Book Synopsis 1978 Diffuse Auroral Boundaries and a Derived Auroral Boundary Index by : M. S. Gussenhoven
Download or read book 1978 Diffuse Auroral Boundaries and a Derived Auroral Boundary Index written by M. S. Gussenhoven and published by . This book was released on 1982 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: DMSP/F2 and F4 precipitating electron data are used to determine statistically the systematic variations of the equatorward boundary with Kp as a function of local time. The boundaries were chosen by hand for every DMSP/F2 satellite pass in 1978. These in turn are used to assess an algorithm developed to choose the boundaries automatically. From the statistical variations each boundary is projected to a midnight boundary. The projected midnight boundary served as an index of auroral activity-the Auroral Boundary Index. Listing of the 1978 hand- and computer-chosen boundaries and the Auroral Boundary Index for 1978 are included in appendices.

Book Synopsis Derivation of a Self-Consistent Auroral Oval Model Using the Auroral Boundary Index by : Keith A. Anderson

This book was released on 2004-06-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The position and intensity of the auroral oval has many implications for the Air Force from determining the effects of incoming electron flux on DoD systems to modeling the ionosphere to exploit current HF communications capabilities. The auroral morphology is a good indicator of the level at which space weather and its near-Earth consequences are occurring, and thus it is important to develop an auroral prediction model. However, since no purely physics-based models exist to describe the temporal and spatial evolution of the auroral zone, space weather practitioners and researchers are forced to produce statistical representations, "organized" by some relevant geophysical parameter. Currently, the most widely used model is the Hardy et al. (1985) auroral oval model, which is binned according to the Kp index. The Kp index is a mid-Iatitude measure of planetary geomagnetic activity, and was presumed to be well- correlated to the size and shape of the auroral region. However, subsequent research has shown that Kp is probably not the best binning parameter. This study used the Auroral Boundary Index (ABI) to parameterize the statistics of the auroral oval location since it is a measurement of the electron fluxes computed directly from sensors aboard the DMSP satellites. Thus, the current work represents a move toward a more self- consistent-and presumably more accurate-climatological representation of the auroral oval boundaries. This was accomplished by recreating the process performed by Hardy et al., substituting the ABI for the Kp index and deriving an entirely new set of auroral ovals based on almost 11 years ofDMSP data from the F8 and F9 satellites. To quantitatively assess the differences between the two models, electron flux values were compared to actual DMSP data of individual satellite passes. Preliminary findings suggest that the new ABI auroral ov

Book Synopsis The Cluster and Phoenix Missions by : C.P. Escoubet
Download or read book The Cluster and Phoenix Missions written by C.P. Escoubet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cluster was one of the two missions - the other being the Solar and Heliospheric Observatory (SOHO) - constituting the Solar Terrestrial Science Programme (STSP), the first `cornerstone' of ESA's Horizon 2000 Programme. After the catastrophic Ariane-5 accident on 4 June 1996 which destroyed the four Cluster spacecraft, the European Space Agency Science Programme Committee gave approval to refurbish the spare Cluster spacecraft and make it ready for flight. This new spacecraft, considered to be the first of a new fleet, is called Phoenix. In the meantime various options to repeat the Cluster four-point measurements are being studied. Since Phoenix, as the fifth Cluster spacecraft, will be equipped with the spare Cluster experiments, the instrumentation articles in this book are still appropriate to the new mission. Furthermore, the objectives of the recovery mission, the ground systems, the ground observation program and the theory and modelling efforts all remain unchanged. Thus this series of articles will continue to be essential to the Cluster community and to the general scientific community as the recovery mission is implemented.
Book Synopsis Low-Frequency Waves in Space Plasmas by : Andreas Keiling
Download or read book Low-Frequency Waves in Space Plasmas written by Andreas Keiling and published by John Wiley & Sons. This book was released on 2016-02-10 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-frequency waves in space plasmas have been studied for several decades, and our knowledge gain has been incremental with several paradigm-changing leaps forward. In our solar system, such waves occur in the ionospheres and magnetospheres of planets, and around our Moon. They occur in the solar wind, and more recently, they have been confirmed in the Sun’s atmosphere as well. The goal of wave research is to understand their generation, their propagation, and their interaction with the surrounding plasma. Low-frequency Waves in Space Plasmas presents a concise and authoritative up-to-date look on where wave research stands: What have we learned in the last decade? What are unanswered questions? While in the past waves in different astrophysical plasmas have been largely treated in separate books, the unique feature of this monograph is that it covers waves in many plasma regions, including: Waves in geospace, including ionosphere and magnetosphere Waves in planetary magnetospheres Waves at the Moon Waves in the solar wind Waves in the solar atmosphere Because of the breadth of topics covered, this volume should appeal to a broad community of space scientists and students, and it should also be of interest to astronomers/astrophysicists who are studying space plasmas beyond our Solar System.
