Evaluation of Gravity Data by EIGEN-2 (CHAMP-only) Model in ChinaEIGEN-2 may have inferior estimates. The evaluation of the terrestrial gravity data for China and its vicinities by comparisons with the models of CHAMP has confirmed the existence of larger errors and systemic discrepancy.Alpha-Cells 发表于 2025-3-27 04:06:12
sets of the mission. The main outcome of this expert meeting is summarized in this volume. The book offers a comprehensive insight into the present status of the exploitation of CHAMP data for Earth system research and practical applications in geodesy, geophysics and meteorology..978-3-642-43736-6978-3-540-26800-0Fatten 发表于 2025-3-27 06:37:12

However the CHAMP models continue to show improved resolution as more and better (e.g. lower elevation) data are incorporated. The best CHAMP models agree w抑制 发表于 2025-3-27 12:40:35

CHAMP Gravity Field Solutions and Geophysical Constraint Studiessemi-annual and annual components. It is shown that CHAMP temporal gravity solution agrees well with the SLR solutions as well as various geophysical fluid models, including atmosphere, hydrology, and ocean. The correlation coefficients between CHAMP and SLR solutions are 0.6∼0.8, with RMS at 0.7∼0.正式通知 发表于 2025-3-28 08:24:20
Application of Eigenvalue Decomposition in the Parallel Computation of a CHAMP 100x100 Gravity Fieldorm minimization, and finding the minimum trace of the mean square error (MSE) matrix. Analysis of the five different EVD gravity fields was performed. Two of them were shown to be comparable to the EIGEN1S CHAMP solution obtained by the GeoForschungsZentrum Potsdam (GFZ) {xc}.

Time-Variable Gravity Seen by Satellite Missions: On its Sampling and its Parametrization These issues suggest that an adequate parametrization of the gravity field as a function of space and time needs further study. Eigenvalue analyses of solution normal matrices may be a useful tool for these studies.
