Book Description
International Series of Monographs on Electromagnetic Waves: Ionospheric Sporadic E focuses on the methodologies, approaches, reactions, and calculations involved in the study of the ionospheric sporadic E. The selection first offers information on the occurrence of sporadic E and reflection mechanisms for sporadic E, as well as geographic occurrence and temporal variations of sporadic E and thin and scattering models. The text then examines the final remarks of the 1957 AGARD conference of sporadic-E ionization and study of radio wave scattering from sporadic E near the magnetic equator. The publication takes a look at sporadic E as observed with rockets and backscatter observations of sporadic E. Discussions focus on gradients, height preference, gradients in electron density, time variation, and interpretation and observation limitations. The text then ponders on lunar tidal variations of sporadic E and theoretical study of sporadic-E structure in the light of radio measurements. The selection is a vital reference for readers interested in the in the study of the ionospheric sporadic E.

Book Description
This book is a multi-author treatise on the most outstanding research problems in the field of the aeronomy of the Earth’s atmosphere and ionosphere, encompassing the science covered by Division II of the International Association of Geomagnetism and Aeronomy (IAGA). It contains several review articles and detailed papers by leading scientists in the field. The book is organized in five parts: 1) Mesosphere-Lower Thermosphere Dynamics and Chemistry; 2) Vertical Coupling by Upward Propagating Waves; 3) Ionospheric Electrodynamics and Structuring; 4) Thermosphere- Ionosphere Coupling, Dynamics and Trends and 5) Ionosphere-Thermosphere Disturbances and Modeling. The book consolidates the progress achieved in the field in recent years and it serves as a useful reference for graduate students as well as experienced researchers.

Book Description
This introductory text replaces two earlier publications (Davies 1965, 1969). Among the topics: characteristics of waves and plasma, the solar-terrestrial system, the Appleton formula, radio soundings of the ionosphere, morphology of the ionosphere, oblique propagation, importance of amplitude and phase, earth-space propagation.

Book Description
Previous research results on high latitude sporadic E are surveyed, and replotted and displayed in Corrected Geomagnetic Latitude (CGL) AND Corrected Geomagnetic Time (CGT) and related to current research results. Patterns of occurrence of sporadic E are developed, showing percent of time of occurrence in location in the CGL/CGT coordinate system, in terms of sporadic E top frequency (fE sub s) and magnetic activity level. Patterns of E sub s occurrence are related to concepts of the auroral oval, polar cap, and substorms. Sporadic E with top frequency = or> MHz is related to substorms. This sporadic E occurs in the late evening-early night sector of the CGL/CGT coordinate system. Implications of sporadic E on high latitude HF propagation during solar cycle maximum and minimum are discussed. (Author).

Book Description
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.

Book Description
Reports of the occurrence of ionospheric sporadic E clouds from radio amateurs operating on a frequency near fifty megahertz are analyzed on a synoptic scale and compared with the occurrence of thunderstorms and of jet streams. A mechanism is suggested for the observed interrelation between Es and thunderstorms. No definite conclusion is drawn concerning the possible relationship between Es and jet streams. (Author).
