Bulk Chemical Source Term Accuracy Requirements

Abstract

Traditionally, chemical weapons effects analyses have assumed a lognormal agent drop size distribution. Used widely within the weapons effects sciences, the lognormal distribution is a relatively simple mathematical expression fully defined by only two numerical parameters: in essence, a mean and a standard deviation, or, in the proper terminology, a droplet Mass Median Diameter (MMD) and a geometric sigma. It has until recently appeared to describe adequately the drop sizes observed from legacy test results, and the method used in MDA's Post-Engagement Ground Effects Model called upon the Soltisz model to predict the MMDA as a function of agent characteristics, reentry speed, and release altitude.
