One of the important parameters used to estimate Urban Heat Island that involved with mesoscale model is albedo. It is useful to reliably investigate the energy budget in an urban through the radiation exchange study within urban canopy. In order to systematically clarify the urban albedo characteristics coupling with that of factorial effects, we introduce an Albedo Calculation Model, which is simple and more reliable to provide the 3-dimensional urban albedo simulation. In addition, the numerical experiment based on the model was carried out for supplementary explanation of how the significant factors affect albedo characteristics. In this paper, the principle of Albedo Calculation Model and associated numerical experiment results are obviously described.
