- This case describes structure of solar radiation balance in Ny-?lesund, Spitsbergen, basing on twenty-four-hour?s magnitudes in 1989-2003. We put to the analysis each radiation streams: shortwave and longwave. Basing on it one year?s and monthly balances were estimated: (K*, L*, Q*). The radiation data used in this article are derieved from: Norsk Polarinsitutt in Oslo: Hisdal, Finnekasa and Vinje (1992) and Hisdal and Finnekasa (1996); 'The Alfred Wegener Institute for Polar and Marine Research': Koenig-Langlo and Marx (1997). The data of clouds from Ny-Alesund are derieved from: Climatolology Division, Norwegian Meteorological Institute, Norway. In 1989-2003 period - annual radiation balance Q* in whole spectrum was oscillating from - 71 MJ/m2 to 194 MJ/m2, average Q* was 57 MJ/m2. Highest values of Q* in year are recorded on June, July - average - 210-260 MJ/m2, lowest on polar night period -October-February (-87 MJ/m2 to -100 MJ/m2). Short-wave radiation balance K* was depending on sun level, sculpture of the earth?s surface and cloudiness modify amount of downward sun energy. Yearly balance sums of short-wave radiation K* was oscillating from 931 MJ/m2 to 1438 MJ/m2, average -1178 MJ/m2. Yearly course of stream K and balance K* shows maximum from April to August and zero values in November-February period. Analyzing many year?s estimation -highest yearly sum of K stream - 2634 MJ/m2 - was recorded on 1993 and lowest - 2157 MJ/m2 on 1990, average of sums in this period was - 2402 MJ/m2. Average yearly balance of L* was 1120 MJ/m2 on 1989-2003 period. Annual balance sums were oscillating from -936 MJ/m2 to -1265 MJ/m2.
