Supporting Stations: McMurdo Station
Research Locations: AWS sites
The Antarctic Automatic Weather Station (AWS) network is the largest in the Antarctic and has the broadest spatial coverage. Its primary focus is measuring Antarctica’s surface climatology using the lengthy datasets (20 to 30 years in some cases) collected by the stations. A second focus is an investigation of the surface wind regime of the Ross Ice Shelf. In the Antarctic, short observational records and large spacing between available observations have limited the ability to observe and detect climate change. The AWS network is now capable of providing critical observational records that will allow researchers to assess the near-surface climate of the Antarctic and begin to identify signs of climate change in the Antarctic. AWS measurements also provide the verification for satellite studies and model forecasts.
Field Season Overview:
This year a field party of three will deploy to McMurdo Station to visit and repair stations on the Ross Ice Shelf, in West Antarctica and in the local McMurdo area. Three stations in West Antarctica may be removed. The continued transition of local McMurdo stations to Freewave radio modems will help reduce data telemetry costs. This project collaborates with other NSF grantees as well as other international programs. The team visits sites that report problems or cease transmitting during the austral winter. They receive support from riggers, fixed-wing and helicopter operations.
