Dear colleagues,

Recently, our paper, “WAPOSAL: A Multi-Regional Wave Dataset from Satellite Altimetry for Significant Wave Height, Period Estimation, and Wave Power Density,” has been published on the Earth System Science Data platform as a preprint.

> Abstract. Accurate assessment of wave power density (WPD) is essential for marine renewable energy development and for validating numerical wave models, particularly in coastal and nearshore regions where in situ observations are sparse. This study...

We invite everyone interested to familiarize themselves with the paper and join the open discussion.
