Outline of Final Research Achievements

Subsurface temperature monitoring was conducted by use of high-precision thermometers to evaluate the formation process of urban subsurface warming in the Tokyo metropolitan area. Continuous subsurface warming was observed, and it was made clear that subsurface warming become advanced. The warming ratios of subsurface temperature in the city center were higher than the warming ratios in the rural area. The formation of subsurface warming was considered to be affected by not only the surface warming but also waste heat from subsurface structures and groundwater flow changes.
