Observation and productization of the micro-pulsed Mie scattering lidar system

Abstract

Abstract:

A Micro-pulsed Mie scattering lidar system operated in analog detection mode was designed and built for routine observations of aerosol optical properties and cloud in the lower troposphere, particularly in the high intense aerosol gathered atmospheric area. The configuration of lidar and its design methods including the hardware and automatic control and data acquisition software were described in details. The experimental results in Xi’an area 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 50μJ, signal averaging time of 40 s, a receiving aperture 254 mm, range resolution of 7.5 m and analog detection model. It can provide scientific measurement data for studying the atmospheric environment change, particularly for resolving the particulate pollutant generation, transmission and diffusion characteristics.
