Magnetospheric physics addresses a vast array of topics, including the interaction of the solar wind with the magnetosphere, how the magnetosphere interacts with the ionosphere, and a host of processes that occur within the dayside magnetosphere.

The AGU Chapman Conference on Dayside Magnetosphere Interactions held in July 2017 in Chengdu, China, addressed the processes by which solar wind mass, momentum, and energy enter the magnetosphere. Topics discussed included the foreshock, bow shock, magnetosheath, magnetopause, and cusps; the dayside magnetosphere; and both the dayside polar and equatorial ionosphere. The meeting was particularly timely due to the results expected from NASA’s magnetospheric multiscale (MMS) mission that was launched in March 2015, arrays of new ground‐based instrumentation being installed, as well as the ongoing operations of NASA’s Time History of Events and Macroscale Interactions during Substorms (THEMIS) and Van Allen Probes missions, European Space Agency (ESA)’s Cluster mission, and Japan Aerospace Exploration Agency (JAXA)’s Geotail mission. Parallel processes occur at other planets, and recent results from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission to Mars, as well as ESA’s Mars and Venus Express missions were also discussed.

The 2017 Chapman Conference built upon two previous Chapman Conferences on the dayside boundary of the magnetosphere and their related publications: Earth’s Low‐Latitude Boundary Layer (Geophysical Monograph 133, 2003) and Physics of the Magnetopause (Geophysical Monograph 90, 1995).

These two Chapman Conferences on dayside dynamics were held more than one or two solar cycles ago. Thus, a Chapman Conference on dayside interactions was very much overdue given the new data sets brought by the constellation missions launched since then.

This monograph includes papers presented at the 2017 Chapman Conference as well as invited papers from experts who did not attend. It starts with a brief history of dayside magnetospheric physics and transients (Otto, Chapter 1). Part I considers the physics of dayside magnetospheric response to solar wind discontinuities. This section presents a summary by the Geospace Environment Modeling (GEM) Focus Group of findings on transient phenomena at the magnetopause and bow shock, and their geoeffects (Zhang and Zong, Chapter 2), solar wind–magnetosphere–ionosphere interactions driven by foreshock transients, magnetosheath high‐speed jets, and localized magnetopause reconnection (Nishimura et al., Chapter 3), and solar wind dynamic pressure changes (Shi et al., Chapter 5). Throat aurora that might be driven by magnetosheath high‐speed jets is also discussed (Han, Chapter 4). Part II is devoted to the structure and dynamics of dayside boundaries. This section includes Cluster mission’s recent highlights at dayside boundaries (Escoubet et al., Chapter 6), the structure and dynamics of the magnetopause and the magnetosheath (Nykyri, Chapter 7; Němeček et al., Chapter 8), and a review of different methods to find magnetic nulls and reconstruct magnetic field topology (Fu et al., Chapter 9). Part III examines the roles of solar wind sources on wave generations and dynamic processes in the inner magnetosphere. This includes a theoretic study on the spatial structure of toroidal standing Alfvén waves in the magnetosphere (Leonovich and Kozlov, Chapter 10), wave–particle interactions in Earth’s outer radiation belt (Rankin et al., Chapter 11; Li et al., Chapter 12), and a review of the current status of radiation belt and ring current modeling (Fok, Chapter 13). Part IV addresses cold plasmas of the ionospheric origin including the geospace plume (Foster, Chapter 14), ionospheric patches (Zhang et al., Chapter 16), and their interaction with ULF waves in the magnetosphere (Zong et al., Chapters 15 and 17).

Over 128 scientists from more than 20 countries participated in the conference. We acknowledge help from AGU staff for the success of the conference as well as the completion of this monograph. Also we acknowledge financial support from National Science Foundation and Peking University.
