These proceedings are based upon the review lectures, the re- search talks and the accompanying discussion from the NATO Advanced Study Institute on "The Dynamical and Chemical Coupling of the Neutral and Ionized Atmosphere" held at Spatind, Norway April 12-22, 1977. In recent years, in spite of the many subdivisions of atmospher- ic physics it has become clear that a complete understanding of the subject matter requires an interdisciplinary effort of the scien- tists working on a variety of atmospheric phenomena. This Advanced Study Institute was organized in order to meet this demand. A...

This book is an ordered collection of tutorial lectures on the physical processes in the polar upper atmosphere given at the NATO Advanced Study Institute (ASI) on "The Exploration of the Polar Upper Atmosphere" held at Lillehammer, Norway, May 5-16, 1980. The polar cap is an important part of the high latitude atmosphere not only because of circulation and horizontal trans- port in the neutral atmosphere and convection in the ionosphere, but also because of its unique energy sources and sinks. In addition, solar wind plasma is led into-the upper atmosphere by the geomagnetic field at the...

This volume is based on lectures and discussions presented at a NATO Advanced Study Institute on ELF and VLF Radio Wave Propagation, which was held in Norway April 1974. The study of propagation of electromagnetic waves with frequen- cies below 100 kHz has long traditions in ionospheric physics. To-day, this frequency range is still of great importance, both to the physicist, who uses the waves as diagnostic tools to study the earth's environment and to the engineer who exploits the characteris- tics of these waves to improve communications, navigation and timing systems. In recent years the...

The Earth's magnetosphere is part of our environment, and physical processes in the magnetosphere and coupling between the solar energy stream, the solar wind, and the magnetosphere are important to our understanding of our environment. Variations in the electromagnetic and particle energy output of the Sun have a significant effect on global changes.

These proceedings are based upon introductory talks, research reports and discussions from the NATO Advanced Workshop on the "Morphology and Dynamics of the Polar Cusp", held at Lillehammer, Norway, 7-12 May, 1984. The upper atmosphere at high latitudes is called the "Earth's win- dow to outer space". Through various electrodynamic coupling process- es as well as through direct transfer of particles many geophysical effects displayed there are direct manifestations of phenomena occurring in the deep space. The high latitude ionosphere will also exert a feedback on the regions of the...
