A relation between the wind friction velocity and the sea surface microwave scattering

open access: yesCiencias Marinas, 2002
 A simple recursive algorithm for the estimation of the friction velocity as a function of the air-sea temperature difference and the wind speed measured at 10-m height above the sea surface, without needing of drag coefficient, is presented.
