1. AGU Fall 2017 Session: Energetic Particle Precipitation: New Findings and Measurement Platforms (SM021)
------------------------------------------------------------
From: Lauren Blum, Leslie Woodger, Christopher Cully, Allison Jaynes (lauren.w.blum at nasa.gov)

Dear Colleagues,
We invite you to submit an abstract to our session on energetic particle precipitation at the upcoming Fall AGU.

SM021: Energetic Particle Precipitation: New Findings and Measurement Techniques
Session ID#: 23627

Session Description:
Precipitation into the atmosphere is an important loss process for energetic particles in Earth’s magnetosphere.   Quantification of such loss, as well as understanding of the physical mechanisms behind it through observation and simulation, is critical to our understanding of the dynamics of magnetospheres, magnetosphere-ionosphere interactions, and the chemistry and dynamics of the upper atmosphere.  Recent observations from a wide range of platforms, including balloons, ground observatories, and CubeSats, can provide important constraints on the spatial, temporal, and spectral characteristics of precipitation events.  This session welcomes submissions exploring energetic (~keV through >MeV) particle precipitation and the impact of this process on both trapped magnetospheric populations as well as atmospheric dynamics.  We especially encourage presentations utilizing different measurement types and platforms, as well as theory and modeling of the causes and effects of precipitation.

2. AGU Fall 2017 Session: Geospace Research from Polar Environments (SM025)
------------------------------------------------------------
From: Hyomin Kim, Andrew Gerrard, Alex Chartier, Michael Hartinger (hmkim at njit.edu)

Dear Colleagues,

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

SM025: Geospace Research from Polar Environments

Session ID#: 24131

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 Earth’s atmosphere, its space environment, and solar-generated interplanetary structures.  Such research includes the study of aurora, induced electrical currents, space weather, geomagnetic fields, ionospheric processes, temperature and winds in the neutral atmosphere, and atmospheric waves, all of which improve our understanding of the mechanisms which couple solar processes to the terrestrial environment.  This session solicits papers on recent advances in space physics and aeronomy focusing on the polar regions. Inter-hemispheric and conjugacy studies, as well as studies incorporating polar observations in the global context, are also welcome due to the advancement in these fields in recent years.

3. AGU Fall 2017 Session: Dayside Processes and Solar Wind-Magnetosphere Coupling (SM006)
------------------------------------------------------------
From: Sarah Vines, Heli Hietala, Brian Walsh (sarah.vines at jhuapl.edu)

Dear Colleagues,

We invite you to submit abstracts to the session "Dayside Processes and Solar Wind-Magnetosphere Coupling". This is a somewhat general dayside session to allow for abstracts covering the multitude of dayside processes (foreshock, bow shock, magnetosheath, magnetopause), as well as for abstracts dealing with solar wind-magnetosphere coupling and effects of solar wind driving on the magnetosphere.

Session Title: SM006. Dayside Processes and Solar Wind-Magnetosphere Coupling
Session ID: 23546
Session Link: https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session23546   

Session Description:
Investigating the coupling processes of plasma and energy from the solar wind to the magnetopause and into the magnetosphere provides valuable pathways for understanding our dynamic Earth system. In recent years, a significant number of spacecraft and ground-based instruments have sampled the various upstream regions and boundaries of Earth’s magnetosphere – foreshock, bow shock, magnetosheath, and magnetopause - with both in situ and remote observations. Modeling and theoretical efforts have also contributed to advance our recent understanding of the physics occurring in these regions.  This session will focus on the processing and dynamics of plasma within these dayside regions and boundary layers, and how those processes impact the solar wind-magnetosphere interaction and the generation of magnetospheric and ionospheric disturbances. Topics of interest for this session include magnetic reconnection and magnetosheath current sheets, plasma instabilities at the magnetopause and in the magnetopause boundary layers, and magnetosheath and foreshock wave-particle interactions.

4. AGU Fall 2017 Session: Dipolarization throughout the Magnetotail and its Effects on the Inner Magnetosphere (SM024)
------------------------------------------------------------
From: Christine Gabrielse, Matina Gkioulidou, David Malaspina, Drew Turner (cgabrielse at ucla.edu)

Dear Colleagues: 

We invite you to submit an abstract to the 2017 Fall AGU Session, "Dipolarization throughout the Magnetotail and its Effects on the Inner Magnetosphere".

Abstracts may be submitted here (until Aug 2): https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session26475

Session ID#: 26475
Session Description:
Dipolarization is part of a dynamic process that accelerates and transports particles throughout the magnetotail plasma sheet and inner magnetosphere, and is an important component of plasma convection in Earth’s magnetosphere. Dipolarization is also related to wave generation, which can further accelerate and/or scatter particles. This session focuses on understanding the effects of dipolarization, such as how azimuthally localized dipolarization (i.e., dipolarizing flux bundles, or plasma “bubbles”) connects to the large-scale dipolarization during substorms, how both types originate, and how small- and large-scale dipolarization impacts the inner magnetosphere.  How does outer-magnetosphere plasma sheet physics couple to inner magnetospheric dynamics, and vice versa?  This question is at a frontier of magnetospheric research and understanding the role of dipolarizations in this coupled system is key. This session solicits studies of magnetospheric dipolarization and its effects on the plasma sheet and inner-magnetosphere using in situ observations, ground-based observations, and/or models and theory.
