Book Description
A computer program which calculates electron and ion densities, ionospheric conductivities, electric fields and currents, and magnetic variations in regions near the magnetic equator is described in detail. It is also explained how this numerical model can be used to deduce F-region vertical plasma drifts in the equatorial ionosphere from observed magnetic variations at ground level. (Author).

Book Description
The equatorial electrojet (EEJ) is an intense electric current that flows in the ionosphere in a narrow zone above the magnetic dip equator during the daytime. The electrojet current produces a large enhancement of the surface component of the geomagnetic field at and in the vicinity of the dip equator. The EEJ is most intense around local noontime and appears to be more stable than other ionospheric current systems. This report presents a brief overview of the characteristics of the EEJ, including its location, electron density profile, current distribution, and magnetic field. In addition, the diurnal and seasonal variations of the EEJ are discussed. The relationship of the EEJ to the worldwide dynamo current system is discussed, in addition to a comparison with the aurora electrojet (AEJ). A derivation of the EEJ current distribution is presented that is based on an anisotropic conductivity model of the ionosphere. A summary of several experiments involving the generation of low4requency signals from a heated and modulated EEJ is also given. It is anticipated that this report will provide helpful background information to scientists and engineers engaged in the development of future experiments that involve the transmission of signals in the ELF and VLF frequency bands from a heated and modulated EEJ.

Book Description
The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics, from the salient physics and its mathematical representation to practical implementation in the field, data processing, modeling and geological interpretation. Electromagnetic induction in 1-D, 2-D and 3-D media is explored, building from first principles, and with thorough coverage of the practical techniques of time series processing, distortion, numerical modeling and inversion. The fundamental principles are illustrated with a series of case histories describing geological applications. Technical issues, instrumentation and field practices are described for both land and marine surveys. This book provides a rigorous introduction to magnetotellurics for academic researchers and advanced students, and will be of interest to industrial practitioners and geoscientists wanting to incorporate rock conductivity into their interpretations.

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.
