   Aerosol and Carbon dioxide Detection Lidar (ACDL) simultaneously emits 532nm and 1064nm and 1572nm three-wavelength double-pulse laser, which can meet the high-precision measurement of aerosol and cloud profiles and CO2 column concentrations. Based on 532nm hyperspectral detection technology (HSRL) to measure The atmospheric aerosol and cloud profiles are measured by HSRL technique at 532 nm and traditional backscattering lidar technique at 1064 nm. The CO2 column concentrations are measured by 1572 nm integrated path differential absorption (IPDA) technology .The two different lidar principles are integrated into the ACDL lidar to measure more atmospheric environment parameters.
