Adding Weather to Your Simulation

Abstract : Simulations and other computer intensive models frequently use limited weather scenarios - either rudimentary in capability or static and unvarying. The Battlefield Environment Division of ARL has been addressing this problem for many years. Capabilities exist in the Tri-Service Integrated Weather Effects Decision Aid (T-IWEDA) and the Target Acquisition Weapons Software (TAWS), in approximate radiative transfer models, such as the Sky-to-Ground Ratio (SGR) model, the illumination model LUME, and in the legacy models of the Electro-Optical Atmospheric Effects Library (EOSAEL). These models will be briefly reviewed and rapid-running methodologies for implementation will be presented. A complete set of references is also included.
