Abstract:Considering different solar radiation between various areas and terrain, and att
enuation by terrain, atmosphere and other factors, along with the newly
research trends, based on slope, aspect and shadow derived by DEM, a model of p
otential solar radiation in Shanxi Plateau is established. By comparing with the
daily solar radiation observed in three observation stations in 5 years, the re
sults show that the model is feasible. The model was used to analyze the spatial
and temporal distributions and variation of potential solar radiation in Shanxi
Plateau. The model could also provide critical foundation for research of microc
limate variation and microclimate index.
