Arctic sea ice freeboard and thickness from data of the European radar altimeter CryoSat-2 is generated by the Alfred Wegener Institute (AWI) in the winter month (October-April). The resulting data products are publicly available under a  Creative Commons Attribution 4.0 International (CC BY 4.0) license. Please read the documentation below for data access and formats.

This service does not intent to be an operational data dissimination service. Interruptions of data provision might occur at any time. We stress the fact that the interpretation of CryoSat-2 radar signals over sea ice and the uncertainties of freeboard retrieval and conversion into sea ice thickness are still an active field of research. This product shall therefore be used as a tool for the scientific community to enable further development of sea ice thickness retrieval algorithms from radar altimetry.

It is however our aim, to regurlary revise and improve the sea-ice processing chain for CryoSat-2 data and provide incremental update at the start of each Arctic winter season in October.

We encourage users to give feedback (info(at)meereisportal.de) for further improvements of the AWI CryoSat-2 sea ice product.
