利用拉曼-瑞利-米激光雷达对南京北郊雾霾气溶胶进行观测和分析，并和气象预报相比对。2009年12月2日进行了长时间连续的观测实验，分析比较2009年12月2日观测的雾霾激光雷达距离矫正信号和2011年1月10日南京北郊晴空大气边界层气溶胶激光雷达距离矫正信号的区别和特征。实验结果表明：2009年12月2日10：00至19：00观测出现雾霾，激光雷达观测到雾霾出现的时间段和当天南京气象预报相吻合；南京北郊雾霾出现在低空300 m左右，厚度大约为700 m，大气边界层气溶胶出现的高度为1 000 m左右，厚度大约为1 500 m。

This paper presented the fog-haze measurements by Raman-Rayleigh-Mie lidar in north suburb of Nanjing, the measurement results were analyzed and compared with the weather forecast. Continuous measurements were carried out on 2/12/2009, it was clear day from 01:00 to 08:00 in the morning, and foghaze was measured from 10:00 in the morning to 19:00 in the evening. The fog-haze measurement results coincided with the weather forecast on that day. The fog-haze lidar measurement results on 2/12/2009 were analyzed and compared with the boundary aerosol measurement results on 10/01/2011, the differential characters of range-corrected-signals between fog-haze and boundary aerosol were discussed. It is shown that fog-haze usually occurs at about 300m height with a depth of 700m and boundary aerosol usually occurs at about 1000m height with a depth of 1300m in Nanjing.
