Book Synopsis Global Quantification of Lightning-induced Electron Precipitation Using Very Low Frequency Remote Sensing by : Benjamin Randolph Tucker Cotts
Download or read book Global Quantification of Lightning-induced Electron Precipitation Using Very Low Frequency Remote Sensing written by Benjamin Randolph Tucker Cotts and published by Stanford University. This book was released on 2011 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations of lightning-induced electron precipitation (LEP) events at three geographic regions show characteristics which systematically vary with both longitude and hemisphere. These observations are quantitatively interpreted with the use of a novel model of atmospheric backscatter designed to be used to predict the characteristics of LEP events at any longitude and mid-latitude L-shell by accounting for the effects of precipitating electrons which are backscattered from the atmosphere. The new model of atmospheric backscatter (ABS) is based upon the calculation of ~16,000 individual atmospheric backscatter responses for monoenergetic electron beams with a single incident pitch angle using a Monte Carlo model of atmospheric interactions which tracks the full gyration of each individual precipitating electron around the magnetic field line as it enters the atmosphere, accounting for the dynamic friction force and angular diffusion as well as the production of new electrons via ionization. The ABS model includes the effects of the asymmetric magnetic field in calculations of the pitch angle of backscattered electrons entering the conjugate hemisphere and accounts for the different strength of the magnetic field at conjugate points of the same field line. This magnetic field difference causes the equatorial loss cone angle to vary greatly between hemispheres and with longitude which results in significant and systematic differences in LEP signatures at various locations. A realistic distribution of precipitating electrons is inserted into the ABS model by calculating the energy and pitch angle distribution which results from the resonant interactions of a lightning-initiated magnetospherically reflecting whistler wave with trapped radiation belt particles. This calculation is accomplished by extensive magnetospheric ray-tracing, accounting for Landau damping as well as spatial and temporal dispersion of the whistler wave. This distribution of precipitating electrons is then inserted into the ABS model at three separate longitudes (260 degrees east (1N) and 290 degrees east (2N) in the Northern Hemisphere, and 295 degrees east (2S) in the Southern Hemisphere, corresponding to the Central United States, the East Coast of the United States, and Palmer, Antarctica, respectively) and the deposition results are compared with VLF remote sensing data collected on nearly north-south great circle paths (GCPs) allowing for isolation of longitudinal effects on LEP. Results predicted by the model and confirmed by data indicate that all four primary LEP characteristics exhibit longitudinal and hemispheric dependencies which can be explained in terms of backscatter of precipitating electrons from the atmosphere. The mean observed LEP onset delay exhibits a hemispheric dependence at these longitudes with events in the northern hemisphere delayed by one bounce period relative to direct precipitation and advanced by one-half bounce period in the southern hemisphere. The mean observed onset duration exhibits a longitudinal dependence with events observed at locations 1N and 2S persisting for three bounce periods, and at location 2N for two bounce periods. The amplitude change and recovery time also show a longitudinal and hemispheric dependence based upon the relative sizes of the loss cones at different longitudes with LEP events produced at location 1N consistently larger than at location 2N, and observed recovery times at location 2N longer than at 1N which are still longer than at 2S. All of these results are explained in terms of backscatter of precipitating electrons from the atmosphere and ABS model shows that by accounting for atmospheric backscatter it is possible to accurately predict all the observable characteristics of LEP events. Furthermore, by combining these effects with previously calculated radiation belt electron loss rates due to lightning at a single location, it is possible to estimate the global loss of radiation belt electrons due to lightning.

