Standalone ecWAM wave model CY51R1 forced by corrected ERA5 hourly neutral 10m winds, air density, gustiness and sea ice fraction (1990-1999). Native grid is Tco799 (14km), 36 directions, 36 frequencies. Altimeter wave data assimilation,See Bidlot et al. 2026: Wave Hindcast for ERA6 Preparation and Training Data Driven Models. ECMWF Tech Memo, in preparation, Hourly output, many parameters. param=140098/140099/140100/140101/140102/140103/140104/140105/140112/140113/140114/140115/140116/140117/140118/140119/140120/140121/140122/140123/140124/140125/140126/140127/140128/140129/140131/140132/140133/140134/140207/140208/140209/140211/140212/140214/140215/140216/140217/140218/140219/140220/140221/140222/140223/140224/140225/140226/140227/140228/140229/140230/140231/140232/140233/140234/140235/140236/140237/140238/140239/140244/140245/140246/140247/140249/140252/140253/140254, See chapter 10 of https://www.ecmwf.int/en/elibrary/81629-ifs-documentation-cy49r1-part-v… and https://codes.ecmwf.int/grib/param-db/
