<b>SESSION G13- THE HIGH-LATITUDE ATMOSPHERE:</b><o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="color:#212121">Description:<i>The use of a multi-disciplinary and multi-instruments approach, with the aid of modelling efforts, is imperative to advance the current
knowledge of the high-latitude atmosphere, including the ionosphere, and geospace. Some of the outstanding scientific questions within atmospheric and space physics, are: 1) How are different atmospheric layers coupled in the polar regions?, 2) How does the
upper polar atmosphere, i.e., mesosphere, thermosphere, and ionosphere, respond to increased geomagnetic activity, including energy transfer from space?, 3) How does the whole polar atmosphere impact short- and long-term climate variations?</i><o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><i><span style="color:#212121">Answering these questions will not only have implications on the understanding of processes in the polar atmosphere, but it will also greatly improve
our understanding of the global atmospheric dynamics. This will contribute to AGATA (Antarctic Geospace and ATmosphere reseArch), endorsed as a new SCAR (Scientific Committee on Antarctic Research) Scientific Research Programme and recognized by the ICARP
IV (Fourth International Conference on Arctic Research Planning), as a open platform of collaboration among scientists and stakeholders.</span></i><span style="color:#212121"><o:p></o:p></span></p>
<p class="MsoNormal"><i><span style="color:#212121">We welcome contributions that help to answer the outstanding scientific questions related to the whole-atmosphere coupling, space weather influences and whole atmosphere response to climate change. We also
welcome presentation and discussion of existing and planned instrumentation at high-latitudes and space-borne sensors".</span></i><span style="color:#212121"><o:p></o:p></span></p>
