Description
This workshop is a continuation of last year’s plasmasphere boundary layer (PBL) workshop, and one of its main focuses is to addresses the goal of looking at global phenomena, in this case magnetosphere-ionosphere (MI) coupling, with a more system science approach. The PBL remains a region that is not well understood by the space science community. It is characterized by dynamic interaction between the plasmas of the ionosphere and of the inner and outer (auroral) magnetosphere. During geomagnetic storms, the ionosphere plays a critical role in the development of fast, latitudinally narrow plasma flows into the plasmapause region. The majority of space weather effects in the mid-latitudes, such as the formation of the plume of ionization associated with storm enhanced density or of the irregularities observed by the mid-latitude SuperDARN facilities, are associated with geophysical mechanisms of the PBL. Among the important interactions that occur in this region are the development of electric fields which couple the ionosphere, plasmasphere, and magnetosphere, the structuring and redistribution of thermal plasmas, and the formation of different scale-sizes of irregularities.
In this workshop we will continue to build a framework for understanding this complex region and for interpreting new observations. We also intend to explore the lesser-known processes and effects that accompany M-I coupling at the PBL. With these objectives, the workshop will begin with a few short tutorial background talks. We invite contributions and comments on the theme of M-I coupling in this region including theoretical and modeling studies and observations of phenomena associated with the PBL.
