Enhanced Global Sea Ice Monitoring

The European Space Agency's Climate Change Initiative has released a new high-resolution sea-ice concentration data record covering 30 years (1991-2020) of sea-ice concentration in higher resolution, providing new insights of sea ice concentration across the globe. The data is processed from microwave imagery and Numerical Weather Prediction data through a dedicated algorithm developed by the CCI Sea Ice team. The data were then validated using data from the Copernicus Sentinel-1 radar mission which provides all-weather sea-ice mapping capabilities. The new dataset will help improve model predictions and understanding of Arctic dynamics.
