Abstract : The polar automatic weather station (AWS) of the University of Wisconsin is a battery-powered, solar panel-charged, computer-controlled unit that measures wind speed, wind direction, air temperature, air pressure, vertical temperature difference, and relative humidity. The nominal height of the measurements is three to five meters at the time of installation. The data are transmitted to polar-orbiting satellites equipped with the ARGOS data collection system. The sensors are measured at ten-minute intervals and three to five values of each sensor are transmitted at 200-second intervals. More than 100 values at ten-minute intervals are recorded in 24 hours. Thirty-four AWS units are installed in Antarctica and four AWS units are installed on the Greenland Crest. Up to 28 of the 38 AWS units are received by the Global Telecommunications System at six-hour intervals.
