High Resolution Surface Characterization from Marine Radar Measurements

Abstract

The long term goal of this proposed project is to improve our understanding of how radar-based measurements from shipborne or spaceborne sensors can be used to represent the phase-resolved surface wave field (PRSWF) for driving highly-nonlinear numerical surface wave models that predict the evolution of the PRSWF. The specific scientific objectives of this study, to be carried out in collaboration with the Hi-Res DRI investigators, are: 1) To compare wind stress measurements from the ASIS buoys during the SW06 experiment with aerodynamic roughness parameterizations from Donelan et al. (2004) and Powell et al. (2003). 2) To compare array measurements of surface elevation data from ASIS with surface elevation maps from the inverted WaMoS radar data. Determine error characteristics as a function of sea state and wave field complexity. 3) Apply new SAR technology to estimate small scale wind and surface roughness fields and surface elevation maps from high resolution SAR images.
