GEM/CEDAR M3-I2 Sessions

Merged Modeling & Measurement of Ionospheric Plasma Injection into the Magnetosphere (M3I2) and Its Effects: Plasma Sheet, Ring Current, and Substorm Dynamics
M3-I2 Home - FG: Merged Modeling & Measurement of Injection Ionospheric Plasma into the Magnetosphere and Its Effects (M3-I2)			Co-Chairs: Shasha Zho, U. of Michigan/CLaSP Barbara Giles, NASA/GSFC/GPL Vince Eccles, USU/CASS	M3-I2: GEM/CEDAR JOINT MEETING 2016 -- Santa Fe, NM Session 1: Monday PM1 - Status, Questions, & Opportunities Magnetospheric Effects of Ionospheric Ingection Attendence: ~45 Summary: It has become apparent to the magnetospheric and inner magnetospheric modeling community that model results are dramatically altered by the presence and placement of ionospheric ions throughout the magnetosphere. Both quiet time and storm time ionospheric upflow and outflow must be correctly established to advance a better understanding of the magnetosphere-ionosphere-thermosphere (M-I-T) coupled system. This must truly be a GEM-CEDAR joint effort to address: the ionosphere boundary layer, the ion energization region of the polar wind the magnetospheric response to solar wind drivers and the ionospheric outflow the feedback into the lower ionosphere-thermosphere Invited speakers reviewed the status of current understanding and modeling of the effects of ionospheric ion injections on the magnetosphere. The GEM Focus Group Chairs presented goals-overview of plans and moderate a discussion on new in situ observational opportunities for metric studies on plasma sheet, ring current, and substorm dynamics to direct improvements in the current Geospace General Circulation Models (GGCMs).

This is key for proper M-I-T coupling. There are many open questions on ion energization for the ionospheric polar wind that the community still must address. To address this question properly, the spatial and temporal variations of the ionospheric boundary (below 600km) must be defined accurately in the polar and sub-auroral regions for appropriate comparison of PW model results to satellite data. The GEM Focus Group Chairs present goals and moderated a discussion on the open questions of ion upflow/outflow. This effort should strive to marshal new in situ and ground-based observational abilities with current modeling capabilities to addressing these open issues. CEDAR scientists are strongly encouraged to participate in this session as a collaborative GEM-CEDAR Session on M-I-T coupling. <a href="http://sw04.spaceweather.usu.edu/~eccles/M3I2/2016_GEMCEDAR/Ion_Outflow_Modeling_Roger_Varney_GEMCEDAR2016.pdf"> Roger Varney (SRI): Areas for Improvement in Ion Outflow Modeling</a> George Khazanov (NASA/GSFC): Polar Wind M-I-T Coupling: Kinetic vs Hydrodynamic</a> Other Contributors: Shunrong Zhang (U Mich): ISR campaign opportunities Bruce Fritz (UNH): RENU2 Sounding Rocket Douglas Rowland (NASA/GSFC): VISIONS Sounding Rocket W.
