GRACE time series of Antarctic Ice Sheet mass change 2002-2021, and related climate datasets

Data pertain to analysis of GRACE time series of mass change in both gridded and basin format. The GRACE data are based on the COST-G solution obtained from http://gravis.gfz-potsdam.de/home. Both 50km regular gridded data and basin-level time series are included, as well as the SAM and ENSO climate indices on which the regressions were based. The gridded datasets provided here include derived quantities from the regressions such as trends, uncertainties, and regression coefficients in NetCDF format.

本数据集涉及格网与流域两种格式的重力恢复与气候实验（GRACE）质量变化时间序列分析。本次所用GRACE数据源自http://gravis.gfz-potsdam.de/home获取的COST-G解算结果。数据集涵盖50公里规则格网数据、流域尺度时间序列，以及回归分析依托的南半球环状模（SAM，Southern Annular Mode）与厄尔尼诺-南方涛动（ENSO，El Niño-Southern Oscillation）气候指数。本次提供的格网数据集包含回归分析所得的衍生参数，包括变化趋势、不确定性估计值与回归系数，数据格式为网络通用数据格式（NetCDF）。
