Summary: This climatological study makes use of the temperature, wind, and precipitation records from 12 stations on the Greenland Ice Sheet. Many of these stations were not in operation for concurrent periods and records for a year or more were available from only a few of them. The mean, mean maximum, mean minimum, absolute maximum, and absolute minimum temperatures were computed from the records. The highest absolute maximum temperature reported was 44°F at Mint Julep in southwestern Greenland. The lowest absolute minimum was -94°F at Northice in northern Greenland. This study shows that the prevailing wind usually was from the direction of the high central area of the ice sheet. Stations on the west slope had prevailing winds with an easterly component whereas stations on the east slope had prevailing winds with a westerly component. The wind speed varied from 0 to approximately 60 kt, but was predominantly in the 0 to 20 kt range. At some of the stations on the ice sheet, precipitation was measured in precipitation gages, at others it was measured as surface accumulation. At many locations the annual accumulation was determined from stratigraphic studies of the snow profile. The number of days on which snow occurred, expressed as percent of total days of observation, was used as an index to the amount of snowfall. The mean annual accumulation shows precipitation to be heavier on the west slope of the ice sheet than in other areas. The precipitation records at Northice indicate that the annual precipitation in that part of northern Greenland may be very light. The means for the various climatological parameters covered in this study are presented in tables and on a climatological map which presents a cartographic picture of the overall climatology of the Greenland Ice Sheet.
