Book excerpt: Powerful, high-frequency radio waves have been used to temporarily modify the ionosphere. Thermal and parametric interactions have led to a diverse range of observed phenomena, including generation of density striations and artificial spread-F, enhancements of electron plasma waves, production of extrathermal electron fluxes and enhanced airglow, modification of the D-region temperature and densities, wideband signal attenuation, and self-focusing and scattering of the electromagnetic waves. The physics of ionospheric modification by high-power radio waves is reviewed in the context of our current theoretical understanding; disturbance generation mechanisms are qualitatively described. In addition, results of recent experiments are summarized in which ionospheric irregularities are generated and their evolution and decay processes investigated in detail. The effects and potential controlled applications of these HF ionospheric modifications for various RF systems studies are discussed. The C3I scientific community provides an important motivation for these ionospheric modification studies; their increased interaction and active participation in experimental design and interpretation are encouraged.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the outcome of an ionospheric D-region study made with the wave interaction experimental technique mainly using the all-digitalized facilities at The Pennsylvania State University. Theoretical basis and the experimental evidence of the presence of atmospheric gravity waves in the D-region ionosphere are presented. Spectral analysis of the wave interaction data indicated that the presence of waves with periods ranging from tens of minutes to few hours are possible. Critical intercomparison of two independently-developed electron-density profile inversion techniques are presented. The results showed that the two methods led to similar profile indicating their reliability in profile inversion. Finally, temporal variations in D-region electron densities are presented showing diurnal variations as well as the variability between normal and anomalous conditions. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In 2010, NASA and the National Science Foundation asked the National Research Council to assemble a committee of experts to develop an integrated national strategy that would guide agency investments in solar and space physics for the years 2013-2022. That strategy, the result of nearly 2 years of effort by the survey committee, which worked with more than 100 scientists and engineers on eight supporting study panels, is presented in the 2013 publication, Solar and Space Physics: A Science for a Technological Society. This booklet, designed to be accessible to a broader audience of policymakers and the interested public, summarizes the content of that report.

Download or read book The Upper Atmosphere written by Walter Dieminger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1023 pages. Available in PDF, EPUB and Kindle. Book excerpt: Especially due to the increasing environmental problems there is a need to collect as many data as possible in the upper atmosphere. This book serves as a general multidisciplinary guide and introduction for a more effective use of the large amount of now available data from the Earth's atmosphere. It also shows the problems of the use of large amounts of time series data - for basic science as well as for environmental monitoring - and the related information systems. The book is aimed for scientists and students interested in the Earth's atmosphere which is vital for the understanding of environmental changes in the global system Earth.
