Abstract: Since 1985, about 35-year high-precision gravity data have been being well accumulated and worldwide cooperation was effectively carried out. The unique international tidal gravity reference in Asia was established. The background noise model for low frequency in Chinese continent was constructed. A global experimental model and an accurate correction model in Chinese continent for gravity tides of the Earth were both constructed. The theoretical simulation of the effect of surface mass loading on gravity was improved. The signals related to the nearly diurnal resonance, Earth’s free oscillation and translational wobble of the Earth’s inner core were detected to investigate the physical parameters of the Earth’s deep interior. A theory which couples temperature into elastic deformation of a layered and self-gravitating spherical Earth was proposed. The above mentioned achievements would contribute to national precise surveying and mapping, global large-scale geodynamics and space techniques as roles of new instructions and/or references.

Abstract: Remote sensing of cryosphere, as an important branch of cryospheric science, is a new interdiscipline, involving the knowledge of both cryospheric science and remote sensing techniques. This paper overviews the objects and basic methods of cryospheric remote sensing, introduces the progresses by using representative case studies, and especially, describes the research status of Chinese cryospheric remote sensing. Finally, we propose several recommendations for the development of remote sensing of cryosphere. In particular, we discuss the potential paths to the scientific programme of Earth’s three poles.
