H11: Plasma interactions with solar system bodies (3), Remote sensing of the Plasmasphere (1)

Friday, August 22  13:40-15:40,  Room #11

Session Chairs: Anders Jorgensen, Christian Mazelle, Yoshiya Kasahara

First 2 talks: Plasma interactions with solar system bodies drastically change depending on the environment of the bodies such as presence of intrinsic magnetic field, atmosphere, and solid surface. For instance, the solar wind plasma directly impacts on the exosphere, atmosphere or surface of non-magnetized bodies such as Mars, Venus and moon and plasma wake is created in the nightside tail region, while magnetized planets are protected by their intrinsic magnetic fields and the solar wind-magnetosphere coupling plays an important role in plasma dynamics. As signatures of the interaction, various kinds of radio emissions and plasma waves are generated in numerous regions of our solar system. The aim of this session is to present recent progress in spacecraft observations, computer simulations and theoretical studies on plasma physics related to the solar wind and plasma flow interaction with solar system bodies. Papers related to future missions and research projects are also welcome. 4 talks: 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.
