Book Synopsis A Search for Wave Induced Particle Precipitation from Lightning and Transmitter Sources by : Jon Eric Lundberg

This book was released on 1988 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave induced particle precipitation is introduced and examined for whistlers whose sources are within the plasmapause. The possible correlation between lightning strokes that carry positive charge to the ground and the observed 'Trimpi' events is discussed, sudden phase and/or amplitude shifts of a received VLF signal with gradual return to predisturbed values. The thunderstorm charging mechanisms that lead to the observed charge distribution and the advection of the positively charged cirrus anvil away from the body of the thunderstorm are briefly examined. The comparative current strengths and the relative frequency of positive and negative strokes is studied for different types of thunderstorms. The magnetospheric ducting of the lightning generated whistler wave and the interaction with trapped electrons is examined. The detectable effects the precipitating electrons have on the ionosphere is introduced. Included are testing and design of the x-ray detector and balloon launch considerations. The problems encountered during the x-ray detector's balloon flights are examined. The riometer and x-ray detector data analysis methods are mentioned. The results were negative for the data that was analyzed but the limiting factors severely restricted the usable data. Possible experimental methods are mentioned. Theses. (jhd).

Book Synopsis Global Assessment of Precipitation of Radiation Belt Electrons by Electromagnetic Waves from Lightning by : Erin Selser Gemelos
Download or read book Global Assessment of Precipitation of Radiation Belt Electrons by Electromagnetic Waves from Lightning written by Erin Selser Gemelos and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lightning discharges are well known sources of electromagnetic radiation in the frequency range of a few Hz to many MHz, with the most intense radiation typically being in the range of 5--10 kHz. Electromagnetic waves originating in lightning discharges often propagate through the most densely ionized regions of the Earth's atmosphere and populate the radiation belts. High-energy electrons in this region constitute a hazard to the increasing number of scientific and commercial spacecraft that orbit the Earth, and quantitative understanding of this radiation and its sources and losses are thus important. Electromagnetic whistler waves injected into the radiation belts by lightning discharges can pitch-angle scatter the energetic electrons and cause them to precipitate out of their stably trapped radiation belt orbits and onto the dense upper atmosphere of the Earth. This dissertation examines the detection of lighting-induced energetic electron precipitation via long-term analysis of in-situ observations of drift loss cone fluxes (i.e., fluxes destined to be precipitated over the South Atlantic Anomaly within ~2 hours). The primary measurement tool used is an energetic electron detector (IDP) on board the DEMETER satellite--a French micro-satellite in a sun-synchronous low Earth orbit. Energetic electron flux data are analyzed alongside ground-based lightning data recorded by the National Lightning Detection Network (NLDN) to determine the relationship between drift loss cone fluxes and lightning. While lighting-induced electron precipitation events occur globally, the best region for making in-situ observations of fluctuations in drift loss cone fluxes is over the continental United States. Measurements of VLF wave activity in the typical frequency range of lightning-generated whistler waves (5--10 kHz) on DEMETER show a substantial increase of electromagnetic wave power over the United States, particularly during the northern summer months when lightning activity is at its highest. Analysis of particle precipitation data on the DEMETER spacecraft over a three-year period shows that energetic electron fluxes in the drift loss cone exhibit a seasonal dependence consistent with lightning-induced electron precipitation (LEP) being an important source of loss of such energetic radiation. Over the United States, energetic electron fluxes in the slot region (2

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 344 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
