Book Description
The importance of ionospheric irregularities in the overall concept of dynamic ionospheric physics modeling is emphasized. In particular, ionospheric irregularities produce scintillation which cause communication and radar system degradation. The determination, classification and nonlinear development of such instabilities, in terms of theoretical and numerical studies, is of fundamental importance. This report gives an overview of ionospheric irregularities and specific results in two areas: (1) nonlinear development of the type II E region equatorial electrojet instability and (2) plasma clouds, image effects and striations in the ionosphere.

Book Description
During the last week of September 1968, ESRIN (the European Space Research Institute) held the ESRIN-ESLAB Symposium on 'Low-Frequency Waves and Irregularities in the Ionosphere' in Frascati, near Rome. The symposium was attended by about 60 participants, including speakers from most of the ESRO member states, the U.S.A., the U.S.S.R., and Peru. The main topics covered were: (a) observations of ionospheric irregularities by radar scattering, (b) scintillations of satellite signals, (c) geomagnetic micropulsations, and (d) whistlers. Both theoretical and observational aspects were treated. In addition, laboratory results on low-frequency waves in plasmas were discussed, emphasis being given to their possible relevance to low-frequency ionospheric phenomena. Finally, a brief presentation (not included in these proceedings) of the ESRO rocket and satellite program was given by Dr. Pedersen of ESLAB. The symposium provided an exchange of information among workers in closely related fields. It was also valuable in bringing together people whose experience is predominantly in ionospheric observations with others whose field of interest is mainly in plasma physics (theoretical or laboratory) - a combination that seemed particularly appropriate to ESRIN's program and functions.

Book Description
The Earth's Ionosphere: Plasma Physics and Electrodynamics emphasizes the study of plasma physics and electrodynamics of the ionosphere, including many aeronomical influences. The ionosphere is somewhat of a battleground between the earth's neutral atmosphere and the sun's fully ionized atmosphere, in which the earth is embedded. One of the challenges of ionosphere research is to know enough about these two vast fields of research to make sense out of ionospheric phenomena. This book provides insights into how these competing sources of mass, momentum, and energy compete for control of the ionosphere. Some of the topics discussed include the fundamentals of ionospheric plasma dynamics; equatorial plasma instabilities; high-latitude electrodynamics; and instabilities and structure in the high-latitude ionosphere. Throughout this text only the region above 90 km are discussed, ignoring the D region entirely. This publication is a good source of information for students and individuals conducting research on earth’s ionosphere.

Book Description
A comprehensive review of global ionospheric research from the polar caps to equatorial regions It's more than a century since scientists first identified the ionosphere, the layer of the Earth’s upper atmosphere that is ionized by solar and cosmic radiation. Our understanding of this dynamic part of the near-Earth space environment has greatly advanced in recent years thanks to new observational technologies, improved numerical models, and powerful computing capabilities. Ionosphere Dynamics and Applications provides a comprehensive overview of historic developments, recent advances, and future directions in ionospheric research. Volume highlights include: Behavior of the ionosphere in different regions from the poles to the equator Distinct characteristics of the high-, mid-, and low-latitude ionosphere Observational results from ground- and space-based instruments Ionospheric impacts on radio signals and satellite operations How earthquakes and tsunamis on Earth cause disturbances in the ionosphere The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Book Description
This is the first book to review all the fields of equatorial electrojet phenomena and their relevant theories in one volume. In certain relevant sections, the book discusses both the equatorial electrojet and the world-wide parts of the Sq current systems. Onwumwchili is an internationally known and highly respected expert in the equatorial electrojet field- a brand of geomagnetism.

Book Description
Although interesting in its own right, due to the ever-increasing use of satellites for communication and navigation, weather in the ionosphere is of great concern. Every such system uses trans-ionospheric propagation of radio waves, waves which must traverse the commonly turbulent ionosphere. Understanding this turbulence and predicting it are one of the major goals of the National Space Weather program. Acquiring such a prediction capability will rest on understanding the very topics of this book, the plasma physics and electrodynamics of the system. Fully updated to reflect advances in the field in the 20 years since the first edition published Explores the buffeting of the ionosphere from above by the sun and from below by the lower atmosphere Unique text appropriate both as a reference and for coursework

Book Description
This document summarizes studies on the morphology of ionospheric structure at high latitudes. The program encompasses both theoretical and experimental investigations into this rapidly developing field. Because of the vast range of scale sizes (hundreds of kilometers to centimeters) that make up the structure, and the need for time-continuous observations, we employ a diverse set of observational techniques. These include in situ observations from rockets and satellites as well as radio propagation and scattering measurements. Topics include: F-Region Cross-Field Diffusion Processes; High-Latitude Conductivity and Field Aligned Current Systems; Low-Altitude Image Striations Associated with Bottomside Equatorial Spread F--Observations and Theory; Irregularity Decay in an Isolated Plasma Bubble; Electrical Coupling Effects on the Temporal Evolution of F-Layer Plasma Structure; Aurora and Electrojet Configuration in the Early Morning Sector; Auroral Zone Conductivities within the Field-Aligned Current Sheets, and K sub P Dependence of Auroral Zone Field-Aligned Current Intensity.
