Several sea ice concentration data sets have been prepared as shown in the table below. They are based on SMMR, SSM/I and SSMIS  (1929-2015) , AMSR-E (2002-2011) and AMSR2 (2013-2015).

Version 2.0 of the Sea Ice Concentration (SIC) Climate Data Record data sets from AMSR-E and AMSR2 (2002-2017) were released on 28 February 2018. The SIC Climate Data Record data set from SMMR, SSMI and SSMIS (1979 – 2015) have previously been released.   The data sets are available at

http://icdc.cen.uni-hamburg.de/1/projekte/esa-cci-sea-ice-ecv0.html,

http://osisaf.met.no/p/ice/index.html#conc-reproc-v2, and in the

CCI Data Portal

Ice thickness data sets

Sea ice thickness and freeboard from Arctic and Antarctic  are provided from Envisat RA-2 (2002-2012) and Cryosat-2 SIRAL2 (2010 - 2017).

Version 2.0 of the sea-ice thickness dataset was released on 20 June 2018 by AWI. 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.
