图神经网络重建历史储水量数据

研究人员开发了一种使用时空图神经网络(MTGNN)重建历史陆地储水量(TWS)数据的新方法。该深度学习模型从气象强迫数据中学习,生成可追溯至1940年的月度TWS异常值,从而扩展了卫星记录。该方法表现强劲,在网格单元和流域尺度上均实现了高相关性,并能重现厄尔尼诺和拉尼娜等重大气候事件。与现有重建技术相比,基于图的模型具有竞争力,同时需要更少的预测因子,并揭示了所有测试模型在干旱地区普遍存在的弱点。 AI

影响 增强了历史气候数据的可用性,可能改善气候建模和水资源管理。

    利用时空图神经网络重建GRACE陆地储水:南美洲应用

    arXiv:2606.23833v1 Announce Type: new Abstract: Terrestrial water storage (TWS) integrates snow, soil moisture, surface water, and groundwater and is a key indicator of how climate variability and human activity reshape the global water cycle. The GRACE and GRACE-FO satellite mis…
