The CryoTEMPO-EOLIS dataset, developed to monitor elevation change across the world’s glaciers, ice sheets and ice shelves using swath radar altimetry from ESA’s CryoSat-2 satellite, has reached a new milestone with the release of Baseline 3.
Products based on Baseline 3 are now available from January 2026 onwards for all regions, including glaciers, ice sheets and ice shelves. In the coming months, the entire CryoSat-2 record will also be reprocessed back to July 2010, providing a consistent long-term dataset.
CryoTEMPO-EOLIS Baseline 3 introduces several improvements:
- Increased data density and spatial coverage in both the point and gridded products, particularly in complex terrain such as mountain glaciers and ice sheet margins
- Improved measurement quality, resulting in more reliable elevation estimates
- More robust uncertainty estimates using a new error metric
- New variables:
- Elevation change from a reference period, enabling users to visualise height change patterns and quantify volume change (gridded product only)
- Elevation difference from a reference Digital Elevation Model (DEM) (point and gridded products)
