| 摘 要： | 为了改进乃至革新大气能见度的探测技术,探索新型、快速、准确测量大气能见度的方法,采用自行研制的能见度微脉冲激光雷达,进行了水平大气能见度测量实验,并同已经商品化的能见度仪NQ-1进行了同步对比测量。实验结果表明,在水平能见度较差时,微脉冲激光雷达和能见度仪具有很高的相关性,相关系数达到了0.88;在水平能见度较好的时候,相关系数保持在0.73以上。说明能见度微脉冲激光雷达系统可以应用于大气能见度的探测。

| Abstract: | In order to improve the technology in atmosphere detection and explore new,faster,and more accurate methods to retrieve atmosphere visibility,the atmosphere visibility was simultaneously measured in Qingdao with a micro-pulsed lidar,designed by Ocean Remote Sensing Laboratory,Ocean University of China,and a NQ-1 commercial visibility meter respectively.The results indicate both has a high correlation coefficient up to 0.88 when the visibility is poor or moderate and the their correlation coefficients are above 0.73 in good visibility conditions,which indicates it is feasible for micro-pulsed lidars to measure the visibility. |

| Keywords: | atmospheric and ocean optics correlation coefficient extinction coefficient atmosphere visibility micro-pulsed lidar(MPL) visibility meter |
