The Stochastic Soaring Raptor Simulator (SSRS) is designed to predict movements of soaring raptors (such as golden eagles) with the goal of determining potential negative interactions between soaring raptors and wind turbines. SSRS uses a stochastic agent-based model for simulating a large number of wind- riding eagle paths at turbine-scale resolution using the atmospheric conditions at a specific time and the ground features (altitude, slope, aspect) at a particular site. SSRS can be applied to any rectangular region within the United States without the need for any eagle-centric or atmosphere-related data collection efforts, using only publicly available data sources. SSRS outputs a presence density map, which could be used to design tailored collision-mitigation measures or for future plant siting.
