Abstract

A model has been developed which describes the degradation of visibility due to battlefield aerosols. Emphasis is placed on the diffusion and transport of the aerosols and their effect on visibility degradation at locations remote from the sources. The starting point which we describe here is a simplified approach designed to evaluate the interplay between particle and meteorological components of the model and to obtain an order of magnitude estimate of the potential for visibility degradation due to battlefield aerosols. The one-dimensional meteorological model includes atmospheric turbulence and radiation effects and describes the diurnal development of the planetary boundary layer. The particle model adopts a Monte Carlo approach with 1,000 pseudo-particles (small air parcels containing many aerosol particles) released into the atmospheric conditions generated by the meteorological model. The full solution of this problem will require a meteorological model in three dimensions with a dynamic development of synoptic conditions on the regional scale.
