Abstract

The HUST-Grace2020 model is the latest GRACE-only gravity field solution developed at Huazhong University of Science and Technology. The model includes a set of spherical harmonic coefficients with different maximum degrees (60 and 90), and they are all unconstrained solutions. During retrieving our model, the reprocessed GRACE L1b RL03 data is used, and the newly de-aliasing product AOD1B RL06 is applied. Further details are presented in Zhou et al. (2018, 2019).
