The Space Physics and Aeronomy collection is a five-volume set of books presenting the latest scientific observations, models, and theories. Arranged sequentially, the books examine the Sun and the solar wind, magnetospheres in the Solar system, Earth's ionosphere, Earth's upper atmosphere, and the effects of space weather. Volume 1: Solar Physics and Solar Wind -- A comprehensive view of our Sun at the start of a new era in solar and heliospheric physics Volume 2: Magnetospheres in the Solar System -- An overview of current knowledge and future research directions in magnetospheric physics Volume 3: Ionosphere Dynamics and Applications -- A comprehensive review of global ionospheric research from the polar caps to equatorial regions Volume 4: Upper Atmosphere Dynamics and Energetics -- A comprehensive overview of the structure and variability of the upper atmosphere Volume 5: Space Weather Effects and Applications -- Examines how solar and terrestrial space phenomena affect sophisticated technological systems The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
