Vertical laser beams are often used at ground-based cosmic ray observatories employing the fluorescence technique for characterizing the height-dependent properties of the atmosphere, as well as for calibration and telescope alignment studies. The light flux received at a detector from a laser is typically assumed to be only singly scattered out of the beam, with no possibility for the multiple scattering of photons initially scattered in other directions back into the detector's field of view. We present the results of a new simulation for the scattering of light from a vertically-directed laser beam, and derive a parametrization for the multiple scattered signal expected at a detector from such a source as a function of the prevailing atmospheric conditions. The parametrization is then used to estimate the increase in the reconstructed height-dependent aerosol loading when recovered using a laser-based technique.
