The relative sea level induced by ice sheets from SAGEA-fluid

This is dataset is the relative sea level distribution induced by the ice sheets change (Greenland and Antarctica, respectively) from SAGEA-fluid. It can be used to verify the self-attraction and loading induced by ice sheets.For more detail, the input data to get the dataset is from GRACE (CSR RL06), and the time period is the GRACE period, i.e., 2002-2017. The post-processing methods include replacement of low-degree terms (degree-1, C20 and C30), removal of GIA using ICE-6GD, subtraction of the mean field and filtering with DDK3.

本数据集为基于SAGEA-fluid模型得到的、由格陵兰冰盖与南极冰盖分别变化引发的相对海平面分布数据，可用于验证冰盖引发的自吸引与负荷效应。如需获取更多细节，本数据集的输入数据来源于重力恢复与气候实验（Gravity Recovery and Climate Experiment, GRACE）的CSR RL06产品，其时间跨度对应GRACE观测时段，即2002年至2017年。后处理方法包括替换低阶球谐项（阶数1、C20与C30）、借助ICE-6GD模型移除冰川均衡调整（Glacial Isostatic Adjustment, GIA）信号、扣除平均场以及采用DDK3滤波进行处理。
