Abstract
The contrast in the azimuthal pattern of cross-polarized lidar data is used directly to retrieve the extinction coefficient profile of water droplet clouds. Using a Monte Carlo simulation, we demonstrate that there is a simple mathematical relationship between the optical depth and the contrast of the cross-polarization azimuthal pattern. This relationship is independent of the water cloud droplet size, cloud position, and extinction profile. The derivation of the extinction profile of a water droplet cloud is obtained directly using the simple mathematical relationship without performing lidar equation inversion. The technique is limited to spherical particles.
