Antarctic Ice Sheet Surface Elevation Change (SEC) for the ESA Antarctic CCI+ Phase-2 project
Abstract
Gridded Antarctic Ice Sheet Surface Elevation Change (SEC) products derived from cross-calibrated radar and laser satellite altimetry missions since 1991. Products are processed by the Centre for Polar Observation and Modelling (CPOM) as part of the Antarctic CCI+ Phase-2 project for the European Space Agency (ESA). The dataset includes multi-mission 5-year rates of surface elevation change (dH/dt), cumulative annual dH grids, single radar altimetry mission SEC products (ERS-1, ERS-2, ENVISAT, CryoSat-2, Sentinel-3A, Sentinel-3B), and an ICESat-2 laser altimetry SEC product. All gridded products are provided on a 5 km south polar stereographic grid (EPSG:3031).

| Data lineage: |
Surface elevation change products are derived from radar altimetry data acquired by ERS-1 (1991–1996), ERS-2 (1995–2003), ENVISAT (2002–2012), CryoSat-2 (2010–present), Sentinel-3A (2016–present), and Sentinel-3B (2018–present), and from laser altimetry data acquired by ICESat-2 (2018–present). Cross-calibration of radar altimetry missions was performed to produce consistent multi-mission records. Processing was carried out by CPOM. Products are provided on a 5 km south polar stereographic grid (EPSG:3031). Single-mission SEC products represent the full operational period of each mission. Multi-mission products combine all available radar altimetry missions. |
| Data Quality: |
Products include gridded uncertainty estimates alongside surface elevation change rates. Multi-mission products are derived from cross-calibrated radar altimetry data to ensure consistency across the record. Data are released as version 2 (v2) under the Antarctic CCI+ Phase-2 project.
