Creation of a Global UV-VIS-IR Ocean Background Model That is a Function of Time, Location and Sea State

Areté Associates will develop an “ocean terrain” model for use with standard Missile Defense Agency (MDA) radiation code to create high fidelity simulations over the ocean. Specifically, Areté will apply its Synthetic Ocean Scene Generator (SOSG) to create ocean surface radiance fields in the ultraviolet (UV), visible (VIS), and infrared (IR) wave bands, and couple them to the SHARC and MODTRAN Merged Code version 2 (SAMM2) radiation code. SOSG simulates ocean scenes of arbitrary geometry, incorporating nonlinear wave physics and accounting for water temperature and optical properties. The primary objectives of this Phase I effort are to interface SOSG with SAMM2, simulate ocean scenes over a broad range of scales, from local to global, and validate the simulations. Phase I activities will also include defining a sustainable architecture for MDA simulations and a plan for validation, both of which will be carried out in Phase II.
