摘要

一项最新研究引入了一种新颖的深度学习方法，利用多变量时间序列图神经网络（MTGNN）重建南美的陆地水储存（TWS）异常，使用的数据来自1940年至2002年的GRACE卫星任务。该创新方法在重建性能上显著优于传统技术，达到更高的相关性指标，同时所需的预测因子显著减少。这项研究的影响可能增强我们对水储存动态的理解，并改善该地区的资源管理。

A recent study has introduced a novel deep learning approach that utilizes a multi-variate time series graph neural network (MTGNN) to reconstruct terrestrial water storage (TWS) anomalies in South America, using data from the GRACE satellite missions spanning from 1940 to 2002.
