The Antarctic Automatic Weather Stations (AWS) network has been making meteorological observations since the early 1980s. This continent-wide network is positioned to observe significant meteorological events and increase understanding of the Antarctic surface climate, helping researchers observe and learn about the Antarctic in a warming world. Numerous studies of surface climatology in regions around the continent, such as the Ross Ice Shelf, have been possible because of the long duration of the AWS project and regular AWS maintenance. AWS-based climatology also aids in other studies, such as winter warming events.

Field Season Overview

This season, a team of two will deploy from late October to December to service the AWS stations on the Ross Ice Shelf (via Twin Otter) and in the Ross Island region (via helicopter). A second team of two will deploy from early December through early February to work on weather stations in West Antarctica via Twin Otter, as well as potentially assist O-400-M Cassano work at Siple Dome. AWS participants will also work on weather stations at Williams Field, Phoenix airfield, and Windless Bight, all accessed using land based transportation. In addition to servicing the AWS stations, the AWS team will make upgrades if time and resources allow. The team will also install a new server at McMurdo Station and work on the SDI-104 systems located at McMurdo Station. ASC Research Associate support is required throughout the year to monitor and maintain the McMurdo Station-based data systems.
