CCI Sea Ice Dataset Release (Sea Ice Thickness v2.0)

The CCI Sea Ice team is pleased to announce the release of their updated version of the sea-ice thickness dataset (v2.0). This dataset includes observations, made by two radar altimeter missions - Envisat and CryoSat-2, on polar Winters between October 2002 and April 2017. This dataset, in comparison to the previous dataset (v1.0), provides a number improvements which include improved sea-ice thickness retrievals from Envisat data, an experimental data record in the southern hemisphere, the delivery of trajectory-based Level 2 products and the availability of freeboard data in Level 2 and 3 products. 

The sea-ice thickness data is open and publicly available via the CCI Data Portal.
