WHU-CASM-UGM2025 The combined global gravity field model up to degree and order 11000

WHU-CASM-UGM2025 is a combined global gravity field model up to degree and order (d/o) of 10799 in spheroidal harmonics and 11000 in spherical harmonics, developed by Wuhan University and Chinese Academy of Surveying and Mapping. It is based on XGM2019e, and augmented by ultra-high resolution topographic potentials and altmetry products.
