AER will present results from ongoing research in supporting Department of Defense modeling and simulation at the IMAGE 2017 conference in Dayton, OH, 27-28 Jun. Under the paper and talk titled Demonstrating a Weather Simulation Federate for Distributed Mission Operations, we will discuss the case for a weather simulation federate that provides control to simulation operators and exercise controllers to adjust weather scenario content to better meet required impacts, training and analysis objectives. We demonstrate these ideas with a prototype federate called WxSim. These results provide insight and a starting point for significantly improving the representation of the natural environment in DoD simulations, and ultimately improving their value to analysis, training and mission rehearsal.
