M3-I2: GEM/CEDAR JOINT MEETING 2016 -- Santa Fe, NM
Session 1: Monday PM1 - Status, Questions, & Opportunities
Magnetospheric Effects of Ionospheric Ingection
Attendence: ~45
Summary:
It has become apparent to the magnetospheric and inner magnetospheric
modeling community that model results are dramatically altered by the
presence and placement of ionospheric ions throughout the magnetosphere.
Both quiet time and storm time ionospheric upflow and outflow must be
correctly established to advance a better understanding of the
magnetosphere-ionosphere-thermosphere (M-I-T) coupled system.
This must truly be a GEM-CEDAR joint effort to address:
the ionosphere boundary layer,
the ion energization region of the polar wind
the magnetospheric response to solar wind drivers and the ionospheric outflow
the feedback into the lower ionosphere-thermosphere
Invited speakers reviewed the status of current understanding and
modeling of the effects of ionospheric ion injections on the magnetosphere.
The GEM Focus Group Chairs presented goals-overview of plans and
moderate a discussion on new in situ observational opportunities
for metric studies on plasma sheet, ring current, and substorm dynamics
to direct improvements in the current Geospace General Circulation Models (GGCMs).

Session 2: Monday PM2 - Status, Questions, & Opportunities
Polar Wind and the Ionospheric Boundary
Attendence: ~35
Summary:
Invited speakers reviewed the status of current understanding and modeling
of ion upflow initiated in the ionospheric boundary. This is key for
proper M-I-T coupling. There are many open questions on ion energization
for the ionospheric polar wind that the community still must address.
To address this question properly, the spatial and temporal variations
of the ionospheric boundary (below 600km) must be defined accurately
in the polar and sub-auroral regions for appropriate comparison of PW model
results to satellite data.
The GEM Focus Group Chairs present goals and moderated a discussion on
the open questions of ion upflow/outflow. This effort should strive
to marshal new in situ and ground-based observational abilities with
current modeling capabilities to addressing these open issues.
CEDAR scientists are strongly encouraged to participate in this session
as a collaborative GEM-CEDAR Session on M-I-T coupling.

Attendence: ~25 and ~15
Summary:
