  • In genneral, Businger expression is used for determining a turbulance diffusion coefficient. In this study, it is applied to the surface elements of cities such as Asphalt, Cround, Grass, Pond. We set up 5 m-height bar and measured the ary temperature and wet temperature at 도 height of 0.13, 0.27, 0.5, 1, 0, 3.0, 5.0m. In addition we measured the wind gradient and wind velocity at the height 3 m solar radiation continuously for 48 hours on the surface. Compared the measured data to Businger expression the result showed that Businger expression can be well applied to the complex surface of the city.
