'''Short description:'''

The GLO-CPL weakly coupled ocean-atmosphere data assimilation and forecast system is used to provide 10 days of 3D global ocean forecasts, at ¼ degree, updated daily. The system uses a Met Office Unified Model v10.6 atmosphere configuration (at ~ 40 km resolution) coupled hourly to a NEMO v3.4 ocean configuration and to the multi-thickness-category sea ice model CICE v4.1 (both on the ORCA025 grid). Atmosphere and ocean data assimilation are using 4D-var and 3D-var respectively. Ocean observations assimilated include satellite SST data, in-situ SSTs from moored buoys, drifting buoys and ships, sea level anomaly observations from CMEMS, sub-surface temperature and salinity profiles (including Argo, moored buoys, marine mammals, and gliders) and sea ice concentration (SSMIS data provided by OSI-SAF as a daily gridded product). The ocean forecast and analysis is provided daily, along with an updated analysis a day later which makes use of more observations. This product includes daily mean files of temperature, salinity, currents, sea level, mixed layer depth and sea ice parameters (and hourly instantaneous sea surface temperature, sea surface height and surface currents). The product files are provided with 1/4o horizontal resolution on a regular lat/lon projection and with 43 vertical levels ranging from 0 to 5500 meters.
