Visibility measurement over the horizontal path by means of micro-pulsed lidar

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.
