Paper Abstract

This paper discusses adverse and favorable effects of multiple scattering in lidar measurements. Adverse effects arise because the conventional lidar equation ignores multiple scattering radiation. Hence, the parameters retrieved under this approximation are in error by an amount that depends on the multiple scattering strength. This is illustrated by numerical simulations of space-based DIAL measurements of atmospheric ozone profiles in the presence of cirrus clouds and ground layer aerosols. On the other hand, multiple scattering contributes additional information on the aerosol extinction coefficient and particle size. The paper shows that this can be exploited to derive simultaneous solutions for the extinction coefficient and mean particle diameter independently of external data as required in conventional solution methods.
