Determination of the height of Mount Everest using the shallow layer method
Geodesy and Geodynamics, 2021 Shallow layer method (SLM) based on the definition of the geoid can determine the gravity field inside the shallow layer. In this study, the orthometric height of Mount Everest (HME) is calculated based on SLM, in which the key is to construct the ...

Assessment of hybrid geoids in Chile and Spain, combining GGM and GNSS/Leveling observations
Geodesy and Geodynamics, 2021 This research presents the results for analyses done to five geopotential global models (GGM), comparing them with ground data from GNSS and leveling in heterogenic zones from the geodetic perspective, in Chile and Spain.

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 7, July 2023., 2023 Abstract Space gravity measurements have been mainly used to study the temporal mass variations at the Earth's surface and within the mantle. Nevertheless, mass variations due to the Earth's core might be observable in the gravity field variations as measured by Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On satellites.

Terra Nova, Volume 35, Issue 2, Page 83-90, April 2023., 2023 Abstract The crustal density structure in the Tarim Basin, NW China in response to the plate flexure is so far poorly constrained. We present new insights into the crustal density structure of the Tarim Basin using gravity/GNSS data from 728 mobile stations.
