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. 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. 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.
Field Season Overview
A new all-sky near-IR imager was installed at Palmer station in May 2016. Researchers do not plan to deploy to Palmer Station this season. An ASC research associate will perform routine monitoring and maintenance on the instrument, and will download acquired image data and send it to the home institution for further analysis.
