Available in PDF, EPUB and Kindle. Book excerpt: A critical study of the interrelationship between ionospheric environmental characteristics and HF radio propagation phenomena using satellites is described. The project is implemented by the experiment consisting of two slowly-separating satellites in the lower F-region ionosphere and two special receiving-transmitting ground stations. Measurements of radio propagation characteristics are made along the signal path between satellites as well as to the ground until separation reaches antipodability. These measurements including signal loss, pulse dispersion, long-range ducting, radio holes and shielding from ground, space, or other satellites to be compared with calculations based on simultaneous environmental measurements are discussed. Environmental data to be measured includes in-situ electron densities, integrated values along signal paths near ground stations using dispersive doppler, Faraday, and pulse-delay techniques. Top and bottom sounder data will be combined with the propagation data using sophisticated 3-D ray-tracing techniques. The result is a comprehensive synoptic picture of the complex ionosphere-structure propagation-effect to provide new insights into ducting, especially the separation of various phenomena such as injection-ejection, scatter effects, antenna detuning and plasma resonances, and the role of irregularities. Predicted propagation results, including ray patterns, calculated for expected ionospheric conditions at the time of the anticipated experiment are presented together with a description of the instrumentation.

This book was released on 2015-09-21 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.

This book was released on 2021-04-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines how solar and terrestrial space phenomena affect sophisticated technological systems Contemporary society relies on sophisticated technologies to manage electricity distribution, communication networks, transportation safety, and myriad other systems. The successful design and operation of both ground-based and space-based systems must consider solar and terrestrial space phenomena and processes. Space Weather Effects and Applications describes the effects of space weather on various present-day technologies and explores how improved instrumentation to measure Earth's space environment can be used to more accurately forecast changes and disruptions. Volume highlights include: Damage and disruption to orbiting satellite equipment by solar particles and cosmic rays Effects of space radiation on aircraft at high altitudes and latitudes Response of radio and radar-based systems to solar bursts Disturbances to the propagation of radio waves caused by space weather How geomagnetic field changes impact ground-based systems such as pipelines Impacts of human exposure to the space radiation environment 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.
