N2 - As the extinction coefficient is related to directly many atmosphere character, it is important to get extinction coefficient of atmosphere. Lidar has been proven to be a kind of useful method for remotely sensing the optical properties of atmospheric aerosols. The relationship between the Mie backscattering signal intensity and the detection range can be accurately achieved by Mie Lidar, and the atmospheric aerosol extinction coefficient can be retrieved from the backscattering signal. In this paper, a practical 532nm system of Lidar on the basis of MIE and Raman scattering, which consists of laser transmitter, signal receiver and data processing system, is presented and some experimental results have been gathered. In last some years, there are many data processing methods in inversion of aerosol extinction coefficient. Among these algorithms, Fernald inversion method is adopted abroad to obtain optical parameters in inhomogeneous atmosphere. This paper discusses the data processing method gives the extinction coefficient profile. At last, the effect of some estimated parameters is discussed.
