UV-depolarization Lidar remote sensing experiment analysis using scattering matrix formalism

Abstract

In this paper, an optical remote sensing method is proposed to retrieve the number concentration of non spherical volcanic ash particles. An UV-polarization sensitive remote sensing experiment is interpreted in the frame of the scattering matrix formalism. It follows that UV-optical scattering and depolarization, when they are used together and in correlation with laboratory measurements on scattering matrix elements, are meaningful to retrieve information on volcanic ash particles such as shape or number concentration.