Available in PDF, EPUB and Kindle. Book excerpt: From July 7 to 12, 2008 in Zelenogradsk, a cosy resort on the bank of the Baltic Sea near Kaliningrad in Russia, the 1st International Conference “Atmosphere, Ionosphere, Safety (AIS-2008)” has been carried out. The State Russian University of I. Kant, Semenov Institute of chemical physics of the Russian Academy of Sciences, Pushkov Institute of terrestrial magnetism and radio-waves propagation of the Russian Academy of Sciences, and Russian Committee on Ball Lightning (BL) have acted as organizers of the conference. Financial support was made by Russian Fund of Fundamental Research Project N. 08-03-06041 and European Of?ce of Aerospace Research and Development Grant award FA8655-08-1-5052. The International conference “Atmosphere, Ionosphere, Safety” (AIS-2008) was devoted to (i) the analysis of the atmosphere–ionosphere response on natural and man-made processes, the reasons of occurrence of the various accompanying geophysical phenomena, and an estimation of possible consequences of their in?uence on the person and technological systems; (ii) the study of the monitoring possibility and search of the ways for the risk level decrease. Discussion of the physical and chemical processes accompanying the observable geophysical p- nomena was undertaken. One can see from a list of the Conference sections that questions of safety took only rather modest place, so main topics of the Conference became discussion of processes taking place in the atmosphere, ionosphere and methods of monitoring these processes.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the 1989 Crafoord Symposium organized by the Royal Swedish Academy of Sciences. The scientific field for the Crafoord Prize of 1989 was decided in 1988 by the Academy to be Magnetospheric Physics. On September 27,1989 the Academy awarded the 1989 Crafoord Prize to Professor J. A. Van Allen, Iowa City, USA "for his pioneer work in space research, in particular for the discovery of the high energy charged particles that are trapped in the Earth's magnetic field and form the radiation belts -often called the Van Allen belts - around the Earth". The subject for the Crafoord Symposium, which was held on September 28-29 at the Royal Swedish Academy of Sciences in Stockholm, was Magnetospheric Physics, Achievements and Prospects. Some seventy of the world's leading scientists in magnetospheric physics (see list of participants) were invited to the Symposium. The program contained only invited papers. After the ?resentation of the Crafoord Prize Laureate, Prof. J . A. Van Allen, and his specially invited lecture: "Active Experiments in Magnetospheric Physics" follows in these proceedings two papers on the achievements of magnetospheric research hitherto. The main part of the proceedings (8 papers) deal with the main theme of the Symposium: How we shall carry on magnetospheric research in the future. The Symposium was organized by five members of the Academy representing the field of space physics: Lars Block (Stockholm), Rolf Bostrom (Uppsala), Kerstin Fredga (Stockholm), Carl-Gunne Fiilthammar (Stockholm) and Bengt Hultqvist (Kiruna, Chairman).

Book Synopsis Modeling Magnetospheric Plasma by : T. E. Moore
Download or read book Modeling Magnetospheric Plasma written by T. E. Moore and published by American Geophysical Union. This book was released on 1988 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 44. Existing models of the plasma distribution and dynamics in magnetosphere / ionosphere systems form a patchwork quilt of different techniques and boundaries chosen to define tractable problems. With increasing sophistication in both observational and modeling techniques has come the desire to overcome these limitations and strive for a more unified description of these systems. On the observational side, we have recently acquired routine access to diagnostic information on the lowest energy bulk plasma, completing our view of the plasma and making possible comparisons with magnetohydrodynamic calculations of plasma moments. On the theoretical side, rising computational capabilities and shrewdly designed computational techniques have permitted the first attacks on the global structure of the magnetosphere. Similar advances in the modeling of neutral atmospheric circulation suggest an emergent capability to globally treat the coupling between plasma and neutral gases. Simultaneously, computer simulation has proven to be a very useful tool for understanding magnetospheric behaviors on smaller space and time scales.

Book Synopsis The Dynamic Loss of Earth's Radiation Belts by : Allison Jaynes
Download or read book The Dynamic Loss of Earth's Radiation Belts written by Allison Jaynes and published by Elsevier. This book was released on 2019-09-05 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dynamic Loss of Earth's Radiation Belts: From Loss in the Magnetosphere to Particle Precipitation in the Atmosphere presents a timely review of data from various explorative missions, including the Van Allen Probes, the Magnetospheric Multiscale Mission (which aims to determine magnetopause losses), the completion of four BARREL balloon campaigns, and several CubeSat missions focusing on precipitation losses. This is the first book in the area to include a focus on loss, and not just acceleration and radial transport. Bringing together two communities, the book includes contributions from experts with knowledge in both precipitation mechanisms and the effects on the atmosphere. There is a direct link between what gets lost in the magnetospheric radiation environment and the energy deposited in the layers of our atmosphere. Very recently, NASA's Living With a Star program identified a new, targeted research topic that addresses this question, highlighting the timeliness of this precise science. The Dynamic Loss of Earth's Radiation Belts brings together scientists from the space and atmospheric science communities to examine both the causes and effects of particle loss in the magnetosphere. - Examines both the causes and effects of particle loss in the magnetosphere from multiple perspectives - Presents interdisciplinary content that bridges the gap, through communication and collaboration, between the magnetospheric and atmospheric communities - Fills a gap in the literature by focusing on loss in the radiation belt, which is especially timely based on data from the Van Allen Probes, the Magnetospheric Multiscale Mission, and other projects - Includes contributions from various experts in the field that is organized and collated by a clear-and-consistent editorial team
