Adaptive Remote Sensing of the Island Arc Turbulent Eddy Regional Exchange (ARCTERX)
Abstract
This proposal in response to the DRI: Island Arc Turbulent Eddy Regional Exchange requests funding to implement a suite of advanced and adaptive remote sensing techniques for characterizing conditions of the North Equatorial Current between the Mariana Island Arc and the Strait of Luzon. A suite of satellite-based geophysical data products will be generated both at synoptic scales over the Nor th Pacific Ocean and at meso and sub-meso scales for tracking in-situ instrumentation. The satellite data include both publicly avai lable data sets and commercial data sets. The latter will be specifically tasked for events and emerging situations. The synergy of these data sets provide products across the range of scales addressed by this DRI. The adaptive approach to satellite collections wi ll allow data products to be generated to provide improved boundary conditions for adaptive grids of the numerical modeling of small -scale ocean processes including meanders, rings, vortices, and filaments. The Center for Southeastern Tropical Advanced Remote Sens ing (CSTARS), will work to advance techniques of synthetic aperture radar (SAR) interferometry, radar-grammetry, surface characteriz ation and coherent and amplitude-based change detection based on SAR intensity images and optical images, as well as SAR-based winds and waves, in a synergistic approach to generate high-resolution maps of a variety of geophysical parameters of interest. Furthermo re, maps of SAR-derived winds and wave heights will be provided repeatedly and in near-real time over areas actively monitored by au tonomous instrument platforms. This variety of geophysical parameters resulting from the combined analysis of spaceborne radar and o ptical data will provide an unprecedented amount of information on the characteristics of small-scale fronts and eddies at high spat ial resolution and accuracy.
