This data set contains the monthly Global Ocean Mass Anomalies (goma) since 04/2002, as measured by the GRACE and GRACE Follow-On (G/GFO) satellite missions. The data are averaged over the global ocean domain, at monthly intervals (note: data gaps exist). This file contains the goma time series based on the spherical harmonic gravity fields provided by the G/GFO SDS centers: JPL, CSR, GFZ. The data are frequently updated as new monthly observations are acquired by the GFO mission. The processing of the spherical harmonics gravity field coefficients is as follows: (1) GAD + GSM: the monthly de-...本数据集收录了自2002年4月起，由重力恢复与气候实验（GRACE）及其后续任务（GRACE Follow-On, G/GFO）卫星探测得到的逐月全球海洋质量异常（Global Ocean Mass Anomalies, 简称goma）数据。数据以全球海洋区域为平均计算范围，按月度间隔生成（注：存在数据缺失情况）。本文件包含基于G/GFO SDS中心提供的球谐重力场（spherical harmonic gravity fields）生成的goma时间序列，涉及的合作中心包括喷气推进实验室（Jet Propulsion Laboratory, JPL）、德克萨斯大学空间研究中心（Center for Space Research, CSR）以及德国地学研究中心（GeoForschungsZentrum Potsdam, GFZ）。随着GFO任务获取新的月度观测数据，该数据集将得到持续更新。球谐重力场系数的处理流程如下：(1) GAD + GSM：月度去...
