Version 2.0 of the sea-ice thickness dataset was released on 20 June 2018 by AWI. This dataset includes observations, made by the two radar altimeter missions, Envisat and CryoSat-2, for both Arctic and Antarctic from October 2002 to April 2017. This dataset, in comparison to the previous dataset (v1.0), provides a number of 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 are open and available vis the CCI Data Portal (http://cci.esa.int/data).
