【摘要】 利用轻便型扫描式的米散射激光雷达对香港地区的大气气溶胶分布进行了测量。该激光雷达可以在10min内,以120°倾角对大气进行扫描,扫描高度为1～4km。用2种计算方法对激光雷达测得的数据进行了分析,分别利用前向法和后向法计算了大气气溶胶的消光系数对高度的变化情况,并把计算结果与理想情况进行了比较,分析后认为后向法更为稳定。更多还原

【Abstract】 By using a mobile volume scanning Mie Lidar, the aerosol in Hongkong was detected. The Li-dar can take slant angle scan of aerosol distribution over 120 degree within 10 minutes and the scans cover a range approximately from 1 to 4 km. In this paper, the data detected by the Lidar were analyzed by two methods: forward method and backward method. The plots of extinction coefficient of aerosol along height using these two methods were compared with the one in ideal atmosphere. From such contrast, we can get the conclusion that the backward method is better.更多还原
