AGHJ-I-LIDAR Atmospheric Particle Monitoring Lidar (Dual Wavelength Three Channel Series) Introduction
The laser emits laser pulses of a specific wavelength (532 nm, 355 nm), which are collimated and expanded into the atmosphere. The particles in the atmosphere scatter the laser to the laser. The detection system detects the echo signals of the three channels and then the echo signals. Inversion is performed into extinction coefficient and depolarization ratio (depolarization ratio). A comprehensive graphical display of the spatio-temporal evolution of fine particles, combined with near-surface data, can comprehensively analyze the pollution process and pollution characteristics of local particulate matter in a local area, and effectively distinguish the relationship between local pollution and external transportation.
Based on the principle of rice scattering, the concentration and spatiotemporal distribution of the particles are detected. Widely used in the field of atmospheric environment stereo monitoring, meteorological observation and scientific research. Features
