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.
