Geospace Research from Polar Environments

Session ID#: 80336

Session Description:
The uniqueness of polar regions for conducting geospace research has been acknowledged for decades.  This is because instrumentation located at high-latitudes allows access to a natural laboratory for studying the Earth’s atmosphere, its space environment, and solar-generated interplanetary structures.  Such research may include, but not limited to, the study of aurora, induced electrical currents, geomagnetic fields, ionospheric electrodynamics, ion-neutral coupling, temperature and winds in the neutral atmosphere, and atmospheric waves, all of which improve our understanding of the mechanisms which couple solar and interplanetary processes to the terrestrial environment.  This session solicits papers on recent advances in space physics, aeronomy and space weather focusing on the polar regions.  Studies discussing conjugate aspects of geospace phenomena in both hemispheres and incorporating polar observations in the global context are highly encouraged due to the advancement in these fields in recent years.
