Automatic Weather Stations


Scientists in the Automatic Weather Station (AWS) project at SSEC design, assemble, install, and maintain automated weather station units in remote areas of Antarctica to support meteorological research and forecasting. At any one time, approximately 55 University of Wisconsin AWS units are operating across the Antarctic continent.

Each AWS unit measures air temperature, wind speed, wind direction, and air pressure. Some measure humidity, temperature differences from the top to the bottom of the AWS Tower, snow temperatures, and even water temperature. Each unit records data in roughly ten-minute increments and transmits this data via satellite to SSEC, as well as to McMurdo Station, Antarctica. This data is then used by forecasters in Antarctica as well as by researchers around the world.
