註釋

The paper discusses adverse & favorable effects of multiple scattering in lidar (laser infrared radar) measurements. Adverse effects arise because the conventional lidar equation ignores multiply scattered 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 measurements of atmospheric ozone profiles in the presence of cirrus clouds & ground layer aerosols. On the other hand, multiple scattering contributes additional information on the aerosol extinction coefficient & particle size. The paper shows how this can be exploited to derive simultaneous solutions for the extinction coefficient & mean particle diameter independently of external data, as required in conventional solution methods.
