重力恢复和气候实验（GRACE）任务提供陆地储水量的时空变化测量，这可能会改善陆地表面模型（LSMs）的模拟结果。我们表明，最近在动态生态系统中的组织碳和水文（ORCHIDEE） LSM中开发的转移方案显着改善了模拟的陆地水储存。在大型热带河流流域，不考虑转移方案的模式结果提供的储水量幅度明显小于GRACE观测到的。包括考虑河流系统和含水层在向海洋转移过程中储存的水的转移方案，可以预测与GRACE观测相媲美的陆地储水量。在亚马逊河、刚果河、长江、恒河、雅鲁藏布江和湄公河等大型流域，储水量的季节性变化约有一半是储存在含水层中的。
The Gravity Recovery and Climate Experiment (GRACE) mission provides measurements of spatiotemporal change in land water storage that may improve simulation results of land surface models (LSMs). We show that a transfer scheme recently developed within the Organising Carbon and Hydrology in Dynamic Ecosystems (ORCHIDEE) LSM significantly improves the simulated land water storage. Over large tropical rivers basins, model results without the transfer scheme provide significantly smaller amplitudes of water storage than observed by GRACE. Including the transfer scheme that accounts for water stored in the river systems and aquifers during its transfer to the oceans leads to predicted land water storage that are comparable to GRACE observations. Water stored in aquifers contributes about half the seasonal variation of water storage over large basins such as the Amazon, Congo, Yangtze, Ganges, Brahmaputra, and Mekong.
