Description:
This article presents the results of observations of selected fluxes of the
radiation balance in north-western Spitsbergen in the years from 2010 to 2014. Measurements
were taken in Ny-Ålesund and in the area of Kaffiøyra, on different surface
types occurring in the Polar zone: moraine, tundra, snow and ice. Substantial differences
in the radiation balance among the various types of surface were observed. The
observations carried out in the summer seasons of 2010–2014 in the area of Kaffiøyra
demonstrated that the considerable reflection of solar radiation on the Waldemar Glacier
(albedo 55%) resulted in a smaller solar energy net income. During the polar day,
a diurnal course of the components of the radiation balance was apparently related to
the solar elevation angle. When the sun was low over the horizon, the radiation balance
became negative, especially on the glacier. Diurnal, annual and multi-annual variations
in the radiation balance have a significant influence on the functioning of the environment
in polar conditions.
