Gravity waves are key drivers of the general circulation and temperature distributions throughout the middle and upper atmosphere. 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). 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-infrared (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 team of two will deploy to McMurdo Station to service the all-sky imager and the Advanced Mesospheric Temperature Mapper (AMTM) currently installed at Arrival Heights. They will then fly to the South Pole for about four days to check the large IR imaging system, clean the optics, and train the new support contractor research associate. No team members will deploy to Palmer Station this season. Image data obtained during the winter season at Palmer Station will be sent to the home institution for analysis.
