The period 2015-2021 has diversified the portfolio of modeling products dedicated to the Arctic. The addition of waves, tides and ocean carbon variables satisfy more adequately the users in the industry, academia and public sectors. Many validation metrics have also been introduced, providing more intuitive measures of the quality of the forecast. The resolution of several products has increased, particularly the horizontal resolution of the sea ice forecasts thanks to a stand-alone sea ice model based on a novel rheology. At the end of the Copernicus 1 period, physical and biogeochemical products come from different configurations of the TOPAZ model system, plus a stand-alone sea ice forecast from the neXtSIM model and forecast and hindcast from an Arctic configuration of the WAM wave model.
