Abstract

A prototype Raman lidar was designed for monitoring tropospheric CO<sub>2</sub> profile and other scientific investigations. The third harmonic of Nd:YAG laser (354.7-nm wavelength) was used as stimulated light source to provide nighttime measurements. Filter with high rejection ratio performance was used to extract CO<sub>2</sub> Raman signals from Rayleigh-Mie scattering signals effectively. To improve the real time monitoring function, a two-channel signal collection system was designed to collect CO<sub>2</sub> and N2 Raman scattering signals simultaneously. The N2 Raman scattering signals were used to retrieve aerosol extinction coefficient. Typical features of CO<sub>2</sub> concentration profile and aerosol extinction coefficient in Hefei were presented. The mixing ratio of atmospheric CO<sub>2</sub> in Hefei can reach about 360-400 ppmv.
