Three-dimensional meteorological meso-scale model is often used to solve the mechanism of urban heat island. On the meso-scale analysis, one-dimensional heat balance model is used mainly as ground boundary conditions. However it is necessary to include the effects of building canopy exactly in order to analyze thermal environment at pedestrian level in urban area. On the other hand, one-dimensional urban canopy model is also used commonly to analyze urban climate. This model can predict thermal environment at pedestrian level easily. However it is impossible to analyze three-dimensional property of climate including effects of advection and diffusion by this model due to the assumption of horizontally homogeneous flow and temperature field. In this paper, meteorological meso-scale model is incorporated with the urban canopy model as the boundary conditions. The 3D detailed digital map information is utilized for representing the building canopy model. The urban thermal environment in Tokyo metropolitan area is analyzed by means of this new method proposed here and the structure of urban heat island is clarified.
