Abstract
|
This report is a compilation of papers from academic and other research institutes that describe ionospheric phenomena and parameters that affect electromagnetic propagation. The report addresses both mid-latitude and high-latitude effects. The first chapter describes the morphology of the ionosphere, briefly covers the neutral atmosphere and expands on the influence of the geomagnetic field, ionospheric electric field and currents, and particle precipitation at high latitudes. Chapter 2 looks at the instrumentation for obtaining the relevant data. An analysis of the mapping of total electron content in geographic co-ordinates is presented in Chapter 3 with an aim of providing timely information to the users. Chapter 4 addresses spontaneous emissions observed during ground-based and rocket-borne experiments. The final chapter considers the specific effects of space weather on the ionosphere during severe geomagnetic and ionospheric storms, the impact on technology including communication and navigation systems, and emphasises the need for a global perspective of the system. Extensive references are provided for each subject. For completeness, the proceedings of a Specialists’ Meeting held in conjunction with the study are added as an appendix. | |||||||||||||||||||||||||||||||||
