MODELLING SOLAR RADIATION IN STEEPLY SLOPING TERRAIN

摘要: A methodology for predicting global shortwave radiation into any slope based on the ratio of incoming to horizontal and exoatmospheric beam is described. The model individual calculations direct diffuse components, enabling its application under a wide range sky conditions. An algorithm accounting effect topographic shading also included this enables accurate estimations spatially distributed in steep sided terrain. then applied summer winter solstices at Monachyle catchment Balquhidder, Scotland. Although incident strongly affected by angle aspect, influence seasonal more dependent upon overall orientation. In winter, areas receive only radiation, emphasizing importance modelling components individually.
