The CryoTEMPO-EOLIS data products
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.
The following tables indicate the temporal coverage of products. Further Baseline 2 data will be available following the full reprocessing of all regions - when this is available for download, these tables will be updated.

- 1.1 - Greenland and Antarctic Ice Sheets.
- 1.2 - Addition of the Mountain Glacier regions.
- 2.0 - Major Updates:
- Improvements to phase model correction, waveform filtering and uncertainty calibration across all regions.
- Improvements to gridding methods used over Antarctica and Greenland. Additionally, inclusion of gridded uncertainties for these products for the first time.
- The use of RGI 7 glacier masks in all mountain glacier regions.
The product handbook acts as a user guide and contains high level algorithm descriptions as well as an overview of file structure:
