摘　　要：Coherent lidar(CL)addresses existing constraints in CL data products by enabling simultaneous observation of multiple meteorological parameters such as cloud height,extinction coefficient,aerosol concentration,and wind field evaluation.A detailed analysis of CL echo signals was performed at a wavelength of 1550 nm,enabling accurate measurements of cloud height and aerosol concentration.Extensive data analyses and validation tests were conducted,aligning them with a 532 nm direct aerosol lidar(AL).The assessments of the aerosol extinction coefficient demonstrated notable consistency.This underscores the potential of advanced CL for providing prolonged and consistent observations across diverse meteorological conditions.

关 键 词：coherent lidar aerosol extinction coefficient aerosol concentration WIND
