1. Survey Reminder 
------------------------------------------------------------
From: Jacob Bortnik on behalf of the GEM steering committee (jbortnik at atmos.ucla.edu)

Dear GEM colleagues,

Just as a quick reminder, we ask all who attended the microaggressions plenary session at the recent GEM summer workshop to please fill out the follow-up survey and let us know what you thought (https://www.surveymonkey.com/r/YGCQLJS).  The deadline is this coming Friday July 13, 2018.

Thanks very much.

2. AGU Fall Meeting Session SM003: Geospace Research from Polar Environments
------------------------------------------------------------
From: Hyomin Kim, Andrew Gerrard, Robert Lysak, Tomoko Matsuo (hmkim at njit.edu)

Dear Colleagues,

We invite you to submit an AGU abstract the co organized (SM/AE/A/SA/SH sections) session on "Geospace Research from Polar Environments".

SM003: Geospace Research from Polar Environments

Session Description:
The uniqueness of polar regions for conducting geospace research has been acknowledged for decades.  This is because instrumentation located at high-latitudes allows access to a natural laboratory for studying the Earthâs atmosphere, its space environment, and solar-generated interplanetary structures.  Such research may include, but not limited to, the study of aurora, induced electrical currents, geomagnetic fields, ionospheric electrodynamics, ion-neutral coupling, temperature and winds in the neutral atmosphere, and atmospheric waves, all of which improve our understanding of the mechanisms which couple solar and interplanetary processes to the terrestrial environment.  This session solicits papers on recent advances in space physics, aeronomy and space weather focusing on the polar regions.  Studies discussing conjugate aspects of geospace phenomena in both hemispheres and incorporating polar observations in the global context are highly encouraged due to the advancement in these fields in recent years.

3. AGU Fall Meeting Session SM014: Plasma Dynamics in the Night-Side Transition Region
------------------------------------------------------------
From: Bea Gallardo Lacourt, Megan Gillies, Shasha Zou, Mike Henderson (beatriz.gallardo at ucalgary.ca)

Dear Colleagues, 

We invite you to submit an abstract to our AGU session focusing on the plasma dynamics in the night-side transition region. We encourage the community to submit theoretical work, in-situ measurements, and simulation studies.

Session number: SM014
Session Title: Plasma Dynamics in the night-Side Transition Region
Link to submit abstract: https://agu.confex.com/agu/fm18/prelim.cgi/Session/44653

Session description:  The night-side transition region in the Earth's magnetosphere is where the magnetic topology transitions from a stretched tail-like configuration to a more dipole-like magnetic field. This region hosts important plasma dynamics that impact the flow of energy and mass into the inner magnetosphere and it plays a critical role in the initiation and evolution of near-Earth plasma instabilities that can lead to system-wide effects. Despite its obvious importance in the coupled Magnetosphere-Ionosphere system, it remains a poorly understood region – primarily due to its time-dependent non-linear mapping to the ionosphere together with limited availability of simultaneous in-situ measurements. New observational capabilities (current and planned) are targeted at providing a wealth of information about key aspects of this region. We invite papers that aim to elucidate the dynamics of plasma processes in this region either through the use of auroral processes or constellations of detailed in-situ measurements, theory and modeling.

SM017: Quantifying Uncertainty in Space Weather Modeling and Forecasting
Dynamic solar outputs including flares, high-speed solar wind, and coronal mass ejections, drive responses in geospace that can have deleterious effects on technological systems. Further, upward propagation of atmospheric waves and tides produces natural variability in Earth's ionosphere and thermosphere. Many types of models are used to forecast, nowcast, or hindcast, space weather relevant quantities, but the uncertainty of these predictions is often not quantified or reported. Simulations of varying complexity are key to our understanding of the physics that drives space weather, and any simulation or forecast has uncertainty which can arise from a number of sources. These sources include uncertainties in the initial condition, uncertainties in input data, and approximations made in the construction of the model. The goal of this session is to showcase new research in ensemble modeling, probabilistic forecasting, model sensitivity studies, and other approaches to improve uncertainty quantification in space weather modeling and forecasting.

5. AGU Fall Meeting Session SM018: Quantitative Understanding of Particle Dynamics in Earth's Radiation Belts
------------------------------------------------------------
From: Weichao Tu, Jay Albert, Wen Li, Maria Usanova (wetu at mail.wvu.edu)

Dear Colleagues,

We invite you to submit an abstract to our session on particle dynamics in Earth’s radiation belts at the upcoming Fall AGU.

Session ID: 50432 

Session Title: SM018. Quantitative Understanding of Particle Dynamics in Earth's Radiation Belts 

Section/Focus Group: SPA-Magnetospheric Physics 

Session Link: https://agu.confex.com/agu/fm18/prelim.cgi/Session/50432

Session Description:
Understanding the build-up and decay of energetic particle fluxes in Earth's radiation belts, to the point of prediction, remains a fundamental goal of space physics. Our understanding and modeling have been greatly improved over the past few years, due in large part to observations by Van Allen Probes. It is now widely accepted that wave-particle interactions play a key role, and these effects are included in most models as quasi-linear diffusion. At the same time, the effects of nonlinear wave-particle interactions, localized nonlinear structures, large scale magnetic field irregularities, and other phenomena on particle motion remain largely unquantified. This session calls for observational, theoretical, or modeling work that quantitatively analyzes the particle dynamics in Earth's radiation belts, especially encouraging work that attempts to close the gap between these micro-physics effects on particle motion and the macroscopic behavior of the radiation belts.
