An Atmospheric Turbulence Profile Model for Use in Army Wargaming Applications I
Abstract
Models for the vertical structure of the refractive index structure parameter, Cn2, appropriate for wargames are discussed. Legacy vertical profile models are reviewed and synthesized to produce a new vertical model that seamlessly spans various segments of the tropospheric atmosphere. The model integrates effects for the surface, boundary, and upper tropospheric layers. Legacy models are reviewed and synthesized to create the new profile model. In this effort the focus has been on the worst case condition near the surface of daytime noon turbulence. The model developed is suitable to simulate turbulence effects on Army electro-optical sensors for visible through far-infrared wavelengths. The products of this study is a tailored, small, rapidly executing algorithm and associated tables for predicting turbulence: a log-mean vertical layer and terrain effects prediction, and a methodology for conversion of the log-mean profile to mean Cn2 profile.
