Product Introduction: This product is a high-energy (mJ level) dual-wavelength triple-channel aerosol lidar. It uses laser as the light source, simultaneously emitting 355 nm and 532 nm lasers. The receiving telescope collects the backscattered signals from aerosols, analyzing the echo signal strength and polarization characteristics through the reception of the 355 nm extinction signal and two 532 nm depolarized signals (vertical and parallel). This allows for the determination of aerosol particle physical properties (identifying particulate matter, dust, ice clouds, water clouds, etc.), as well as the extinction coefficient, depolarization ratio, wavelength exponent, boundary layer height, aerosol optical thickness, and cloud information. The product is designed for continuous monitoring of atmospheric aerosols, particularly observing the entire process of particulate pollution formation, development, decay, and dissipation during haze events. It helps to understand the interaction processes between near-surface particulate pollution and the distribution of particles within the boundary layer (such as downward settling or upward transport). This data supports further understanding of particulate pollution dispersion patterns and the causes of near-surface particulate pollution, providing decision support for environmental protection and meteorological departments. The system can be installed in a fixed position (indoors or outdoors) or used in a vehicle-mounted configuration.
