in the plasma sheet, which stretches the nightside field lines and facilitates plasmoid formation. This behavior has not previously been captured by a global simulation and represents a major breakthrough in the understanding of the dynamics of convection in the magnetosphere.

This book was released on 2013-05-03 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 181. Filling the need for a 20-year lag in substantial consideration of the midlatitude ionosphere, this volume focuses on work that takes advantage of GPS and UV imaging from satellites over the past decade, two methods that have profoundly transformed our understanding of this stratum of the atmosphere. Its interdisciplinary content brings together researchers of the solar wind, magnetosphere, ionosphere, thermosphere, polar and equatorial ionospheres, and space weather. Modeling and assimilative imaging of the ionosphere and thermosphere show for the first time the complex and global impact of midlatitude ionospheric storms. The editors invited the leading experts in the following areas to contribute the chapters herein: Characterization of Midlatitude Storms Electric Field Coupling From the Heliosphere and Inner Magnetosphere Thermospheric Control of the Midlatitude Ionosphere Ionospheric Irregularities Experimental Methods and New Techniques These themes were chosen to create a path for understanding the midlatitude ionosphere. They continue to be largely valid and represent a coherent division of the subject matter. They will be critical for understanding space weather during the upcoming solar maximum. This book was inspired by the Chapman Conference of the same name held January 2007.
