<span class="fontstyle01">world’s strongest hotspot region of stratospheric gravity wave (GW) activity. Large tropospheric winds are deflected by the Andes and the Antarctic Peninsula and excite GWs that might propagate into the upper mesosphere. Satellite
observations show large stratospheric GW activity above the mountains, the Drake Passage, and in a belt centered along 60°S. This scientifically highly interesting region for studying GW dynamics in the whole atmosphere from the troposphere to the lower thermosphere
was the focus of the Southern Hemisphere Transport, Dynamics, and Chemistry–Gravity Waves (SOUTHTRAC-GW) mission.</span></span><span style="font-size:10.0pt;font-family:"Open Sans",sans-serif;color:#424242;border:none windowtext 1.0pt;padding:0in"> The mission
took place in September 2019 during an extraordinary (and rare) Sudden Stratospheric Warming event and included the German research aircraft HALO (High Altitude and LOng Range research aircraft), which was deployed to Rio Grande at the Southern tip of Argentina.
Seven dedicated research flights with a typical length of 7000 km were conducted to collect GW observations with the novel ALIMA (Airborne LIdar for Middle Atmosphere research)-instrument and the GLORIA (Gimballed Limb Observer for Radiance Imaging of the
Atmosphere) limb sounder. While ALIMA measures temperatures in the altitude range from 20 to 90 km, GLORIA observations allow characterization of temperatures and trace gas mixing ratios below flight level (< 15 km). In addition, an instrumented glider was
deployed further north at a location called El Calafate and a considerable number of radio sondes were launched at both Rio Grande and El Calafate These observations were complemented by a suite of ground-based measurements including meteor radars, all sky
images, temperature mappers and Rayleigh lidars. The mission was conducted by a number of institutions from Germany, U.S. and Argentina.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Open Sans",sans-serif;color:#424242;border:none windowtext 1.0pt;padding:0in">We call for papers for this special issue to report results relevant for studying and understanding the atmospheric dynamics (troposphere
to lower thermosphere) during this particular time period (September-November 2019). The call is open to all theoretical, modeling, experimental and observational results independent of a direct involvement in the Southtrac campaign. Papers that are already
published or under review, which are relevant to this topic, can also be part of this special issue. If interested, author should indicate their interest by writing to the Special Section Organizers (contact information above)</span><o:p></o:p></p>
