全球海洋平均质量变化的时间序海洋、冰和水文等效水高数据集

Tellus Level-4 Antarctica Mass Anomaly Time Series from JPL GRACE/GRACE-FO Mascon CRI Filtered Release 06.1 version 03

从 JPL GRACE/GRACE-FO Mascon CRI 过滤发布的 Tellus Level-4 南极洲质量异常时间序列 06.1 版本 03

简介

该数据集是全球海洋平均质量变化的时间序列。它提供了非星际或仅质量的海平面随时间的变化。质量变化来自 JPL GRACE Mascon 海洋、冰和水文等效水高 CRI 滤波 RL061Mv03 数据集，该数据集可在 https://podaac.jpl.nasa.gov/dataset/TELLUS_GRAC-GRFO_MASCON_CRI_GRID_RL06.1_V3 上找到。关于 Mascon 解决方案的更详细说明，包括数学推导、地球物理约束的实施以及解决方案的验证，请参见 Watkins 等人，2015 年，doi: 10.1002/2014JB011547。质量变化以 ASCII 表格形式提供。
