Abstract: | We propose a high spectral resolution lidar system which is capable of measuring aerosol backscattering and line-of-sight wind velocity in the troposphere. An iodine vapor filter is used to separate the aerosol and Rayleigh scattering components as well as to discriminate the Doppler shift frequency. The performance of the lidar system is estimated with reasonable parameters. The error of horizontal wind velocity below an altitude of 6 km is less than 0.5 m/s, and accuracy of the aerosol backscattering coefficient is better than 40% below 10 km. This system is particularly suitable for the study of aerosol transportation in the troposphere. |
