Available in PDF, EPUB and Kindle. Book excerpt: Using the method of Rush and Gibbs (1973), weighted means of observed values have been used to update the global prediction of f(o)F2, which are based on monthly median values derived from the Institute of Telecommunications Sciences model (1969). This procedure improved the predictions for magnetically quiet periods, for times near minimum of the solar cycle phase, and for the equinoctial months. Furthermore, a closer grid of ionosonde stations resulted in reducing the error in the f(o)F2 prediction. For the method of Rush and Gibbs (1973) to be operationally successful in global predictions of f(o)F2 however, a closer grid of ionosondes than is presently available is needed. (Author).

Book Synopsis Ionospheric Prediction and Forecasting by : Bruno Zolesi
Download or read book Ionospheric Prediction and Forecasting written by Bruno Zolesi and published by Springer Science & Business Media. This book was released on 2013-09-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how to predict and forecast the state of planet Earth’s ionosphere under quiet and disturbed conditions in terms of dynamical processes in the weakly ionized plasma media of the upper atmosphere and their relation to available modern measurements and modelling techniques. It explains the close relationship between the state of the media and the radio wave propagation conditions via this media. The prediction and forecasting algorithms, methods and models are oriented towards providing a practical approach to ionospherically dependent systems design and engineering. Proper understanding of the ionosphere is of fundamental practical importance because it is an essential part of telecommunication and navigation systems that use the ionosphere to function or would function much better in its nonappearance on the Earth and on any planet with an atmosphere.

Book Synopsis The Prediction of Ionospheric Conditions by : G.S. Ivanov-Kholodny
Download or read book The Prediction of Ionospheric Conditions written by G.S. Ivanov-Kholodny and published by Springer. This book was released on 1986-08-31 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ionosphere of the Earth has been actively studied since the 1920's, following the discovery of ground radio-sounding. By means of this method results were ohtained by an international network of ionospheric stations, in particular, by the successful implementation of a number of rigorously planned international scientific research programs,'" enabling the collection of extensive experimental material on some of the most important parameters of the ionosphere - the critical freLjuencies of E-, Fl and F2-layers. Comprehensive analyses of these observation data give a fairly complete picture of the various changes taking place in the principal ionospheric layers at different points on our globe. Another important aspect of the study of the ionosphere, which has been in progress for the past three decades, is an extensive program of in situ determinations of the various physical parameters - first using rockets, and subsequently artificial satellites. The data thus obtained on the principal ionizing agent - short-wave solar radiation - and on the physical conditions prevailing in the upper atmosphere and in the ionosphere at different altitudes, allow the proposal of a self-consistent mechanism of ionosphere formation. A general outline of the theory of ionosphere formation at different altitudes is now complete. Its application to specific cases, dependent on a more accurate determination of input parameters to give solutions valid for a definite set of conditions etc., is yet to be accomplished. The use of artificial satellites in cosmic research yielded abundant scientific data.

Book Synopsis Ionospheric Space Weather by : Ljiljana R. Cander
Download or read book Ionospheric Space Weather written by Ljiljana R. Cander and published by Springer. This book was released on 2018-09-15 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes essential concepts of, and the status quo in, the field of ionospheric space weather. It explains why our society on planet Earth and moving outwards into space cannot work safely, function efficiently, or progress steadily without committed and comprehensive research initiatives addressing space weather. These initiatives must provide space environment specifications, warnings, and forecasts, all of which need to be timely, accurate and reliable. Cause and effect models of the Earth’s ionosphere are discussed in terms of the spatial and temporal dimensions of background variability, storms, gradients, irregularities, and waves in both current and long-term research activities. Starting from dynamic processes on the Sun, in the interplanetary medium, and in the Earth’s magnetosphere, ionosphere, and atmosphere, the text focuses on the dominant features of the plasma medium under normal and extreme conditions over the European zone during the last few Solar Cycles. One of the book’s most unique features is a series of fundamental examples that offer profound insights into ionospheric climate and weather. Various approaches for acquiring and disseminating the necessary data and forecasting analyses are discussed, and interesting analogies are observed between terrestrial and space weather – both of which could produce lasting social consequences, with not only academic but also concrete economic implications. The book’s primary goal is to foster the development of ionospheric space weather products and services that are capable of satisfying the ever-growing demand for space-based technology, and are ready for the society of the not-so-distant future.
Book Synopsis Studies on the Development of an Automated Objective Ionospheric Mapping Technique by : Wilson R. Edwards
Download or read book Studies on the Development of an Automated Objective Ionospheric Mapping Technique written by Wilson R. Edwards and published by . This book was released on 1975 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated objective analysis procedure was developed to represent the global distribution of selected ionospheric parameters on a daily basis. The analysis scheme enables the incorporation of observations or predictions of ionospheric parameters from random locations on the globle into a synoptic mapping technique that yields updated values of the parameters at specific grid points. In this report, the steps taken in the development of the analysis procedure and the accuracy of the results of global mapping of the F2 region critical frequency are described. (Author).
Book Synopsis Ionospheric Precursors of Earthquakes by : Sergey Pulinets
Download or read book Ionospheric Precursors of Earthquakes written by Sergey Pulinets and published by Springer Science & Business Media. This book was released on 2004-08-31 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aims to explain the variations of near-Earth plasma observed over seismically active areas several days/hours before strong seismic shocks. It demonstrates how seismo-ionospheric coupling is part of the global electric circuit and shows that the anomalous electric field appearing in active seismic areas is the main carrier of information from the earth into the ionosphere. The discussion of physical mechanisms is based on experimental data. The results can be regarded as the basis for future applications such as short-term earthquake prediction. It proceeds to describe existing complex systems of space-born and ground-based monitoring for electromagnetic and ionospheric precursors of earthquakes, as well as those still under construction. It is an excellent text for courses and contains a wealth of information for those scientists working in the field of natural disaster reduction.
