The Environmental Scenario Generator

.The availability of a turnkey environmental scenario generation process is essential to the success of DoD simulations. The process must be robust, efficient, and repeatable; but also be highly customizable and flexible to support the wide range of scenario requirements likely to evolve over the coming years. The Environmental Scenario Generator (ESG) provides an automated capability for the generation of integrated and physically consistent environmental data sets meeting a Modeling and Simulation customer's requirements for an authoritative and realistic representation of atmospheric, oceanic, and/or space natural environment elements for specified regions, time frames, and conditions. The ESG architecture consists of an intelligent search mechanism to locate desired conditions in reference databases and a just-in-time production capability to provide authoritative representations of the environment when none exist off-the-shelf. ESG leverages the Master Environmental Library (MEL) program by integrating the MEL Software Development Kit into its architecture, providing the ability to utilize the data and modeling resources available through MEL for both data mining and scenario production. The ESG is being developed as one of the keystone technologies under the DMSO Integration Strategy for defining how natural environment data will flow from data providers to DoD M&S users. This paper will provide an overview of the ESG data mining capabilities and scenario production framework, including the specific data and modeling resources implemented in FY-99
