CEDAR email: GEM-CEDAR session: The High-Latitude Geospace System (Monday 12:30-15:30, 16:00-18:00)

[Semeter, Joshua L]

Joint GEM-CEDAR breakout:<https://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:High_Latitude_Geospace_System>  “The High-Latitude Geospace System”
Monday 13:30-15:30, 16:00-18:00 (Sweeney E/F)
Conveners:  Josh Semeter (jls at bu.edu<mailto:jls at bu.edu>), Cheryl Huang (cheryl.huang at us.af.mil<mailto:cheryl.huang at us.af.mil>), Matt Zettergren (ZETTERGM at erau.edu<mailto:ZETTERGM at erau.edu>),Yanshi Huang (huangys at unm.edu<mailto:huangys at unm.edu>)

The magnetosphere, ionosphere, and thermosphere respond to variability in the solar wind as a coherently integrated system.  The most direct coupling occurs at high geomagnetic latitudes.  This session seeks to apply a system science approach to Earth’s open magnetic field regions and its dynamic boundaries.

Recent years have witnessed a rapid expansion of ground- and space-based sensors targeting the geomagnetic polar regions. These measurements are supported by an increasingly capable suite of models and assimilation strategies.  Efforts to reconcile ground- and space-based perspectives at high space-time resolution have called into question our understanding in four interrelated areas:
(1) High-latitude reconnection and plasma flows,
(2) mass transport and ion outflow,
(3) ionospheric variability and energy dissipation,
(4) ionospheric destabilization and turbulence.

This grand-challenge workshop provides a forum for investigators interested in the physics of Earth’s geomagnetic polar regions.  The session format will consist of clusters of short presentations interspersed with open discussion.   Please email the conveners if you have a brief topic or result you’d like to share.   Current discussion leaders (tentative):

Session 1:
Joshua Semeter (session overview, PMAFs and small-scale convection cells)
Toshi Nishimura  (polar cap precipitation and interpretation)
Seebany Datta-Barua  (Lagrangian coherent structures)
Robert Gillies (RISR-C / PolarDARN / SWARM / Imager comparisons)
Roger Varney  (topside experiments with RISR-N and RISR-C)
Hassan Akbari  (Ionospheric destabilization: drivers and consequences)

Session 2:
Ildiko Horvath (stormtime flows, presented by Cheryl Huang)
Yanshi Huang (DMSP-ESR conjugate studies of plasma state)
Ryan Mcgranaghan  (ionospheric variability and AIMIE-2)
Matthew Zettergren (Mesoscale density structures and grad-drift instability)
Ying Zou (SWARM observations of polar FACs)
Manbharat Singh Dhadly (ion-neutral interactions and climatology)

Please monitor the session web page<https://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:High_Latitude_Geospace_System> for changes.   We understand there are many concurrent sessions throughout the meeting, and we hope to see at least 1/9 of you at our sessions on Monday (Note: Session hopping is encouraged!)
