This project deals with the production of level 2, level 3 and level 4 products making use of the technique of swath interferometry applied to SARIn mode CryoSat data to make inference about the state of the Antarctic and Greenland Ice Sheets in a period of rapid changes and increased contribution to sea level.

It follows from two successful experimental project (CryoTop and Glitter) that developed and demonstrated the impact that swath altimetry can make on the study of the cryosphere and its interaction with climate.
