The Euro-Mediterranean Center on Climate Change Global Ocean Physical Reanalysis (CGOLRS) v7 is a homogeneous three-dimensional reconstruction of the global ocean state over the last decades constrained by observations. It spans the altimeter era (1993-2019) and is produced by the global ocean circulation model NEMO coupled with the LIM2 sea-ice model with an overall working resolution of 1/4°. The data assimilation system consists of a three-dimensional variational scheme (called OceanVar) capable of assimilating all in-situ observations along with altimetry data. The data assimilation system is performed every 7 days, using a 10-day assimilation time-window. On-line surface nudging schemes, during model integration, assimilate satellite observations of sea surface temperature, sea ice concentration and sea ice thickness. An older version (v5) of the same Reanalysis family but spanning more years 1980-2014 is available at doi:10.1594/PANGAEA.857995. In the v7 we increased the vertical resolution (75 depth ... : This dataset has been produced by the Euro-Mediterranean Center on Climate Change (CMCC) in the context of the Copernicus Marine Environment and Monitoring Service (CMEMS). The activities leading to these results have been contracted by Mercator Ocean International that implements CMEMS as part of the Copernicus Programme. ...
