Description

The Antarctic Gravity Wave Imaging Network (ANGWIN) is a cooperative effort between six international Antarctic programs to collect continent-wide gravity wave measurements. This network capitalizes on existing optical and radar measurement capabilities at McMurdo, South Pole, and six other research stations: Halley (UK), Syowa (Japan), Davis (Australia), Rothera (UK), and Ferraz (Brazil). Infrared, all-sky, mesospheric hydroxyl imagers are installed at Davis, McMurdo, and Halley stations. The network quantifies the properties, variability, and momentum fluxes of short-period 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 on complementing the ANGWIN sites around the continent.


Field Season Overview

The instruments for this project, an all-sky airglow imager and an advanced mesospheric temperature mapper (AMTM), are located on the B2 mezzanine at South Pole Station. They run continuously during the dark periods of winter, essentially autonomously, with only limited intervention required by an onsite research associate and by the science party via the internet. One participant will deploy from mid-January until early February to service instruments at both South Pole and McMurdo stations.
