Preliminary Study For Retrieval Of The Properties Of Marine Atmospheric Boundary Layer By SAR

The basic concepts of the Marine Atmospheric Boundary Layer (MABL) and the similarity theory are introduced in this study. The development and principle of Satellite-borne Synthetic Aperture Radar (SAR) are presented. The phenomena of MABL that can be detected by SAR are also preliminarily summarized.The methods reported by G. S. Young in 2000, are applied on sea surface SAR images featured by three dimensional convective cells. Then the following parameters are retrieved from SAR images: the characteristic wave length of three dimensional convective cell, the MABL depth, the vertical convective scale velocity, the surface buoyancy flux, Obukhov length and the stability correction factor for SAR derived sea surface wind speed.Retrieval of the parameters of MABL from SAR image is a frontier research area, there are no reports in china up to now.
