Air-Sea Fluxes from Synthetic Aperture Radar
Abstract
My long-term goal is the testing and refinement of a Monin-Obukhov and mixed-layer similarity-based method for the extraction of marine atmospheric boundary layer turbulence statistics from synthetic aperture radar (SAR)-derived wind speed imagery of the sea surface (first described in Young et al. (2000) and hereafter referred to as the SAR method). A plethora of SAR data is available from the Johns Hopkins University Applied Physics Laboratory (JHU/APL) in conjunction with the National Oceanic and Atmospheric Administration (NOAA) Storm Watch / Alaska SAR demonstration. In addition, my research has transitioned from sole-source Office of Naval Research (ONR) funding to a cost-share between ONR and the National Aeronautics and Space Administration (NASA). My collaborators on my NASA grant are Pierre Mourad, Ralph Foster, and Matt Wyant of the University of Washington Applied Physics Laboratory (UW/APL). We have begun testing the SAR method on wind images of the Tropical Atmosphere-Ocean buoy array area as well as on wind images corresponding to SHOWEX. Before this testing can proceed in earnest, we must address the following obstacle: Wind speeds statistics generated from identical SAR imagery by different parties can differ greatly. I will discuss this issue further in the Results section of this document.
