Raman and Mie Scattering Aerosol Lidar
DSL-R
The Raman and Mie scattering aerosol lidar adopts a high-efficiency Raman spectral splitting system composed of dichroic mirrors and ultra-narrowband filters. It realizes precise separation and high-efficiency extraction of Mie-Rayleigh scattering signals, as well as vibrational Raman scattering signals of nitrogen and water vapor from atmospheric echo signals received by the lidar. It provides physical parameters including spatiotemporal distribution of aerosols, cloud height and cloud layers, water vapor mixing ratio, and lidar ratio.
Product Applications: An optional outdoor control cabinet is available for this lidar to support unattended real-time outdoor measurement.
Adopting world-leading multi-wavelength and Raman detection technologies, the Raman and Mie scattering aerosol lidar meets the demands of scientific research and routine operational applications in fields such as atmospheric environment monitoring and meteorology and climate study.
Equipped with multiple detection modes, the lidar can capture detailed information of aerosol layers, water vapor and cloud layers. It can quantitatively retrieve atmospheric optical parameters and particle spectra, and determine system parameters like lidar ratio for lidar calibration.
