The study is based on available temperature, wind, and precipitation records for 12 stations on the Greenland Ice Sheet for varying periods dating back to 1930. The means of the climatological parameters studied are tabulated, including mean and extreme temperatures for the period of record at each station, the frequency distribution of wind speed and direction, and the precipitation, accumulation, and number of days with snowfall. A climatological map is included which presents a cartographic picture of the over-all climatology of the Ice Sheet. (Author).
