<div>At high latitudes, the convergent magnetic field serves as a lens, projecting interactions among the solar wind, magnetosphere, ionosphere, and thermosphere to a limited latitudinal range which can, in turn, drive geospace dynamics at all latitudes.
This Grand Challenge workshop seeks to exploit the growing network of sensors deployed to the polar regions to improve our understanding geospace in Earth's open magnetic-field regions. Our arsenal of sensors now includes the first ever incoherent scatter
radars deployed to the north geomagnetic pole (RISR-N and RISR-C) and two new satellite missions (e-POP and SWARM), which are providing new constraints above and within the high-latitude ITM system. </div>
<div><br>
This 4-year workshop will provide a forum for investigators looking into different aspects of the same physical system. The goals for the first year are to assess the state of knowledge, identify controversies, and plan experimental operations. The science
questions that will guide our inaugural session are:</div>
<div><span class="Apple-tab-span" style="white-space: pre;"></span>• How does solar wind-magnetotail-ionosphere coupling affect the structure and composition of the polar ionosphere?<br>
<span class="Apple-tab-span" style="white-space: pre;"></span>• What are the effects on the neutral atmosphere, and what is the range of influence of these disturbances?<br>
<span class="Apple-tab-span" style="white-space: pre;"></span>• What governs the internal structure and RF propagation characteristics of plasma patches?<br>
<span class="Apple-tab-span" style="white-space: pre;"></span>• How do these processes affect plasma outflow and its impact on magnetospheric configuration?<br>
<br>
