Abstract:

The ultimate goal is to develop direct simulationphysics-based forward and inverse capabilities for radiance prediction in a dynamic ocean environment. This direct simulation-based model will include and integrate all of the relevant dynamical processes in the upper ocean surface boundary layer into a physics-based computational prediction capability for the time-dependent radiative transport. Objectives To include and integrate relevant dynamical processes in the upper ocean surface boundary layer SBL into a physics-based computational prediction and inverse capability for the time-dependent radiative transport Develop direct simulation of upper ocean hydrodynamic processes and forward prediction of radiative transfer Obtain understanding, modeling and parameterizations of dependencies of oceanic radiance on the surface wave environment Provide guidance for field measurements and obtain cross validations and calibrations with direct simulations and modeling Provide a framework for inverse modeling and reconstruction of ocean surface and above water features based on sensed underwater radiance data To reach these objectives, we had and would continue to have a close collaboration with Professor Lian Shen of the Johns Hopkins University JHU on the modeling of free surface turbulence roughness.
