This contribution provides a comparison between the Gaussian and decorrelation filters as derived from GRACE products (RL05) estimated by the official GRACE Science Data System centres (GFZ, CSR and JPL) as well as the ITSG-GRACE2016 solutions over Egypt. The outcome of this study will help in finding out which of these centres provides improved temporal gravity solutions as well as the most promising GRACE time series over Egypt. The obtained results regarding Gaussian filters show that the GFZ centre provides the most promising solutions w.r.t. CSR and JPL. Whereas the ITSG-GRACE2016 products provide improvements, especially at Gaussian radius 200 km, of about 56%, 68% and 60% w.r.t. CSR, JPL and GFZ solutions, respectively. Regarding the decorrelation filtering, the ITSG-GRACE2016 provides the least Std. w.r.t. CSR, JPL and GFZ solutions showing for the DDK8 improvement of about 48%, 64% and 68% w.r.t. the three centres GFZ, JPL and CSR, respectively.

该贡献提供了高斯和去相关滤波器之间的比较，这些滤波器源自官方 GRACE 科学数据系统中心（GFZ、CSR 和 JPL）估计的 GRACE 产品（RL05）以及埃及的 ITSG-GRACE2016 解决方案。这项研究的结果将有助于找出这些中心中的哪些提供了改进的时间重力解决方案以及埃及最有希望的 GRACE 时间序列。获得的关于高斯滤波器的结果表明，GFZ 中心提供了 CSR 和 JPL 最有希望的解决方案。而 ITSG-GRACE2016 产品在 CSR、JPL 和 GFZ 解决方案方面分别提供了大约 56%、68% 和 60% 的改进，特别是在高斯半径 200 公里处。关于去相关滤波，ITSG-GRACE2016 提供的 Std 最少。关于企业社会责任，
