<div><b>Invitation to CEDAR Grand Challenge Workshop Session: The High-Latitude Geospace System</b></div>
<div>Wednesday June 24, 10:00-12:00, Kane 130</div>
<div><br>
</div>
<div>At polar latitudes the convergent magnetic field serves as a lens, projecting solar wind-magnetosphere-ionosphere interactions to a confined latitudinal range. The intense interplay among particles and fields within this region and along its boundaries
can drive the geospace system on a planetary scale. This Grand Challenge session seeks to gain new insight into geospace system dynamics at high magnetic latitudes through a synthesis of measurements, models, and analysis approaches, as pursued concurrently
by various groups.</div>
<div><br>
</div>
<div>This year’s session will focus on three themes: (1) Distributed sensing from ground and space, (2) Model-data assimilation, and (3) ITM measurements as magnetospheric diagnostic. The session will be guided by a series of short presentations, followed
by a group discussion about strategic investments. Audience participation/interruption is welcome!</div>
