Surveying sea surface effect in satellite altimeter-derived wind speed

To improve sea surface wind speed in coastal regions, we used nadir satellite altimeter measurements in thePersian Gulf and Arabian Sea. With combining normalized radar cross section for two bands of satellite altimetermeasurements and significant wave height suggested the method to obtain “true” sea surface wind speed. In thecoastal regions, we used a dimensionless significant wave height to gain empirical dependency to fetch-limitedwind wave development. In this research, normalized radar cross section is simulated by using inverse wave ageand fetch laws. As established this method helps to refine altimeter measurements of sea surface wind in thecoastal regions.
