The EOLIS products exploit CryoSat’s SARIn mode and the novel swath processing technique to deliver increased spatial and temporal coverage of time-dependent elevation over land ice, a critical metric for tracking ice mass trends.


The data provided by this project aims to:

• Target a wider community of scientific end–users, outside the usual altimetry expert groups (e.g. modellers, Climate/Operational services);
• Be high level (~L2+/CEOS-ARD), user-friendly and simple, including no more than 6-7 parameters including uncertainty estimates;
• Quickly evolve and reflect the most recent scientific outcomes, being generated alongside CryoSat’s core Payload Data Ground Segment (PDGS) products;
• Be easily accessible from a user-friendly interface.
