This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron densities and temperatures as well as omnidirectional fluxes of hyperthermal positive ions (E > 28 eV) were measured by means of spherical Langmuir probes aboard INJUN 5 at altitudes > 2000 km during a major geomagnetic storm. The electron density in the mid-latitude trough decreased and the temperatures increased during the early phases of the storm. As the storm progressed the trough's position moves equatorward with plasma depletions being observed to an invariant latitude of 40 deg during the early recovery phase. The latitude of the transition between heavy and light ion dominance also moved equatorward, but recovered at a rate slower than that of the electron trough's position. Hyperthermal ions detected in the vicinity of the trough were ring current particles reaching to the satellite's altitude. The minimum thermal electron densities in the trough were found to be within 1 deg of latitude of the maximum ring current flux. Maximum electron temperatures were measured several degrees equatorward of this position. INJUN 5 electron temperatures are compared with those measured by Alouette 2 over the reported positions of SAR arcs. The observations are also used to further evaluate a method developed for calculating the position of the ring current using ground magnetic fluctuations.

Available in PDF, EPUB and Kindle. Book excerpt: A model is presented for the thickness of the electron density profile in the region above the F layer maximum. The model varies with time and solar conditions; it is specified by observations or predictions of the height of the F layer maximum; and it is independent of latitude. Results indicate that a mean thickness parameter can be estimated to within about 15 percent and that there is a useful reduction in the day to day variability.

Available in PDF, EPUB and Kindle. Book excerpt: James L. Burch·C. Philippe Escoubet Originally published in the journal Space Science Reviews, Volume 145, Nos 1–2, 1–2. DOI: 10. 1007/s11214-009-9532-7 © Springer Science+Business Media B. V. 2009 The IMAGE and CLUSTER spacecraft have revolutionized our understanding of the inner magnetosphere and in particular the plasmasphere. Before launch, the plasmasphere was not a prime objective of the CLUSTER mission. In fact, CLUSTER might not have ever observed this region because a few years before the CLUSTER launch (at the beginning of the 1990s), it was proposed to raise the perigee of the orbit to 8 Earth radii to make multipoint measu- ments in the current disruption region in the tail. Because of ground segment constraints, this proposal did not materialize. In view of the great depth and breadth of plasmaspheric research and numerous papers published on the plasmasphere since the CLUSTER launch, this choice certainly was a judicious one. The fact that the plasmasphere was one of the prime targets in the inner magnetosphere for IMAGE provided a unique opportunity to make great strides using the new and comp- mentary measurements of the two missions. IMAGE, with sensitive EUV cameras, could for the rst time make global images of the plasmasphere and show its great variability d- ing storm-time. CLUSTER, with four-spacecraft, could analyze in situ spatial and temporal structures at the plasmapause that are particularly important in such a dynamic system.
Download or read book Ionospheric Space Weather written by Timothy Fuller-Rowell and published by John Wiley & Sons. This book was released on 2016-12-05 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the outcome of an American Geophysical Union Chapman Conference on longitude and hemispheric dependence of ionospheric space weather, including the impact of waves propagating from the lower atmosphere. The Chapman Conference was held in Africa as a means of focusing attention on an extensive geographic region where observations are critically needed to address some of the fundamental questions of the physical processes driving the ionosphere locally and globally. The compilation of papers from the conference describes the physics of this system and the mechanisms that control ionospheric space weather in a combination of tutorial-like and focused articles that will be of value to the upper atmosphere scientific community in general and to ongoing global magnetosphere-ionosphere-thermosphere (MIT) modeling efforts in particular. A number of articles from each science theme describe details of the physics behind each phenomenon that help to solve the complexity of the MIT system. Because this volume is an outcome of the research presented at this first space science Chapman Conference held in Africa, it has further provided an opportunity for African scientists to communicate their research results with the international community. In addition, the meeting and this conference volume will greatly enhance the space science education and research interest in the African continent and around the world. Ionospheric Space Weather includes articles from six science themes that were discussed at the Chapman Conference in 2012. These include: Hemispherical dependence of magnetospheric energy injection and the thermosphere-ionosphere response Longitude and hemispheric dependence of storm-enhanced densities (SED) Response of the thermosphere and ionosphere to variability in solar radiation Longitude spatial structure in total electron content and electrodynamics Temporal response to lower-atmosphere disturbances Ionospheric irregularities and scintillation Ionospheric Space Weather: Longitude Dependence and Lower Atmosphere Forcing will be useful to both active researchers and advanced graduate students in the field of physics, geophysics, and engineering, especially those who are keen to acquire a global understanding of ionospheric phenomena, including observational information from all longitude sectors across the globe.
Download or read book Large Amplitude Irregularities at Low Latitudes in the Topside Ionosphere written by W. J. Burke and published by . This book was released on 1977 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations from the high resolution spherical electrostatic analyzer experiment aboard ISIS I have been used to study large amplitude irregularities at low latitudes in the topside ionosphere. The irregularities appeared as plasma depletions near the magnetic equator and were observed up to satellite apogee (3500 km). The altitude-local time distribution of the depletions was such that those at altitudes greater than 2000 km were found only in the post-midnight sector. This result agrees with the predictions of a simple MHD model for plasma bubbles drifting under the influence of gravity-buoyancy forces. (Author).
