Paper Abstract

The error of retrieving the aerosol backscattering ratio with partial Raman spectrum is calculated in present paper. A new method is presented for reducing the error. One low-level and one high-level spectrum line are chose to make up a new pseudo-line independent on the temperature. Finally, aerosol backscattering coefficient ratio profiles of the atmosphere were obtained from the signals of a rotational Raman Lidar in our lab. The results show that Tropospheric aerosol backscattering coefficient ratio can be retrieved by using the new rotational Raman pseudo-line without considering the relation between aerosol extinction and backscattering.
