This data set includesthe materials required to reproduce the figures and tables presented in the study: "Higher Antarctic ice sheet accumulation and surface melt rates revealed at 2 km resolution". The data consist of: ASCII files: SMB-ANT-Sectors-1979-2021-RACMO2.3p2-ERA5-2km.txt : time series of Antarctic sector-integrated annual SMB (Gt per year) from ERA5-forced RACMO2.3p2 at 27 km, statistically downscaled to 2 km resolution (1979-2021). Melt-ANT-Sectors-1979-2021-RACMO2.3p2-ERA5-2km.txt: time series of Antarctic sector-integrated annual surface melt(Gt per year) from ERA5-forced RACMO2.3p2 at 27 km, statistically downscaled to 2 km resolution (1979-2021). Melt-ANT-Sectors-1950-2014-RACMO2.3p2-CESM2-HIST-2km.txt: time series of Antarctic sector-integrated annual surface meltfrom CESM2-forced RACMO2.3p2 historical reconstruction (HIST), statistically downscaled to 2 km resolution (1950-2014). Melt-ANT-Sectors-2015-2099-RACMO2.3p2-CESM2-SSP126-2km.txt: time series of Antarctic sector-integrated annual surface meltfrom CESM2-forced RACMO2.3p2 SSP1-2.6 projection (SSP126), statistically downscaled to 2 km resolution (2015-2099). Melt-ANT-Sectors-2015-2099-RACMO2.3p2-CESM2-SSP245-2km.txt: time series of Antarctic sector-integrated annual surface meltfrom CESM2-forced RACMO2.3p2 SSP2-4.5 projection (SSP245), statistically downscaled to 2 km resolution (2015-2099). Melt-ANT-Sectors-2015-2099-RACMO2.3p2-CESM2-SSP585-2km.txt: time series of Antarctic sector-integrated annual surface meltfrom CESM2-forced RACMO2.3p2 SSP5-8.5 projection (SSP585), statistically downscaled to 2 km resolution (2015-2099). Antarctic sectors include the Antarctic Peninsula (APIS), the West Antarctic ice sheet (WAIS), the East Antarctic ice sheet (EAIS), the grounded Antarctic ice sheet (AIS), the floating ice shelves (Ice shelves), and the whole of Antarctica (ANT) including both the AIS and Ice shelves. The APIS, WAIS, EAIS and AIS sectors include land ice from neighbouring Antarctic islands. Netcdf files: ...
