介绍了南京北郊大气气溶胶观测及其数据分析结果。利用 Raman-Rayleigh-Mie激光雷达系统对南京北郊气溶胶进行常规观测，并对观测数据进行反演分析。详细分析了米氏散射气溶胶消光系数的反演结果随边界值变化的灵敏度，提出了较为准确的气溶胶边界值的确定方法，由此得到较为准确的气溶胶光学参数。通过与地面观测结果的比较，说明了Raman-Rayleigh-Mie激光雷达的观测结果具有可比性，其边界值的确定及其反演方法在一定程度上可信，可行。

This paper presents the aerosol measurements in north suburb area of Nanjing and the analysis results. The aerosol in north suburb area of Nanjing is measured regularly by Raman-Rayleigh-Mie lidar system, and the results are analyzed. Variation of calculation result of aerosol extinction coefficient with boundary value is discussed in detail. The method for selecting more accuracy boundary value is suggested, and based on which, more accurate aerosol extinction coefficient is obtained. By comparing with other ground-based measurement results, it is indicated that aerosol Raman-Rayleigh-Mie lidar measurement results are comparable, and the method for boundary-value selection and aerosol extinction coefficient calculation is reliable.
