Progress of Research on the Earth's Gravity Tides and its Application in Geodynamics in China.

High-precision gravity measurements provide an invaluable approach for exploring the interior of the Earth by detecting geodynamic phenomena generated by different physical processes. China has established a very extensive and diverse gravity observation network, including high-precision superconducting gravimeters, gPhones, and other kinds of gravity instruments. The observational data accumulated from these instruments over a long period has facilitated important achievements in a variety of geodynamic applications. This paper briefly introduces some recently important research progress in background noise analysis, gravity tides, liquid core dynamics, hum signal, and normal mode detection based on China's gravity network and its cooperation with the international gravity network.
