Abstract应大口径红外望远镜选址需求,研制了一台红外辐射测量设备,对丽江天文观测站及澄江M′波段(4.605~ 4.755μm)大气红外辐射与消光特性进行了实测。用Allan方差法和大气辐射传输方程分别对大气辐射的时间和空间变化数据进行了分析,讨论了辐射时空变化对红外天文观测的影响。结果表明,低频区的辐射涨落较大,Allan方差随积分时间呈指数增加,丽江和澄江的Allan方差拟合参数分别为0.794和1.238。从天顶到60°天顶角,丽江和澄江站的辐射亮度分别增大了68%和72%,透过率分别降至0.46和0.52;红外天文观测需斩波,在丽江站,探测器单像元、2×2Binning、4×4Binning最佳斩波频率分别为0.030,0.070,0.144Hz。实测所得Allan方差、大气消光、最佳斩波频率可用于指导大口径红外望远镜的选址及设计。
