摘要:The article presents the methods for the elaboration of the map of quasiglobal radiation in detail. The basis for the elaboration of the map is rastered Geographical Information System. Among meteorological data sources, the most important are those measuring the duration of solar radiation. We used mean ten-day period hour values in the period between 1961 and 1990 from twenty-four meteorological stations in Slovenia. The source of relief data is the 100×100 meter digital relief model from which we calculated the inclination, exposition, and level of shade. The final map clearly shows the differences in the annual energy of quasiglobal radiation at various relief positions and climate regions.f
