Supporting Stations: McMurdo Station, Palmer Station, South Pole Station
The Antarctic Gravity Wave Imaging Network (ANGWIN) is a cooperative effort of six international Antarctic programs to collect continent-wide gravity wave measurements. This network capitalizes on existing optical and radar measurement capabilities at McMurdo, Palmer, South Pole, and six other research stations: Halley (UK), Syowa (Japan), Davis (Australia), Rothera (UK), and Ferraz (Brazil). Infrared (IR) all-sky mesospheric OH (hydroxyl) imagers are installed at Davis, McMurdo, and Halley stations. An all-sky near-IR imager is also installed at Palmer Station to augment the existing instrumentation and create a capability for studying gravity wave properties at each site. The network quantifies the properties, variability, and momentum fluxes of short-period (less than one hour) mesospheric gravity waves and their dominant sources and effects over the Antarctic continent. Measurements at South Pole focus on quantifying the temperature signatures of gravity waves deep within the polar vortex and complementing the ANGWIN sites around the continent.
Field Season Overview
In the coming year, the Advanced Mesospheric Temperature Mapper (AMTM) at South Pole will continue to collect climatology data on the effects of gravity waves and their impact on the upper atmosphere over Antarctica. While on station this season, the team will service their computers, update acquisition software, and will provide training for the ASC research assistant on how to run and troubleshoot the instrument.
