		+
		+	The goal of the Storm-Time Inner Magnetosphere-Ionosphere Convection (SIMIC) Focus Group is to use ground- and space-based observations in conjunction with numerical simulation results to synthesize a new understanding of how plasma distributions, convection electric fields, and current systems emerge and evolve in the inner magnetosphere and conjugate ionosphere during geomagnetic storms.
		+
		+	At the 2017 GEM Summer Workshop, we will hold our last session on Wednesday 3:30-5:00 pm. We solicit contributions to follow up on previous topics, particularly on the SAPS challenge, but also more broadly anything relevant to the group. Since this is the last session, we will also discuss our achievements, and would welcome any contributions on open/unsolved problem that remain.
		+
		+	Particular topics of interest include: spatiotemporal dynamics of the Sub-Auroral Polarization Stream (SAPS), shielding by region-2 currents, active ionosphere-thermosphere feedback, and plasmasphere depletion/refilling. If you have data or simulation results relevant to either or both of these events -- please bring it!
		+
		+	We are looking for short workshop-style talks (i.e. a few slides only!) which are forward-thinking, focused on asking questions (rather than answering them), and searching out new opportunities to collaborate. If you would like to show a few slides in the SIMIC session please email Mark Engebretson (engebret at augsburg.edu) Peter Chi (pchi at igpp.ucla.edu) and with a short description of what you would like to present.

 Here's to a great SIMIC kick-off!
 == Abstract ==
 A new GEM Focus Group (FG) is proposed to study Storm-Time Inner Magnetosphere – Ionosphere Convection (SIMIC). This FG will bring together experimentalists, modelers, and theorists to synthesize a new understanding of how plasma distributions, convection electric fields, and current systems emerge and evolve in the inner magnetosphere and conjugate ionosphere during geomagnetic storms. The new SIMIC FG is motivated by: (1) improvements in self-consistent physics-based modeling of the coupled inner magnetosphere-ionosphere system which require ongoing validation and improvement, (2) several recent augmentations to ground- and space-based instrumentation which collectively provide new datasets with unprecedented spatiotemporal coverage and resolution, and, (3) recent ramping up of solar activity leading to increased geomagnetic activity. Two specific scientific themes related to inner magnetosphere - ionosphere convection that will be explored in detail are the Sub-Auroral Polarization Stream (SAPS) and penetration electric fields. The new SIMIC FG will build upon the achievements of two existing FGs which are just now coming to completion in 2012-2013, namely, the Near-Earth Magnetosphere: Plasma, Fields and Coupling FG and the Plasmasphere-Magnetosphere Interactions FG. The new SIMIC FG will also be complementary to several ongoing FGs, such as Scientific Magnetic Mapping and Techniques (SMMT) and Tail-Inner Magnetosphere Interactions (TIMI). The specific goals of the SIMIC FG are: (1) develop an improved canonical description of convection in the coupled inner magnetosphere - ionosphere during storms, (2) validate and improve the performance of coupled inner magnetosphere-ionosphere models, and, (3) make steps toward developing a new module for active ionospheric feedback during storms. A particular emphasis of the SIMIC FG will be to encourage the use of spatially distributed ionospheric measurements and network magnetic observations for validating and improving geospace models. Finally, there will be ample opportunity to involve the CEDAR community which has similar interests in examining geomagnetic storm phenomena and has several useful datasets that can be brought to bear on this problem.
-== Topic Description ==
+==== Topic Description ====
 To be able to understand and model the dynamics of the Geospace environment, the GEM community has always sought to analyze how large-scale magnetospheric current systems and plasma flows are generated, and how mass, energy, and momentum flow throughout the coupled magnetosphere-ionosphere-thermosphere system. The large-scale global electric and magnetic fields play a major role in magnetospheric convection. For example, it is now known that plasma convection in the inner magnetosphere - ionosphere: (1) can be highly structured by forming subauroral polarization stream (SAPS) channels, (2) may be transient at times (i.e. prompt penetration ionospheric electric fields), (3) is important for controlling plasmasphere dynamics, and, (4) includes magnetospheric dipolarization fronts associated with entropy “bubbles” and auroral phenomena that have meso-scale transient convection signatures. Yet our understanding of these dynamical processes in the inner magnetosphere during active periods is quite limited due to the paucity of spacecraft measurements in the region of interest. As a result, existing empirical models of the inner magnetosphere are static and statistical in nature, with most of them being based on single-point spacecraft measurements accumulated over extended periods of time. Therefore, further progress in geospace modeling requires an improved understanding of the coupling of convection features between the inner magnetosphere and ionosphere during geomagnetic storms. The new SIMIC FG will bring together globally distributed space- and ground-based datasets to characterize storm-related convection dynamical processes in the inner magnetosphere-ionosphere region, and fully coupled magnetosphere-ionosphere models to examine large-scale features of inner magnetosphere-ionosphere coupling during geomagnetic storms (e.g. SAPS, penetration electric fields, and substorm-related signatures). The assembled data sets will also be used to assess the accuracy of the modeling results.
