New results have been obtained from both the K/sub u/- band scatterometer and from the in-situ, large area estimates of surface wind stress and direction during the SWADE 1991 experiment. These results address the accuracy of the K/sub u/-band model function for estimating the magnitude of the friction velocity, and the ability of the azimuthal scatterometer data to estimate the wind direction. They demonstrate an excellent accuracy for estimating friction velocity magnitude. But they show the potential for frequent errors in estimating wind direction because of small upwind/downwind differences in the radar cross section at the lower incidence angles; however accuracy improves at the higher incidence angles. These results provide useful information in the development of NSCAT/ADEOS algorithms.
