MULTIPLE-SCATTERING AEROSOL LIDAR INVERSION METHOD

The multiple-scattering contributions to lidar aerosol backscatter returns are measured by simultaneous detection at four concentric fields of view. A solution method is proposed to calculate, from the ratios of the lidar returns at the different fields of view, the range-resolved scattering coefficient. The method also provides the effective size of the aerosol particles responsible for the forward peak of the scattering phase function. Solutions from measurements performed in fog and clouds with a 1.054 mum lidar system are presented.
