Vertical distribution of aerosol extinction cross section and inference of aerosol imaginary index in the troposphere by lidar technique.

Vertical profiles of aerosol extinction and backscatter in the troposphere are obtained from multi-zenithal angle lidar measurements. Regression analysis with respect to zenith angle for a layer integration of the angle-dependent lidar equation was thus employed to determine the optical thickness and aerosol extinction-to-backscatter ratio for defined atmospheric layers, and subsequently, cross-section profiles could be evaluated. -from Authors
