SPATIAL AND TIME DISTRIBUTION OF LIGHTNING WHISTLERS IN THE PLASMASPHERE OBSERVED BY VLF/WBA ONBOARD AKEBONO| Session Chair: | János Lichtenberger |
The dynamics of the plasmasphere play an important role in Earth’s space weather system, and are governed by solar activity. The plasmasphere is permanently influenced by the regions below (ionosphere) and above (outer magnetosphere). The plasmasphere forms the cold plasma background for the overlapping ‘warm’ (ring current) and ‘hot’ (radiation belts) regions and its plasma distribution is a fundamental parameter for the description and modelling of the acceleration, decay and transport of radiation belt particles. The dynamics of the plasmasphere require monitoring, modeling and forecasting. This session focuses on various remote-sensing techniques (active and passive ground-based measurements using ULF-ELF-VLF electromagnetic waves as well as satellite-based methods; in-situ density measurements, radio sounding and imaging) and integration of the data obtained by them into various (physics based and data driven) plasmasphere models.
