“…2) there clearly is a fair amount of energy at those angles. The subtraction of the higher order scattering energy found at those specific angles, when done at all azimuths, leads to a second order scattering pattern [4]. So, it appears that multiple scattering effects occurring in dense water cloud can be simplified to second In the following, we will examine what are the mechanisms leading to depolarization of the lidar signal from second order scattering.…”

Under single scattering conditions, water droplets clouds do not depolarize the backscattered light. However, backscattered light from multiple scattering will be depolarized. The level of depolarization is a function of the droplets size and of the cloud extinction coefficient value and its profile; it has also a strong dependency on the lidar field-of-view (FOV) and azimuth angle [1]-[3]. It has been demonstrated in [4] that the multiple scattering cross polarization signal can be reduced to a second order scattering one using the azimuthal dependency of the cross polarization. In this paper we present how the multiple scattering cross polarization can be reduced to a second order scattering and how this signal is related to the droplet particle size. Monte Carlo simulations for clouds at different ranges and effective radius sizes are performed and compared with the results obtained with an analytical model.
