Abstract

In this study, long and short-wave radiations were observed in urban and suburban areas during the summer season, and frequency analysis was performed for each radiation intensity by a new analysis method. The following results were obtained. ① Long-wave radiation values were found to be larger in the afternoon than in the morning, in both urban and suburban areas, unlike short-wave radiation values. ② Short-wave radiation showed a right-skewed frequency distribution. In the high energy area greater than 900 W/m2, the frequency was significantly higher in the suburbs than in the urban areas. ③ Long-wave radiation was in the range of 290∼479 W/m2, its frequency distribution resembled a normal distribution, and the frequency of 410, 420 W/m2 was the highest.
