Dawn–dusk asymmetries are ubiquitous features of the plasma environment of many of the planets in our solar system. They occur when a particular process or feature is more pronounced at one side of a planet than the other. For example, recent observations indicate that Earth′s magnetopause is thicker at dawn than at dusk. Likewise, auroral breakups at Earth are more likely to occur in the pre–midnight than post–midnight sectors.

Increasing availability of remotely sensed and in situ measurements of planetary ionospheres, magnetospheres, and their interfaces to the solar wind have revealed significant and persistent dawn–dusk asymmetries. As yet, there is no consensus regarding the source of many of these asymmetries, nor the physical mechanisms by which they are produced and maintained.

Volume highlights include:

  • A comprehensive overview of mechanisms and current knowledge about dawn–dusk asymmetries in the plasma environments of planets in our solar system
  • Valuable contributions from internationally recognized experts, covering observations, simulations and theories on all important aspects of dawn–dusk asymmetries
  • Discussions of space weather effects caused by dawn–dusk asymmetries

Dawn–Dusk Asymmetries in Planetary Plasma Environments is a valuable resource for academic researchers in space physics, planetary science, astrophysics, physics, geophysics, and earth science.
