Standalone ecWAM wave model CY50R1 with altimeter wave height assimilation forced by operational lwda 6-hourly stress equivalent neutral 10m winds, air density, gustiness and sea ice fraction AND surface currents from ORAS6 (2021-2026-02-03). Native grid is Tco1279 (9km), 36 directions, 36 frequencies, current refraction. See Bidlot et al. 2026: Wave Hindcast for ERA6 Preparation and Training Data Driven Models. ECMWF Tech Memo, in preparation, 6-hourly output, many parameters. param=140114/140115/140116/140117/140118/140119/140120/140132/140134/140218/140221/140222/140229/140230/140231/140232/140233/140244/140245/140246/140247/140249/151131/151132, See chapter 10 of https://www.ecmwf.int/en/elibrary/81629-ifs-documentation-cy49r1-part-v… and https://codes.ecmwf.int/grib/param-db/ !!!
