The Reconstructed GRACE TWSA dataset for China

A
long-term reconstructed TWSA dataset for the land area of China (RECTWS-CHN) based
on the GRACE observations. In
the RECTWS-CHN dataset, two approaches combined with a spatially moving window
structure are used to reconstruct the GRACE-based TWSA observations back to
1950s over the land area of China respectively. The two approaches are the Random
Forest (RF) and the linear regression model (LR).

本数据集为基于重力恢复与气候实验卫星（GRACE, Gravity Recovery and Climate Experiment）观测数据构建的中国陆域长期陆地水储量异常（TWSA, Terrestrial Water Storage Anomaly）重建数据集RECTWS-CHN。在RECTWS-CHN数据集中，研究采用两种结合空间移动窗口结构的方法，分别针对中国陆域将基于GRACE的陆地水储量异常观测序列回溯重建至20世纪50年代。两种方法分别为随机森林（RF, Random Forest）与线性回归模型（LR, Linear Regression）。
