Improvements in the Monthly Gravity Field Solutions Through Modeling the Colored Noise in the GRACE Data

摘要

Abstract >The Gravity Recovery And Climate Experiment (GRACE) mission has achieved a quantum leap in knowledge of the Earth's gravity field. However, current gravity field solutions still cannot reach the prelaunch baseline accuracy. One of the reasons for that is the presence of colored noise in GRACE data, which is typically ignored in the classical dynamic approach to gravity field modeling. In this research, we propose to account for colored noise in the classical dynamic approach by applying the frequency‐dependent data weighting (FDDW) scheme, so that enhanced estimates of gravity field solutions are produced. The monthly solutions are compared with those produced using the standard least squares adjustment without a data weighting scheme. The comparison is performed in both spectral and spatial domains, showing the positive effect of the FDDW scheme in all considered cases. For instance, the cumulative geoid height errors up to degree 96 are reduced by 18%. In the spatial domain, the FDDW scheme lowers noise level in mass changes over the oceans, Mississippi river basin, and Greenland by 20, 38, and 23%, respectively, when compared to the without a data weighting scheme. In addition, the consistency of mass changes over the Mississippi and Congo river basins with those inferred from the state‐of‐the‐art hydrology model WaterGAP is substantially improved when the FDDW scheme is applied. These results indicate that modeling colored noise in the GRACE data allows to significantly improve the recovered monthly solutions. This finding is likely applicable also to the GRACE Follow‐On mission. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >重力恢复和气候实验（Grace）任务已经实现了一种巨大的知识地球的重力场。但是，目前的重力场解决方案仍无法达到预先加速基线精度。其中一个原因是宽限数据中彩色噪声的存在，这通常在传统的重力场建模中忽略了典型的动态方法。在本研究中，我们提出通过应用频率相关的数据加权（FDDW）方案来考虑经典动态方法，从而产生了增强的重力场解决方案的估计。将每月解决方案与使用具有数据加权方案的标准最小二乘调整产生的那些进行比较。比较在光谱和空间域中进行，显示FDDW方案在所有所考虑的情况下的正效应。例如，高达96度的累积大型水大型高度误差减少了18％。在空间域中，与没有数据加权方案相比，FDDW方案分别降低海洋，密西西比河流域和格陵兰岛的大规模变化的噪声水平。此外，当施用FDDW方案时，基本上改善了密西西比和刚果河盆地的群众变化的一致性与从最先进的水文模型水涂层推断。这些结果表明，宽限数据中的彩色噪声建模允许显着提高恢复的月度解决方案。这一发现可能也适用于恩典后续任务。</ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-34677/'>《Journal of geophysical research.
