Global wave hindcasts are developed using the third generation spectral wave model WAVEWATCH III with the observation-based source terms (ST6) and a hybrid rectilinear-curvilinear, irregular-regular-irregular grid system (approximately at (Formula presented.)). Three distinct global hindcasts are produced: (a) a long-term hindcast (1979–2019) forced by the ERA5 conventional winds (Formula presented.) and (b) two short-term hindcasts (2011–2019) driven by the NCEP climate forecast system (CFS)v2 (Formula presented.) and the ERA5 neutral winds (Formula presented.), respectively. The input field for ice is sourced from the Ocean and Sea Ice Satellite Application Facility (OSI SAF) sea-ice conce..View full abstract

This work relies heavily on the reanalysis, satellite, and buoy data sets that are freely accessible in the public domain. The authors appreciate all the operational centers, universities, and institutes who have provided these invaluable data, including ECWMF, NCEP, OSI SAF, AODN, ESA Sea State CCI, ESA SST CCI, Ifremer/Los, NODC, CDIP, MEDS, KMA, KHOA, KORS, PNBOIA, OOI, and MetOcean Solutions. The authors are grateful to Julia Kaiser and Nelson Violante-Carvalho (Federal University of Rio de Janeiro) for discussion about the Brazilian buoy data. The authors thank David W. Wang from the U.S. Naval Research Laboratory for his comments on an earlier version of this manuscript. The authors are also indebted to Dr. Alberto Meucci (University of Melbourne) for valuable discussions on the wave hindcasts. Q. Liu and A.V. Babanin acknowledge the financial supports from the DISI Australia-China Centre through Grant ACSRF48199 and from the Office of Naval Research Global (Grant Number: N62909-20-1-2080). The authors are grateful for constructive comments from the editor and three anonymous reviewers. This study and the original submission were completed while the first author was a postdoctoral fellow at University of Melbourne. The ST6 wave hindcasts are archived at the Mediaflux platform, a data storage and management service kindly supported by the Research Computing Services of the University of Melbourne.
