"A 25-year reanalysis [ 01/01/1993 - 31/12/2019 ] of the physical and sea ice parameters of the global ocean. There are daily and monthly averages over the whole water column and hourly averages for surface temperature and surface currents. The numerical data are divided into different files that contain 3D information on potential temperature, salinity and currents and 2D information on sea surface level, potential bottom temperature, mixed layer thickness, sea ice thickness, sea ice fraction and sea ice velocities. These data are distributed on a native 1/12° grid (~9.3km at the equator)."
