SUMMERTIME RADIATION BALANCE AND ENERGY BUDGET OF THE CANADIAN TUNDRA.

As a step toward understanding the interrelationships between landform, vegetation, and climate of the Canadian tundra, summertime radiation balance and energy budget data obtained during July and August, 1966, at three locations in the district of Keewatin, N.W.T., are presented. Comparisons are ma...

Description
Summary:As a step toward understanding the interrelationships between landform, vegetation, and climate of the Canadian tundra, summertime radiation balance and energy budget data obtained during July and August, 1966, at three locations in the district of Keewatin, N.W.T., are presented. Comparisons are made between these findings and estimates from other authors' global and hemispheric radiation balance studies and also with energy budget studies of other investigators at Resolute Bay, N.W.T., and at Point Barrow, Alaska. The climate is shown to be one in which latitudinal and seasonal differences account for most of the variation. While during July the storage of heat in the soil accounts for fifteen percent of the energy budget, during the rest of the snow-free season net radiation is nearly balanced by transfer of sensible heat to the atmosphere.
