The paper presents the dependences of the spectral ratio on the particle size for four shapes at six wavelengths. The study was conducted using the extended database of light scattering matrices of the IAO SB RAS, on data obtained within the physical optics approximation, for the case of random spatial orientation of particles and single scattering. Several particle shapes, which are typical for ice clouds, were studied at wavelengths of incident radiation from 0.355 to 2.150 μm. The results of this work can be used for interpretation of the lidar signal, in particular, to retrieve the size of atmospheric ice particles.
