This book contains papers from the URSI International Symposium on Environmental and Space Electromagnetics and includes both tutorials and original presentations. The aim of the symposium was to bring together radio, atmospheric, and space scientists and engineers with different backgrounds in order to exchange information and views on new areas, thus highlighting the current state of research in radio science and interdisciplinary areas. The book covers traditional problems as well as new unconventional ones, many of which have never been discussed in an open forum before. The book covers novel topics such as spacecraft EM environments; terrestrial and extraterrestrial noise environments; planetary lightning and emissions, including the results from the Voyager-Neptune flyby; lightning and nuclear electromagnetic pulses; triggered and ball lightning; extraterrestrial noise and plasmas; seismoelectric emissions; and meteorologico-electric phenomena and EHD (electrohydrodynamics) including atmospheric EHD vortex phenomena which have drawn a worldwide public interest quite recently. More traditional subjects include man-made radio noise environment and EMC; space communication, measurement and frequency man- agement; noise and communication statistics; geomagnetic induction and radio-plasma noise; lightning; atmospherics, whistlers and emissions; and VLF/ELF EM environments. The book thus spans a wide range of radio science and will be a valuable source of new ideas, particularly in interdisciplinary areas of meteorologico-electric phenomena.
