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).
