Description
Since the pioneering observation of Shelley et al. shortly before the first Yosemite space physics meeting, observations from several satellites and from sounding rockets and ground-based radar have contributed to shape our present view of ionospheric ion outflows and their central role in magnetosphere-ionosphere-thermosphere coupling. This view comprises of two categories of outflow populations: thermal outflows, including the polar wind and auroral bulk ion up-flow, and suprathermal ion outflows, including ion beams, ion conics, transversely accelerated ions and upwelling ions – with the former constituting an important source of low-energy plasma for the latter at higher altitudes. Both ion outflow categories are strongly influenced by the solar EUV irradiance and solar wind energy input and the state of the magnetosphere-ionosphere-thermosphere. In this talk, we will focus on the interconnection between different outflow populations and the gaps in our current knowledge on this interconnection.
