CEDAR email: 2014 AGU session: The Dynamic Polar Cap.

[Yanshi Huang]

Dear Colleagues,

We would like to invite you to participate in the 2014 AGU session: The Dynamic Polar Cap.
The deadline for submitting an abstract is August 6, 2014 (Wednesday).

Thanks.

Session Title: The Dynamic Polar Cap
Session ID#: 2082

Session Description: The polar cap is often overlooked in studies of high-latitude ionosphere-thermosphere (IT) dynamics
in which the auroral zones on closed field lines form the primary focus.   However, there is a growing body of evidence which
may revise that paradigm by placing the cusp and polar cap at the center of energy transfer to the IT system.   Examples
include direct observations of anomalously high neutral densities, electromagnetic energy input, evidence of in situ Joule
heating in the polar cap, storm-enhanced densities, polar cap patches and ion outflows.   This session solicits presentations
on these and other polar cap phenomena with the overall goal of forming a unified framework of high-latitude dynamics in
which the relative roles of the polar cap and auroral zones are assessed.    We encourage submission of papers reporting
data analysis, modeling and theory of the polar cap and adjoining auroral zones.
