ABSTRACT
The knowledge of wave conditions, either as climatology or short-term forecast, is critical for all human activities at sea, including shipping, fishing, oil extraction, naval operation and designs. Efforts have been made in the past to produce consistent sets of wave data that could be used to establish reliable wave conditions for different locations and to obtain assessments of the expected extreme and a long term trends. At the same time, the operational wave forecasts have improved substantially over the last two decades, as well as data assimilation and computational wave modelling capacity. Two different and broadly used wind-wave data sets are compared in this paper.
