A new method is proposed for the obtaining multi-wavelength aerosol optical characteristics by using visibility meter (VM),optical particle counter (OPC) and micro pulse lidar(MPL).The refractive index of λ=0.532μm is retrieved by extinction coefficient.The ratio of extinction-to-backscatter and number density distribution of aerosol particle measured by VM,OPC and MPL,and the refractive index of other wavelength can be obtained by mode using the initialization value of λ=0.532μm.So some other wavelength aerosol optical characteristics can be obtained by using Mie theory.This paper also provided the aerosol optical characteristic vertical distribution of 0.532μm,1.06pm and 10.6μm according to results of extinction coefficient vertical distribution measured by MPL in Beijing.
