'''Short description:''' Antarctic sea ice displacement during winter from medium resolution sensors since 2002 '''DOI (product) :''' https://doi.org/10.48670/moi-00120

Arctic sea ice drift datasets at 3, 6 and 30 day lags during winter. The Arctic low resolution sea ice drift products provided from IFREMER have a 62.5 km grid resolution for ASCAT, QuikSCAT, CFOSAT and SSM/I data. AMSR sea ice drift datasets have a 31.25 km grid resolution. These products are delivered as daily products at 3, 6 and 30 days for the cold season extended at fall and spring : from September until May, it is updated on a monthly basis. The data are « merged » product from radiometer and scatterometer : * QuikSCAT, ASCAT observations for over 20 years * QuikSCAT, ASCAT & SSM/I merged products for over 20 years * AMSR observations for over 20 years * SSM/I 85 GHz V & H Merged product (1992-1999) * CFOSAT observations The exhaustive list can be found through the “Data access” link from the menu.

'''This product has been archived''' For operationnal and online products, please visit https://marine.copernicus.eu '''Short description''' The Operational Mercator global ocean analysis and forecast system at 1/12 degree is providing 10 days of 3D global ocean forecasts updated daily. The time series is aggregated in time in order to reach a two full year’s time series sliding window. This product includes daily and monthly mean files of temperature, salinity, currents, sea level, mixed layer depth and ice parameters from the top to the bottom over the global ocean. It also includes hourly mean surface fields for sea level height, temperature and currents. The global ocean output files are displayed with a 1/12 degree horizontal resolution with regular longitude/latitude equirectangular projection. 50 vertical levels are ranging from 0 to 5500 meters. This product also delivers a special dataset for surface current which also includes wave and tidal drift called SMOC (Surface merged Ocean Current).

'''Short description:''' The GLORYS12V1 product is the CMEMS global ocean eddy-resolving (1/12° horizontal resolution, 50 vertical levels) reanalysis covering the altimetry (1993 onward). It is based largely on the current real-time global forecasting CMEMS system. The model component is the NEMO platform driven at surface by ECMWF ERA-Interim then ERA5 reanalyses for recent years. Observations are assimilated by means of a reduced-order Kalman filter. Along track altimeter data (Sea Level Anomaly), Satellite Sea Surface Temperature, Sea Ice Concentration and In situ Temperature and Salinity vertical Profiles are jointly assimilated. Moreover, a 3D-VAR scheme provides a correction for the slowly-evolving large-scale biases in temperature and salinity. This product includes daily and monthly mean files for temperature, salinity, currents, sea level, mixed layer depth and ice parameters from the top to the bottom. The global ocean output files are displayed on a standard regular grid at 1/12° (approximatively 8 km) and on 50 standard levels. '''DOI (product) :''' https://doi.org/10.48670/moi-00021
