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.
