Project Description:
The primary goal of this research is to quantify the properties, variability, and momentum fluxes of short-period (less than an hour) mesospheric gravity waves and their dominant sources and effects over Antarctica. To achieve this, researchers have implemented an ANtarctic Gravity Wave Imaging Network (ANGWIN) that provides an exceptional capability for investigating mesospheric gravity waves over selected regions around the Antarctic continent and deep in the interior, essentially creating continent-wide coverage of gravity-wave measurements. The specific research goals are: (1) Exploit one of the world's most intense gravity-wave sources, the Antarctic Peninsula, to investigate the effects of orographic forcing on mesospheric dynamics; (2) Quantify longitudinal variations in mesospheric gravity-wave activity and propagation headings around Antarctica and associated momentum flux variability; (3) Investigate the propagation and ducting of gravity waves capable of traveling large distances over the Antarctic continent; and (4) Identify dominant wave sources using combined instrument data sets together with state-of-the-art ray techniques.

Field Season Overview:
Field team members will visit the Arrival Heights facility in January 2014 to service their equipment. After that, they will travel to South Pole station to service equipment for their companion project (A-119-S). The collected data will be made available on the research team's website along with existing South Pole data.

Deploying Team Members:

  • Pierre-Dominique Pautet
  • Michael Taylor (PI)
