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 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
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
Three tasks completed in this study are presented. (1) The climatologic model of scintillation index S4 map using the ROCSAT data during the moderate to high solar activity period is completed using the ROCSAT 32 Hz density fluctuation data collected at the 600 km altitude. The results are divided into two maps, one for strong scintillation (S4>=0.3) and the other, weak scintillation (S4

Book Description
Two major topics are studied during the first year of the two-year (2005-2007) project. The first one is the comparative study of radiowave scintillation simulations carried out with two different approaches at two different institutions: The numerical simulation with the elliptical wave equation carried out by NCU versus the numerical solution of the thin phase-screen model carried out by AFRL/VSBXI. Although AFRL/VSBXI has sent us detailed density irregularity profile at every 50 km downward from 600 km altitude where the density structure is taken from ROCSAT-1 measurement, we were unable to make good comparison with our numerical solutions at various designated altitudes because the AFRL simulated density profile does not contain the horizontal structure to have a proportional value to the measured density structure at 600 km but has a known PSD in density fluctuation with random phase. This makes comparison difficult. However, we have tuned our numerical simulation model to have an excellent agreement with the AFRL results and with single-phase or multi-phase screen results of N. Rogers from UK. Detailed comparison will be continued during the second half of the project years. The second major accomplishment is to have a detailed analysis of the statistical distribution of the midlatitude density irregularities together with case study of midlatitude irregularity characteristics and causes. The result of the case study has been written into a paper ready for submission to publish in Journal of Geophysical Research in Space Physics in July, 2006.
