Abstract
Measurements of the depolarization ratio of water droplets were performed to study the relationship between layer integrated depolarization and layer integrated backscattered light for linear and circular polarization illumination. Since those particles are spherical, the depolarization of the signal is attributed to multiple scattering effects. The experimental data reported in this article support Hu relationship between the single scattering fraction As and the linear accumulated depolarization ratio. For circular polarization, a modified Hu relationship is established and it is shown that the use of the accumulated depolarization parameter instead of the accumulated depolarization ratio allows harmonization of the linear and circular polarization measurements into a simple mathematical expression.
