Monte Carlo model of cloud scattering of solar radiation for aircraft VLC systems

With the raising interest in aircraft-based visible light communication (VLC) systems, characterizing the amount of sunlight scattered by clouds becomes important for modelling the incoming solar radiation. In fact, sunlight comes through the aircraft windows and affects the receivers as a form of disturbance. In this regard, this paper proposes a Monte Carlo photon transport simulator that provides the spatial scattering function of a water cloud with an arbitrary liquid water content, when it is illuminated by the sunlight coming from a given direction.
