Abstract:

The primary focus of this research is to integrate dynamical processes of wave and turbulence in the upper ocean surface boundary layer SBL into a physics-based computational capability for the time-dependent radiative transfer RT in the ocean. The combined capability we develop will provide direct forward predictions of the radiance distributions in the upper ocean. We aim to use this capability for understanding the basic features and dependencies of oceanic radiance on the wave environment, to provide guidance and cross-calibration for field measurements, and to validate and benchmark existing and new theories. As an ultimate goal, the proposed direct simulation also provides a framework, in conjunction with sensed radiance data, for the optimal reconstruction of salient features of the ocean surface and the above-water scene.
