Description

===============================================================
Future freshwater fluxes from the Antarctic ice sheet (dataset)
===============================================================

-----------------------
INTRODUCTION
-----------------------

This dataset contains historically-calibrated projections of Antarctic freshwater fluxes (ice-shelf melting, iceberg calving, and surface meltwater runoff) under low and very-high emission scenarios for 27 drainage basins and 5 ocean sectors until 2300.

We perform, with the Kori-ULB ice-sheet model v0.91, an ensemble of historically-calibrated simulations of the Antarctic ice sheet between 1990 and 2300 forced by atmospheric and oceanic projections inferred from a subset of models from the sixth phase of the Coupled Model Intercomparison Project (CMIP6) under low- and very high-emission scenarios. 

We refer to the associated manuscript for more information on the applied methodology.

PROVIDED DATA
-------------------------

  • 'SSP126_FWF_1990_2300_ZwallyBasins.nc' and 'SSP585_FWF_1990_2300_ZwallyBasins.nc' each contain yearly timeseries of the [5 25 50 75 95] percentiles for the calibrated probabilistic projections of Antarctic net mass balance, surface mass balance, sub-shelf melt, and calving fluxes (in Gt/yr) for each of the 27 Zwally drainage basins (see http://imbie.org/imbie-2016/drainage-basins/) under a SSP1-2.6 and SSP5-8.5 scenario, respectively.

  • 'SSP126_FWF_1990_2300_OceanSectors.nc' and 'SSP585_FWF_1990_2300_OceanSectors.nc' each contain yearly timeseries of the [5 25 50 75 95] percentiles for the calibrated probabilistic projections of Antarctic net mass balance, surface mass balance, sub-shelf melt, and calving fluxes (in Gt/yr) for each of the 5 ocean sectors (Weddell Sea, Indian Ocean, western Pacific Ocean, Ross Sea, Amundsen & Bellingshausen Sea) under a SSP1-2.6 and SSP5-8.5 scenario, respectively.

  • 'SSP126_FWF_1990_2300_AIS.nc' and 'SSP585_FWF_1990_2300_AIS.nc' each contain yearly timeseries of the [5 25 50 75 95] percentiles for the calibrated probabilistic projections of Antarctic net mass balance, surface meltwater runoff, sub-shelf melt, and calving fluxes (in Gt/yr) for the Antarctic Ice Sheet under a SSP1-2.6 and SSP5-8.5 scenario, respectively.
