填隙数据集包含三个 GRACE/GRACE-FO mascon 解

我们采用奇异频谱分析方法填补了三种 mascon 产品中 GRACE 和 GRACE-FO 数据集之间的空白，并在线提供了插值 mascon 数据集。GRACE/GRACE-FO的三个解决方案分别是CSR RLO6.2、GSFC RLO6v2.0和JPL CRl Filtered RLO6.1v03，分别由CSR、JPL和GSFC开发。经过一系列校准后，Mascon解决方案以等效水厚度为单位提供储水异常。支持本研究的奇异频谱分析方法可在 https://doi.org/10.1029/2020jb021227。<br>

We utilized Singular Spectrum Analysis (SSA) to fill the temporal gap between GRACE and GRACE-FO datasets across three mascon products, and publicly released the interpolated mascon dataset online. The three solutions for GRACE/GRACE-FO are CSR RLO6.2, GSFC RLO6v2.0, and JPL CRl Filtered RLO6.1v03, which were developed by CSR, JPL, and GSFC, respectively. After a series of calibrations, these mascon solutions provide water storage anomalies in units of equivalent water thickness.
