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.
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
