Abstract

Compact wave buoys are increasingly used to provide monitoring of coastal and oceanic conditions by measuring surface waves in real time. Due to their relatively compact size, they are generally not suited to measure wind directly. However, since the wave field is intrinsically coupled to the wind field, wave measurements can serve as a proxy observation of ocean surface winds. In this study, we use spectral wave observations to estimate wind speed and direction based on the assumption of a universal shape of the wave energy spectrum in the equilibrium range and the presence of a logarithmic wind speed profile above the ocean surface. The wind speed and direction were estimated between 2014..
