AGU Fall Meeting Session: "Geospace Research from Polar Environments" ---------------------------------------------------------------------- From: Andrew Gerrard Dear Colleagues, We would like to bring your attention to the AGU session #2420: “Geospace Research from Polar Environments.” https://agu.confex.com/agu/fm14/webprogrampreliminary/Session2420.html As a reminder, this year's AGU Fall Meeting, in San Francisco, will be held on 15 to 19 December, 2014. The abstract submission deadline is August 6, 11:59 pm EDT. 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.

AGU Fall Meeting Session: "Multi-point Observations in the Inner Magnetosphere: System-wide Understanding of Particle Transport, Energization and Loss" ---------------------------------------------------------------------- From: Matina Gkioulidou Session ID#: 2295 Session Description: Earth’s ring current and radiation belt populations dynamically evolve over different spatial and temporal scales. The ring current is a key driver of the inner magnetosphere electrodynamics, particularly during geomagnetic storms, and it also provides the necessary energy for the excitation of plasma waves that can affect the radiation belt intensities through various acceleration and loss mechanisms associated with wave-particle interactions. The goal of this session is to develop an understanding of the various multi-scale processes contributing to the global as well as the local variability of these energetic ion and electron populations, based on multi-point observations of plasma and fields both in-situ and remotely. This session is especially timely with the unprecedented opportunity for coordinated in-situ magnetospheric observations from the Van Allen Probes, GOES, THEMIS, and Cluster missions, the large ground based arrays of instrumentation (e.g. CARISMA, SuperMAG, SuperDARN), the balloon-based BARREL observatories, and CubeSat measurements.

AGU Fall Meeting Session: "Addressing Operational Space Weather Needs" ---------------------------------------------------------------------- From: Shawn Young , James McCollough , and Tim Guild (Conveners) Session ID: 3105 Description: Our understanding of space weather phenomena is growing steadily as research advances. However, the data, models, methods, and indices used to characterize the space environment can and do become obsolete or superseded. The space science research community is ideally suited to determine which of these are still adequate and how to improve them. This knowledge is critical to operators of technological systems that are sensitive to the space environment. We invite presentations on current and new ideas for forecasting methods, model development, computational optimization, incorporation of new observations, or the transition of tools to operational use. We also invite presentations with examples of extreme space environments that are reasonably likely and have defendable impacts.

AGU Fall Meeting Session: "Magnetic Reconnection and its Universal Consequences in Magnetospheric and Solar Plasmas" ---------------------------------------------------------------------- From: Pontus C. Brandt This year's Fall AGU organizes a cross-cutting session that is aimed at bringing together solar and magnetospheric researchers to foster a productive discussion on recent eye-opening results on reconnection and consequences for plasma transport and heating across the wide range of heliophysical environments. Please consider to submit your most exciting research on this topic to the session below. Session ID#: 3111 Session Title: Magnetic Reconnection and its Universal Consequences in Magnetospheric and Solar Plasmas Session Description: Magnetic reconnection occurs in a vast range of different plasma conditions, but yet may have similar critical consequences for plasma transport and heating. At Earth and Mercury, the balance between dayside and magnetotail reconnection, sets up the conditions for spontaneous reconnection in the collisionless magnetotail, leading to fast inward flows and heating. At Jupiter and Saturn, there is strong evidence for tail reconnection and similar fast inward flows, but rotational centrifugal forces are likely to be the more important driver triggering reconnection on closed field lines. At high altitudes in the solar corona, reconnection appears to take place with subsequent phenomena such as Supra-Arcade Downflows (SAD) and other instabilities with intriguing similarities to those occurring in planetary magnetotails. This session invites contributions on experimental and theoretical work that addresses reconnection and its consequence in the context of the wide range of plasma environments throughout the heliosphere.

AGU Fall Meeting Session: "Bz from the Sun to the Earth: Observations and Modeling – Reminder" ---------------------------------------------------------------------- From: Mario Bisi Dear Colleagues. We now invite you to submit contributed abstracts to our upcoming Fall AGU 2014 SH/SM/SA/NH session entitled “Bz from the Sun to the Earth: Observations and Modeling”. The session description, convenor and other relevant details are below. Details of this year’s Fall AGU can be found here:http://fallmeeting.agu.org/2014/, and the abstract-submission system is now open and can be accessed directly for this session here:https://agu.confex.com/agu/fm14/webprogrampreliminary/Session2237 .html; please note carefully that the whole submission system has changed this year (instructions/tutorial can be found here:http://fallmeeting.agu.org/2014/files/2014/06/FM14-Abstract- Submission-Instructions_FINAL-FINAL1.pdf) and that the hard submission deadline is 07 August 2014 at 03:59UT (which translates as 06 August 2014 23:59 EDT and 06 August 2014 20:59 PDT). Authors are allowed to submit up to two invited abstracts, or one invited abstract and one contributed abstract, or just one contributed abstract as first author and the first author must be a current AGU member for 2014; first authors may also submit one additional contributed abstract to an Education (ED) or Public Affairs (PA) session (please see http://fallmeeting.agu.org/2014/scientific- program/abstract-submission-policies/ for further abstract-submission rules and details). Please submit your abstract sooner rather than later in case of problems with the new submission system or with your AGU membership credentials rather than risk missing the hard deadline due to any such or other unforseen problems. Many thanks in advance and we look forward to receiving you submission shortly! Best wishes, Mario (on behalf of the session convenors as detailed below). Session Details: AGU Session ID# 2237 – “Bz from the Sun to the Earth: Observations and Modeling” – joint SH-SM-SA-NH Session Conveners: Mario M. Bisi (RAL Space, UK) – Mario.Bisi [at]stfc.ac.uk, Bernard V. Jackson (UC San Diego, USA) – bvjackson [at] ucsd.edu, J. Todd Hoeksema (Stanford University, USA) – todd [at] solar.stanford.edu, and Raymond J. Walker (UC Los Angeles/NSF, USA) – rwalker [at] igpp.ucla.edu/rwalker [at]nsf.gov. This session solicits contributions about the current status of, and potential advances in, observations, measurements, and modeling techniques used to study Bz from its origins below the solar “surface”, through the inner heliosphere to the Earth. The ability to determine and predict heliospheric magnetic field is also of high importance for space-weather forecasting; a southward-directed field component is thought to be the primary driver of sub-storms and geomagnetic activity at Earth. High-speed solar wind, especially at the time of transient structure arrival (e.g. during coronal mass ejections) at Earth, is also of a high importance in producing geomagnetic changes. Topics can include, but are not limited to, Bz emergence, Bz in the solar wind and solar-wind transients/flux ropes, tracing Bz ‘evolution’ from the Sun to the Earth, Bz predictability at the Earth, and the role Bz plays in geomagnetic activity including the flow of solar-wind energy into Earth's upper atmosphere.
