1 README Dataset for “Mass loss of the Greenland ice sheet until the year 3000 under a sustained late-21st-century climate” 16 model experiments • hist: historical simulation 1990–2015. • ctrl_proj: constant-climate projection control experiment 2015–3001. • exp05–10, expa01–a03, expb01–b05: future-climate experiments 2015–3001 (see Table 1 of the paper). Zip archives • hist.zip, ctrl_proj_long.zip, exp05_long.zip, exp06_long.zip, …, expb05_long.zip: netCDF output files for the 16 experiments (one file for each variable). • run_specs_headers.zip SICOPOLIS run-specs headers for the 16 experiments. Scalar state variables lim – Total ice mass (kg) limnsw – Mass above floatation (kg) iareagr – Grounded ice area (m2) These variables are provided as yearly snapshots for the full years 2016–3001 [hist: 1991–2015]. Time variable: ‘time’. Scalar flux variables dlimdt – Total ice mass change (kg a−1) tendacabf – Total surface mass balance flux (kg a−1) tendlibmassbf – Total basal mass balance flux (kg a−1) tendlicalvf – Total calving flux (kg a−1) These variables are provided as yearly averages over the intervals bounded by the years 2015–3001 [hist: 1990–2015]. Time variables: ‘time’, ‘time_bnds’. 2D state variables lithk – Ice thickness (m) orog – Surface elevation (m) base – Ice base elevation (m) topg – Bedrock elevation (m) 2 xvelsurf – Surface velocity in x (m a−1) yvelsurf – Surface velocity in y (m a−1) zvelsurf – Surface velocity in z (m a−1) horvelsurf – Horizontal surface velocity (m a−1) xvelbase – Basal velocity in x (m a−1) yvelbase – Basal velocity in y (m a−1) zvelbase – Basal velocity in z (m a−1) horvelbase – Horizontal basal velocity (m a−1) xvelmean – Mean velocity in x (m a−1) yvelmean – Mean velocity in y (m a−1) horvelmean – Horizontal mean velocity (m a−1) litemptop – Surface temperature (K) litempbot – Basal temperature (K) strbasemag – Basal drag (Pa) sftgif – Land ice area fraction (–) These variables are provided as snapshots for the years 2020 (5) 2100 (25) 3000, 3001 [hist: yearly snapshots for 1991–2015]. Time variable: ‘time’. 2D flux variables acabf – Surface mass balance flux (kg m−2 a−1) libmassbf – Basal mass balance flux (kg m−2 a−1) licalvf – Calving flux (kg m−2 a−1) dlithkdt – Ice thickness imbalance (m a−1) hfgeoubed – Geothermal heat flux (W m−2) These variables are provided as averages over the intervals bounded by the years 2015 (5) 2100 (25) 3000, 3001 [hist: yearly averages bounded by 1990–2015]. Time variables: ‘time’, ‘time_bnds’. Notes • The variable names follow closely the ISMIP6 convention (e.g., Table A1 of https://tinyurl.com/ismip6-wiki-gris). However, years are used instead of seconds as the time unit (1 a = 31,556,926 s). • For further details, see the metadata in the netCDF files (e.g., by Linux command ‘ncdump –h’ or MATLAB command ‘ncdisp’) and the paper.
