Physical Processes at the Surface of the Arctic Tundra

Abstract

The results of measurements of net total radiation flux and temperatures in the air and surface layers of the tundra and snow near Barrow, Alaska, are presented for the period September 1965 to September 1966. Lowest average monthly temperatures occurred in March, the highest in July. The minimum average net total radiation occurred in January with the maximum in July. The tundra surface began to thaw by 18 June and to freeze by September.
