The product is based on the Raman-Mi scattering principle, adopts a three-wavelength eight-channel design, and uses the N2 and H2O Raman scattering receiving channels to realize the collaborative observation of parameters such as high-precision aerosol and water vapor mixing ratio, detect the vertical distribution of atmospheric aerosol (sand and dust) and the space-time evolution process, and provide support for the short-term forecast warning of strong convective weather.
