A portable Micro-pulsed Mie scattering lidar at the laser wavelength of 532 nm has been developed for routine observation of atmospheric optical properties of the lower troposphere, including boundary layer structure, cloud, the distribution of aerosol and horizontal visibility and so on. The configuration of lidar and its design methods including the hardware and software were described in details. The lidar system was controlled by compact computer, including self adjustment for coaxial lidar, three-dimensional scanning, real-time data processing of visualization and inversion online. The experimental results illustrate that the system can measure the atmospheric aerosols up to the range of near 5 km at daytime and up to 15 km at nighttime under the measurement conditions of laser energy of 50 μJ, signal averaging time of 40s, a receiving aperture 254 mm, range resolution of 7.5 m and analog detection model, which can provide scientific measurement data for studying the atmospheric environment change, particularly for resolving the particulate pollutant generation, transmission and diffusion characteristics.
