The field of solar physics and solar--terrestrial relation, now called space weather, is evolving rapidly. As in the first edition, it is assumed that it is inevitable for the reader to get some basic knowledge in solar physics since the Sun is the main driver for space weather The term space weather itself has been gaining more and more attention during the past years as our society becomes more and more dependent on satellites, which are vulnerable to varying conditions in space. Space weather efforts and investigations are being made all over the world and more and more is known about the complex relations of processes on the Sun and the Earth and its space environment. The term space climate nowadays includes the long-term variations caused mainly by the Sun on the Earth and the interplanetary space. As in the first edition of the book, this edition also covers these topics but new chapters have been introduced, e. g. , a chapter on real-time space weather forecasts and some main space weather data sources. All the chapters have updated information, taking into account the results of new satellite missions and telescopes. The book also includes a great amount of new literature (more than 340 original citations) so that the reader is able to go into more details, if required in the respective chapters.
This second edition is a great enhancement of literature which will help the reader get deeper into the specific topics. There are new sections included such as space weather data sources and examples, new satellite missions, and the latest results. At the end a comprehensive index is given which will allow the reader to quickly find his topics of interest.
The Sun and Space weather are two rapidly evolving topics. The importance of the Sun for the Earth, life on Earth, climate and weather processes was recognized long ago by the ancients. Now, for the first time there is a continuous surveillance of solar activity at nearly all wavelengths. These data can be used to improve our understanding of the complex Sun-Earth interaction.
The first chapters of the book deal with the Sun as a star and its activity phenomena as well as its activity cycle in order to understand the complex physics of the Sun-Earth system. The reader will see that there are many phenomena but still no definite explanations and models exist for many of them. Other topics are the influences on the Earth's atmosphere, long and short term climate variations. The last chapters discuss the protection against enhanced radiation environment in view of upcoming manned missions to the Moon and Mars, and the threat from space debris, asteroids and meteoroids.
Since the field is quite interdisciplinary, the book will be of interest to scientists working in different fields such as solar physics, geophysics, and space physics.
