Data Content & Format
Distributed data processing levels are the daily trajectory summary (l2p) and weekly/monthly gridded data (l3c).

Version History
Sea ice data products are continuosly updated. The history of existing products is listed below.
Sea ice products are continuously updated to include scientific and technical improvements. We aim for a yearly update cycle for the AWI CryoSat-2 sea-ice data, which is implemented at the start of the Arctic winter season on Oct. 1st. An update of the algorithm includes a re-processing of the full CryoSat-2 data record. Each update contains algorithm evolutions (changes of the processing evolutions) and system evolutions (changes of the code or input data sets).
