Data for: The changing mass of the Antarctic Ice Sheet during ENSO-dominated periods in the GRACE era (2002–2022)
Data pertain to the analysis of Antarctic Ice Sheet (AIS) mass variability during different ENSO phases, using GRACE‑observed mass changes and modelled surface mass balance from RACMO2.4p1 over the period 2002–2022, together with associated atmospheric circulation patterns. The gridded datasets include derived quantities from the regression analyses for the defined ENSO periods and AIS mass‑change trends, provided in NetCDF format, along with the accompanying MATLAB code.

- Statement
- The GRACE data used is available at https://gravis.gfz.de/ais (last access: 1 March 2025). The ERA5 reanalysis data used in the atmospheric linkage to ice mass variation are publicly available from https://cds.climate.copernicus.eu/ (last access: 1 March 2025). The station-derived SAM index from Marshall (2003) are available at http://www.nerc-bas.ac.uk/icd/gjma/sam.html (last access: 1 March 2025). The Niño3.4 index are publicly available from https://psl.noaa.gov/data/timeseries/month/Nino34/ (last access: 1 March 2025). RACMO2.4p1 model SMB output can be accessed at https://doi.org/10.5281/zenodo.14217232 (van Dalum et al., 2024a). AIS mass‑variability datasets were derived using regressions for different ENSO periods, based on GRACE‑observed mass changes and modelled surface mass balance from RACMO2.4p1 over 2002–2022.
