Continuous measurement of downward infrared radiation has been rather limited in urban area. In this study, downward infrared radiation was observed at Tokyo area. Data were compared with those observed operationally at suburban area (Tsukuba City). One-hour mean radiation in clear sky condition at Tokyo was larger approximately 3 Wm^-2 than those observed at Tsukuba and the difference was statistically significant. Additional investigation including numerical simulation showed that the difference in downward infrared radiation was related to the vertical temperature profile near land surface and its diurnal variation. Estimated influence of aerosol concentration difference between the sites was small

在城市地区，向下红外辐射的连续测量相当有限。在这项研究中，在东京地区观察到了向下的红外辐射。数据与郊区（筑波市）实际观察到的数据进行了比较。东京晴空条件下的一小时平均辐射比筑波观测到的高约 3 Wm^-2，差异具有统计学意义。包括数值模拟在内的进一步研究表明，向下红外辐射的差异与地表附近的垂直温度剖面及其日变化有关。站点间气溶胶浓度差异的估计影响较小
