Abstract
The objective of this study was to compare and analyze for seasonal long short-wave radiation characteristics between downtown area and suburban area in Daegu through field observations. This study was confirmed the regional and seasonal radiation environments and it can utilize as basic data for the analysis of the urban radiation environment and the effects of urbanization. The followings are main results from this study. 1) The downward shortwave radiation showed the similar value of the radiation generally in the downtown area and the suburban area of the city during the winter and summer season. but, long-wave radiation is always higher in downtown area. 2) In case of the long-wave radiation at two stations, we observed $230{\sim}270W/m^2$ in the winter season and $415{\sim}470W/m^2$ in summer season. As a result, we can see summer season is higher than winter about two times in long-wave radiation. 3) In case of short wave radiation, there is high correlation between two stations in winter season but very low correlation between two stations in summer season because of local atmosphere unstability and etc.
