MWRA 12K Raman and Mie Scattering Aerosol Lidar is based on the principles of Mie Scattering, Raman Scattering and Aerosol Particle Deflection to accurately detect atmospheric aerosol optical information.
The lidar system includes three emission wavelengths: 355nm, 532nm, and 1064nm. The receiving system processes the backscatter signals from Mie scattering and Raman scattering to obtain specific physical information about atmospheric aerosols. The multi-wavelength measurements enable a more detailed and accurate study of the microphysical characteristics of atmospheric aerosols. Additionally, the lidar can measure aerosol depolarization signals and water vapor mixing ratios, allowing for a close connection between the optical properties of aerosols and their shape, thermodynamic phase, and hygroscopicity.
It is suitable for environmental, meteorological, and scientific research fields, such as local high pollution monitoring, atmospheric haze process studies, atmospheric composition change monitoring, meteorological pollution impact analysis, and particulate formation mechanisms.
