Future freshwater fluxes from the Antarctic ice sheet

===============================================================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.===============================================================南极冰盖未来淡水通量（数据集）=============================================================== -----------------------引言----------------------- 本数据集收录了针对27个流域与5个大洋分区，在低排放与极高排放情景下至2300年的南极淡水通量（含冰架融化、冰山崩解与地表融水径流）的历史校准预测结果。 本研究采用Kori-ULB冰盖模型v0.91版本，开展了1990年至2300年间南极冰盖的历史校准集合模拟，模拟强迫场取自耦合模式比较计划第六阶段（Coupled Model Intercomparison Project, CMIP6）部分模式输出的大气与海洋预测数据，涵盖低排放与极高排放两类情景。 更多关于所采用方法的细节，请参阅相关学术论文。 -------------------------提供的数据------------------------- `SSP126_FWF_1990_2300_ZwallyBasins.nc`与`SSP585_FWF_1990_2300_ZwallyBasins.nc`分别对应SSP1-2.6与SSP5-8.5情景，二者均包含27个Zwally流域（详见http://imbie.org/imbie-2016/drainage-basins/）的南极净质量平衡、表面质量平衡、冰架下融化与冰山崩解通量（单位：Gt/yr）的校准概率预测结果逐年时间序列，包含[5、25、50、75、95]百分位数。 `SSP126_FWF_1990_2300_OceanSectors.nc`与`SSP585_FWF_1990_2300_OceanSectors.nc`分别对应SSP1-2.6与SSP5-8.5情景，二者均包含5个大洋分区（威德尔海、印度洋、西太平洋、罗斯海、阿蒙森海与别林斯高晋海）的上述四类通量的校准概率预测结果逐年时间序列，包含[5、25、50、75、95]百分位数。 `SSP126_FWF_1990_2300_AIS.nc`与`SSP585_FWF_1990_2300_AIS.nc`分别对应SSP1-2.6与SSP5-8.5情景，二者均包含南极冰盖整体的南极净质量平衡、地表融水径流、冰架下融化与冰山崩解通量（单位：Gt/yr）的校准概率预测结果逐年时间序列，包含[5、25、50、75、95]百分位数。
