利用中国气象局南京综合观测基地的Rayleigh-Raman-Mie激光雷达Mie通道实测数据反演分析南京北郊气溶胶光学消光特性。对2013年11月至12月雾霾天气进行观测并分析得到光学消光系数，并结合CALIPSO卫星搭载的激光雷达CALIOPSO level.2分类产品数据进行消光特性参数分析。利用CALIPSO监测2012年冬季一次沙尘过程所得结果与地基微脉冲偏振激光雷达结果一致。

Analysis of the optical extinction characteristics of aerosol in Nanjing by using the data from the Mie channel of Rayleigh-Raman-Mie Lidar,which belong to the Comprehensive Observation Base of China Meteorological Administration, is presented in this paper. We observed and calculated the optical extinction coefficient of haze from November to December in 2013 by Lidar, and analyzed the optical extinction parameter properties by using the data from CALIPSO level.2. Comparing the inversion results of winter dust in 2012, the results obtained by using CALIPSO and the micro-pluse Lidar are consistent.
