This book was released on 1988 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to determine the relative (compared to the Ap index) utility of global hemispheric power (PPE), as measured by the NOAA/TIROS satellite Total Energy Detector (TED) system, in describing magnetospherically induced upper thermospheric density perturbations. This was accomplished using satellite accelerometer, satellite orbital, Goettingen Ap, and PPE data from the geomagnetically active period of March 20th to April 10th, 1979. The first part of the study used Air Force Geophysics Laboratory (AFGL) satellite accelerometer thermospheric density data to determine the correlation between it and the PPE. This was then compared to the density data correlation with the Goettingen Ap. the data was scaled to optimize the meaning and linearity of the correlation coefficients and to emphasize any density fluctuations due to geomagnetic variations. The time series cross-correlation produced about a 6-hour lagged response in obtaining maximum correlation. (rh).

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 1975 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric densities are computed from analysis of Doppler beacon satellite data. Modifications to Doppler beacon data processing program CELEST necessary for this study are described. Results obtained for satellites DB-7(6382), DB-8(6727), and DB-9(6928) are found to be in good agreement with those obtained by analysis of skin track data for the same satellites using program CADNIP.

Download or read book Modeling the Ionosphere Thermosphere written by J. D. Huba and published by John Wiley & Sons. This book was released on 2014-03-17 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 201. Modeling the Ionosphere-Thermosphere System brings together for the first time a detailed description of the physics of the IT system in conjunction with numerical techniques to solve the complex system of equations that describe the system, as well as issues of current interest. Volume highlights include discussions of: Physics of the ionosphere and thermosphere IT system, and the numerical methods to solve the basic equations of the IT system The physics and numerical methods to determine the global electrodynamics of the IT system The response of the IT system to forcings from below (i.e., the lower atmosphere) and from above (i.e., the magnetosphere) The physics and numerical methods to model ionospheric irregularities Data assimilation techniques, comparison of model results to data, climate variability studies, and applications to space weather Providing a clear description of the physics of this system in several tutorial-like articles, Modeling the Ionosphere-Thermosphere System is of value to the upper atmosphere science community in general. Chapters describing details of the numerical methods used to solve the equations that describe the IT system make the volume useful to both active researchers in the field and students.
Download or read book An Investigation of Atmospheric Density Between Altitudes of 180 Km and 300 Km written by Leonard L. DeVries and published by . This book was released on 1966 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: A knowledge of atmospheric density and its variation at satellite altitudes is needed for operational support of several military activities. Atmospheric density data computed from the decay rates of more than 40 satellites orbited during a five-year period were analyzed during this investigation. Multiple regression equations were derived to specify the density at 10-km intervals at altitudes from 180 to 300 km as a function of solar activity, time of day, time of year, and combinations of these variables. Density values depicted by these regression equations were then compared with density data which had not been used during the derivation of the equations. The results of this investigation indicate that multiple regression analysis and the associated screening procedure can produce equations from which computed density values are in close agreement with observed density data. The results lead to a conclusion that no single density model can meet all needs. These results also indicate that characteristics of a density model should be selected to fit the purpose for which the model is intended. Four possible density models designed for different purposes are suggested. (Author).

Download or read book Ionospheric and Thermospheric Studies written by COSPAR. Plenary Meeting and published by Elsevier Science & Technology. This book was released on 1992 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers presented at these meetings provide an updated review of the area and also cover a wide range of current research topics. This volume contains 46 selected papers covering the whole spectrum of modelling approaches, including analytical, empirical, semi-empirical and numerical models. A proportion of the papers deal with the energetics, dynamics and composition of just the thermosphere, whilst others are concerned with ionospheric behaviour at low, middle and high latitudes. Coupling phenomena figure prominently and numerical simulations are presented to show the coupling processes, feedback mechanisms and time delays associated with the interactions between the magnetosphere and ionosphere, the magnetosphere and thermosphere, and the mid-latitude ionosphere and plasmasphere.
