Modelling solar radiation patterns for stand-scale studies in complex terrain
2009
International audience; A spatial model has been developed to simulate stand-scale patterns of irradiance over an hilly terrain bounded by a forest. Conceptually, the model is based on semi-empiric radiation equations and efficient viewshed algorithm further improved to account for sloping terrain and the presence of the forest. Model performance was assess on both radiometry and geometry. Comparison shows good agreement with observations. Model experiments were conducted for cloudy-less condition (i.e. at potential) along whole vegetative period of grapevine stand. Anal- ysis of deficit of irradiance for year 2003 shows that patterns are mainly due to the presence of the forest implying stron…
