(2021) “Anelasticity and lateral heterogeneities in Earth’s upper mantle: impact on surface displacements, self-attraction and loading and ocean tide dynamics”, the global amplitude and root-mean-square fields of surface vertical displacement and self-attraction and loading due to ocean tide loading - the M2 tide derived from model TiME (Sulzbach et al., 2021), and the root-mean-square fields of M2 tide are presented here. The fields have been calculated for the 1D elastic solid Earth model PREM and 3D and 1D anelastic models. Figures 4-7, S1 and S2, and tables 1-2 in Huang et al. (2021) can be easily reproduced from these data fields applying the calculus discussed in the paper.

The anelastic Earth models can be constructed with the methodology outlined in Huang et al. (2021) by making use of the elastic and attenuation tomography models from the University of California, Berkeley (Karaoğlu, H. & Romanowicz, B., 2018) and the École Normale Supérieure (ENS) de Lyon (Debayle et al., 2020), respectively. All response fields (U and SAL) are calculated with the spectral-finite element method (Martinec 2000, Tanaka et al. 2019).
The response field - vertical displacement (U) and self-attraction and loading (SAL). The global amplitude and root-mean-square fields of U and SAL are given on a grid of 0.25°x 0.25° for the ucb (short for the University of California, Berkeley) and lyon (short for the École Normale Supérieure (ENS) de Lyon) models, respectively.

The tidal forcing - ocean tide model TiME is based on the elastic Earth model PREM and is published in Sulzbach et al. (2021, https://doi.org/10.1029/2020JC017097). The data is provided in https://doi.org/10.5880/GFZ.1.3.2021.001. Here only the root-mean-square fields of M2 tide between the 1D anelastic model and PREM, and those between the 3D and 1D anelastic model are provided.
