Abstract : Uncertainties in modeling meteorological influences on smoke/obscurant concentrations are evaluated. Three components of modeling uncertainty are identified--input data uncertainties, random or stochastic uncertainties, and uncertainties due to model formulation. A method is proposed for analyzing smoke/obscurant field tests in order to determine whether there is a significant difference in source emissions between groups of tests. The method is tested using measurements from several field experiments, including U.S. Army smoke/obscurant tests. This scheme may also be applicable to other scientific endeavors where confidence limits on measured and-predicted data must be assessed.
