Multiple Scattering Effects upon Measurements with the AFGL LSRVMS Lidar System.

Abstract

This report describes Monte Carlo calculations that were made to determine the effects of multiple scattering on the meteorological ranges (visibilities) obtained through a single-scattering analysis of the measured time-dependent signals to be obtained from the AFGL LSRVMS lidar system. Multiple scattering was found to affect the accuracy of visibility measurements in both radiation and advection fogs for low visibilities such that the visibility obtained from the experiment is higher than the true visibility. The deviation of the computed visibility from the true visibility was small (1 to 4%) for the radiation fog model at all visibilities studied, but for the advection fog the deviation of the computed visibility from the true visibility varied from 15% to 2% as the true visibility varied from 50 meters to 1000 meters.
