The gap-filling dataset for three GRACE/GRACE-FO mascon solutions

We use Singular Spectrum Analysis (SSA) to fill the gaps and provide users with continuous and complete mascon products. The dataset is used for three mascon datasets: the CSR mascon solution RL06.2, the JPL mascon solution Coastal Resolution Improvement (CRI) Filtered RL06.1v03, and the GSFC RL06v2.0 mascon solution. The singular spectrum analysis method supporting this study is available at https://doi. org/10.1029/2020JB021227.本研究采用奇异谱分析（Singular Spectrum Analysis, SSA）填补数据间隙，为用户提供连续完整的质量浓度块（mascon）产品。本数据集可适配三类mascon数据集：分别为CSR RL06.2版本mascon解、JPL经海岸分辨率改进（Coastal Resolution Improvement, CRI）滤波的RL06.1v03版本mascon解，以及GSFC RL06v2.0版本mascon解。支撑本研究的奇异谱分析方法相关资料可通过链接https://doi.org/10.1029/2020JB021227获取。
