Depolarization ratios retrieved by AERONET sun–sky radiometer data and comparison to depolarization ratios measured with lidar

The linear particle depolarization ratios at 440, 675, 870, and 1020 nm were derived using data taken with the AERONET sun–sky radiometer at Seoul (37.45 N, 126.95 E), Kongju (36.47 N, 127.14 E), Gosan (33.29 N, 126.16 E), and Osaka (34.65 N, 135.59 E). The results are compared to the linear particle depolarization ratio measured by lidar at 532 nm. The correlation coefficient R2 between the li...

Reviewer #2 General comments This article addresses a problem of dust particles detection in the atmosphere, which is of high interest of scientific community. A new method for quantitative estimation of dust presence based on particle depolarization ratio retrieved from AERONET inversion is suggested. Authors made significant efforts to evaluate the AERONET retrieved particles depolarization r...

Classification of particle effective shape ratios in cirrus clouds based on the lidar depolarization ratio.

A shape classification technique for cirrus clouds that could be applied to future spaceborne lidars is presented. A ray-tracing code has been developed to simulate backscattered and depolarized lidar signals from cirrus clouds made of hexagonal-based crystals with various compositions and optical depth, taking into account multiple scattering. This code was used first to study the sensitivity ...

A Scheme to Classify Clouds with the Depolarization Ratio and Backscattering Coefficient Measured by Lidar

The optical properties of clouds were measured with a polarization Mie lidar during April, 2004 and investigated to categorize the particles detected by the lidar. The cloud layers were categorized into five types according to the depolarization ratios, as follows: (I) constant and small (less than 5%); increasing with height (II) nearly from 0% and (III) from about 50%; (IV) large and varying ...
