| Abstract(in English) | Two-channel direct detection techniques of aerosol and molecular backscatter are compared for global wind vector measurements by the space borne Doppler lidar system. Parameters of the etalon filter are optimized by minimizing the velocity error. The lidar systems with the fundamental, 2nd and 3rd harmonic wavelength of the Nd:YAG laser are compared. The fundamental wavelength laser can be used for aerosol wind measurement and the UV wavelength is superior for the molecular detection. The velocity accuracy of 3m/s is obtained up to 9km with the aerosol measurement, and the accuracy of 2～3m/s is possible up to 10km with the molecular Doppler measurement. |
