Modeling Obscurants in an Urban Environment

Abstract

Line of Sight obscuration effects of smoke, dust and debris on target acquisition are difficult to model in an urban environment. Wind flow and buoyancy in urban street canyons can be complex. This paper outlines the obscuration model being developed by the U. S. Army Research Laboratory for the NATICK RDEC to support the next generation of the Infantry Warrior Simulation (IWARS). It uses the legacy COMBIC obscuration model sources and STATBIC concentration redistribution approach to simulating turbulence effects. The ARL-developed mass-consistent urban 3D Wind Field (3DWF) model is used to provide urban wind field inputs. Various techniques are described to adjust aerosol cloud concentrations for the effects of buildings as they confine the cloud to the streets.
