The Sun, Solar Analogs and the Climate : Saas-Fee Advanced Course 34, 2004. Swiss Society for Astrophysics and Astronomy
This book presents the lectures notes of the 34th Saas-Fee Advanced Course "The Sun, Solar Analogs and the Climate" given by leading scientists in the field. Emphasis is on the observed variability of the Sun and the present understanding of the variability’s origin as well as its impact on the Earth's climate. The solar variability is then studied in the broader context of solar-type stars, allowing for better understanding of the solar-activity cycle and the magnetic activity in general. This book provides an accessible and up-to-date introduction to the field for graduate students and serves as modern source of reference for active researchers in this field.
The Heliosphere through the Solar Activity Cycle
Presents the evolution of the heliosphere through an entire solar activity cycle. The last solar cycle (cycle 23) has been the best observed from both the Earth and from a fleet of spacecraft. Of these, the joint ESA-NASA Ulysses probe has provided continuous observations of the state of the heliosphere since 1990 from a unique vantage point, that of a nearly polar orbit around the Sun. Ulysses’ results affect our understanding of the heliosphere from the interior of the Sun to the interstellar medium - beyond the outer boundary of the heliosphere. Written by scientists closely associated with the Ulysses mission, the book describes and explains the many different aspects of changes in the heliosphere in response to solar activity.
Space Weather, Environment and Societies
Space Weather is the developing field within astronomy that aims at predicting the sun’s violent activity and minimizing the impacts on our daily lives. Space Weather, Environment, and Societies explains why our technological societies are so dependent on solar activity and how the Sun disturbs the transmission of information and energy. Footnotes expand specific points and the appendices facilitate a more thorough command of the physics involved. This beautifully illustrated book is written for astronomy and nature enthusiasts as well as for the undergraduate/graduate level readers who would like to better master the physics of near space.
Solar Activity and Earths Climate
This question has been a focus of scientific debate since the existence of sunspots was established in the early 17th century. Even today, however, the answer is not forthcoming; while there are valid reasons to believe that solar activity has some impact on the Earth's climate, the history of the subject shows that there have been many unsupported statements that over-estimate the effect of sunspots on climatic variations. This updated and revised edition of "Solar Activity and Earth's Climate" introduces the reader to the subject of solar activity and the connection with the Earth's climate. It focuses on how knowledge about the solar cycle and Earth's climate is obtained, and provides an in depth discussion of observations, methods and the physics involved, together with the necessary statistics and analysis
Radio Wave Propagation for Telecommunication Applications
This book describes the physical mechanisms involved in the propagation of electromagnetic waves in the radiofrequency range, inside and outside buildings, in the terrestrial and near space environments, with a special focus on mobile radio communication.
