兴隆大气视宁度测量

The Measurement of Atmospheric Seeing at Xinglong Observation Station

本文报导了在北京天文台兴隆观测站分别用校差图像运动（DIMM）、星像亮度半峰值全宽度（FWHM）、温度脉动探空（TFS）、声雷达四种不同的测量方法对当地的大气视宁度进行观测的结果。观测资料证明，这几种方法之间有很好的相关性，而且DIMM与TFS之间在定量上也很符合。

The measurement results of atmospheric seeing with different methods, including differentail image motion monitor(DIMM), full width of half maximum image brightness(FWHM), temperature fluctuation sonde(TFS), and acoustic radar(AR), at XinglongObservation Station of Bejing Observatory are reported in the paper. The measurementdata show that the correlation between them good, and there is a good quantitave consistency between DIMM and TFS.
