Short summary
This paper assesses the performance of the latest version (DT2021) of global gridded altimetry products distributed through the CMEMS and C3S Copernicus programs on the retrieval of sea level in the coastal zone of the European seas with respect to the previous DT2018 version. This comparison is made using an external independent dataset. DT2021 sea level products better solve the signal in the coastal band.
