Natural Environmental Effects in Military Models and Simulations: Part III - AnAnalysis of Requirements Versus Capabilities

摘要

The Defense Modeling and Simulation Office has sponsored the EnvironmentalEffects for Distributed Interactive Simulation (E2DlS) Project, which is composed of eight tasks including the Survey Task. The Survey Task had three objectives: to develop a baseline of the Military Services' current requirements for incorporation of the atmosphere and near space environment and their effects in military models and simulations (the Requirements Survey), to identify atmospheric and near-space-environment models and databases and environmental effects models and databases that are currently available from the services (the Capabilities Survey), and to compare the results from both survey efforts and make appropriate recommendations. This report, Part III of a three-part series, describes the results of a comparative analysis of the two surveys, whose results are reported in Part I (the Requirements Survey) and Part II (the Capabilities Survey). The analysis focuses on the eight most-needed types of environmental data, as determined from the Requirements Survey, and shows that the capabilities for providing these data, especially at high fidelity, are deficient. Requirements and capabilities are compared in terms of their horizontal, vertical, and temporal fidelity. Capabilities are deficient if they satisfy less than 75 percent of the requirements. The most significant deficiencies are found in models and databases of aerosols, fog, humidity, and visibility.
