2. GEM 2019 Workshop: Dipolarization and its Effects: GEM Focus Group Solicitation
------------------------------------------------------------
From: Christine Gabrielse, David Malaspina, Matina Gkioulidou, Slava Merkin, & Drew Turner (christine.gabrielse at aero.org)
**Dipolarization FG Focused Discussion: Wednesday 1:30 and 3:30 Sessions**
The GEM Dipolarization Focus Group requests participation at this year's summer GEM meeting on the topic of energy dissipation during the deceleration of dipolarizations/fast flows: what fraction of the earthward flow energy gets dissipated by which processes?
Some guiding questions to discuss:
* Can we estimate a percentage that energy is dissipated into waves, direct ion heating, etc.?
* Can we determine if and to what extent a dynamo in the transition region (driven by pressure gradients or vorticity) converts energy dissipated from the tail into field aligned currents to drive dissipation in the ionosphere?
* What are the ways to estimate these values (simulation or theory or observational)?
After receiving positive feedback for our previous mini-GEM session, we will again utilize our sessions to focus on the stated question(s) in a collaborative, workshop format. It was very productive to have participants coordinate in advance, so although this year does not present a controversy to debate, we would like participants to provide us with an informal abstract that will aid us in organizing.
**Contributed presentations: Tuesday, 3:30 Session**
We will also have one session devoted to contributed presentations that can be outside the scope of our focused question above, but should still be related to dipolarization, magnetotail dynamics, and/or its affects on the inner magnetosphere. NOTE: These cannot be full AGU style talks. We recommend to put together three slides that can be used as a discussion point. More details will be sent to contributors as GEM approaches.
Please email your title and abstract to Christine Gabrielse: christine.gabrielse at aero.org.

3. GEM 2019 Workshop: Interhemispheric Approaches to Understand M-I Coupling (IHMIC)
------------------------------------------------------------
From: Hyomin Kim, Robert Lysak, Tomoko Matsuo (hmkim at njit.edu)
We invite you to participate in our GEM focus group session, “Interhemispheric Approaches to Understand M-I Coupling (IHMIC)”. The main goal of this focus group proposal is to understand the interhemispheric symmetry/asymmetry in geomagnetic fields and its effects on M-I coupling. Observational and modeling studies have shown the interhemispheric differences which are manifested in various signatures, e.g., large-scale current systems, auroral forms, waves, ion upflow, outflow, particle precipitation, high-latitude convection and thermospheric winds.
The focus group addresses questions as to how to incorporate interhemispheric differences and their effects on M-I coupling in observations and modeling/simulations. The overarching science questions that this focus group will be addressing are:
1) In what aspect does the asymmetry in geomagnetic fields play a role in M-I coupling?
2) How are the interhemispheric differences related to solar wind and geomagnetic activities?
3) What are interhemispheric differences in storm and substorm signatures, wave activity and particle precipitation? What controls these differences?
4) How do interhemispheric differences in ionospheric conductivity affect solar wind coupling to the magnetosphere, ionosphere and thermosphere?
5) What are effects of the neutral wind dynamo in the application of Ohm's law to ionosphere-magnetosphere coupling? Does the neutral wind dynamo contribute to the interhemispheric asymmetry in M-I coupling?
The session schedules are as follows:
1) Monday (June 24) 3:30 pm – 5:00 pm
2) Tuesday (June 25) 10:30 am – 12:00 pm: Joint session with the Testing Proposed Links between Mesoscale Auroral and Polar Cap Dynamics and Substorms (MAPS) session
3) Wednesday (June 26) 10:30 am – 12:00 pm: Join session with the ULF wave Modeling, Effects, and Applications (UMEA) and Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction (DAYS) sessions.

4. GEM 2019 Workshop: Call for Participation in the new Radiation Belt FG Sessions
------------------------------------------------------------
From: Lauren Blum, Hong Zhao, Sasha Ukhorskiy, Sean Fu (lauren.w.blum at nasa.gov)
We would like to solicit participants for the new focus group “System Understanding of Radiation Belt Particle Dynamics through Multi-spacecraft and Ground-based Observations and Modeling." Four RB sessions are scheduled for the week: on Tuesday (10:30-12:30pm Introduction and discussion of open radiation belt questions; and 1:30-3:00pm Discussion and presentations on potential challenge events), Thursday (10:30-12:30pm, Joint with UMEA on EMIC waves), and Friday (10:30-12:30pm, General contributions). More details on these sessions will be available on the GEM wiki as the meeting approaches.
We are soliciting:
- potential challenge events or types of challenge events utilizing conjugate and/or multipoint measurements
- general contributions utilizing multi-point analysis, including observations and modeling
If you have any questions or would like to provide some brief slides on these topics, please contact any of the group chairs. Please include the topic of your work, to better help us sort presentations by theme. We would like to emphasize the request for discussion-based GEM sessions rather than AGU-style presentations. We look forward to your participation,
Hong (Hong.Zhao at lasp.colorado.edu)

7. JOB OPENING: Postdoctoral Position (2 Years) in Magnetospheric Physics (Space Weather) at Umeå University, Sweden
------------------------------------------------------------
From: Maria Hamrin (maria.hamrin at space.umu.se)
The aim of the project is to accomplish an advanced physical understanding of the temporal behavior of geomagnetic storms, in particular in terms of their short-term variability with respect to solar wind forcing and internal processes in the Earth's magnetosphere and magnetotail.
Magnetic storms are presently intensively studied because of their potential detrimental impact on space and ground-infrastructure in the scientific context of near-Earth space plasma processes, which today is commonly referred to as “Space Weather”. While the general temporal behaviour of a geomagnetic storm and its various long-term phases is today reasonably well understood, there are still a number of open questions about the short-term variations. While some storms (or storm-phases) exhibit smooth temporal variations, even for large amplitudes of disturbances, other storms exhibit rapid and multiple spikes (defined as periods of large dB/dt of over 1000 nT/min), which may cause the so-called “Geomagnetically Induced Currents” (GICs) discussed in Space Weather. It is not known what exactly determines the spiky nature of stormy periods as compared to other smoother periods of equally large amplitude of the total magnetic disturbances. It is therefore of relevance, both for the scientific community and for the predictability of GICs, to clarify what determines such different temporal behaviours at different times.
This is a full-time (100%) position for two years. Starting date as soon as possible or according to agreement. The postdoctoral project will be conducted in close collaboration with scientists from the University of Leicester UK, Danish Technical University Copenhagen and the Community Coordinated Modeling Center (CCMC) at NASA Goddard Space Flight Center in Washington USA. Application deadline is June 2, 2019.
