Datasets of very high-degree surface load Love numbers and load Green's Functions for four elastic Earth models, globalc, oceanc, landc and REM1D
收藏资源简介:
In order to support load deformation studies for global, oceanic, and continental regions, the new reference model REM1D and the crustal model ECM1 are combined to construct three spherically layered elastic Earth models—’globalc’, ‘oceanc’, and ’landc’—each incorporating the average crustal physical structure of its respective region. Using the VSMS method, we computed surface load Love numbers (LLNs) up to degree 106 for the three models and ‘REM1D’ model (i.e., ocean-removed REM1D model) and derived the corresponding load Green’s Functions (LGFs) for ten geophysical quantities: radial displacement, tangential displacement, geoid change, gravity perturbation, gravity change, vertical deflection, tilt, radial strain, co-latitudinal strain, and longitudinal strain. High-degree LLNs pass asymptotic analytical solution tests. Here, we release comprehensive datasets for the three regionally adapted models (globalc, oceanc, landc) and the REM1D model, including surface LLNs from degree 0 to 106 and LGFs for ten physical quantities under CE, CM, CF, CL, and CH reference frames. These datasets for the globalc, oceanc and landc models provide new, complete, and high-quality fundamental parameters for surface load deformation research across global, oceanic, and continental scales. The LLNs and LGFs datasets from the REM1D model can provide a valuable reference for the three aforementioned models or serve as a benchmark for simulation studies. The elastic Earth models, simulation methods, and features of the results are described in the following two submitted manuscripts: Wang, H., Cheng, G., Xiang, L., Jiang, L. & Shen, Q. (2026).
