 This paper proposes a method for retrieving friction velocity and aerodynamic drag coefficients using C-band synthetic aperture radar, SAR, observations from Sentinel-1. The dataset included 14 SAR images taken during six hurricane scenes, which were compared with step-frequency microwave radiometer, SF measurements. The authors then developed a relationship between the ocean's surface emissivity, surface friction velocity, aerodynamic drag coefficient, and surface wind speed, which was further validated by comparing their results with those of H-14E and MS-1A. Finally, they applied their method to retrieve these parameters from the Hurricane Maria SAR image, September 23, 2017, showing that the proposed method is reliable and accurate.
