Abstract
Preliminary measurement of the stratospheric aerosol layer using multiwavelength laser radar (λ=0.6943μm and 0.3471μm) are presented. This result suggested that there was noticeable change on the vertical distribution of size distribution and/or chemical composition of the aerosol particles. The contribution of Mie scattering component at λ=0.3471μm to the total scattered light becomes apparently smaller than that at λ=0.6943μm owing to the so-called "dependence of λ-4 in Rayleigh scattering", and this enables us to search out easily the fitting point which is used to distinguish the Mie scattering component from the measured total scattering power intensity.
