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.

Sea ice thickness information from CryoSat-2 is available from two data streams

  1. near-real time (nrt) data with a delay of 2 days
  2. reprocessed data with a delay of 33 days
