title: Solutions of ocean tide loading displacement, self-attraction and loading and ocean tides for an advanced 3D anelastic solid Earth model

description: As a supplement to Huang et al. (2022) “The influence of sediments, lithosphere and upper mantle (anelastic) with lateral heterogeneity on ocean tide loading and ocean tide dynamics”, we provide for the advanced earth model LH-Lyon-3Dae [consisting of 3D elastic sediments, lithosphere and 3D anelastic upper mantle structures, see Huang et al.(2022) for details] the solutions of vertical ocean tide loading (OTL) displacement, self-attraction and loading (SAL) elevation, and ocean tides. Solutions for three tidal constituents, i.e., M2, K1 and Mf, are given. As a comparison, solutions based on the 1D elastic model PREM and the 1D anelastic LH-Lyon-1Dae are also presented. With these solutions, the primary results in Huang et al. (2022) such as the model amplitude differences, RMS differences and the predictions in GNSS stations can be reconstructed.
description: The vertical OTL displacement and SAL elevation are given in terms of the amplitude on a global grid of 0.1 x 0.1 degrees for PREM, LH-lyon-1Dae and LH-Lyon-3Dae. The ocean tide is given in terms of in-phase and quadrature components on a global grid of 0.1 x 0.1 degrees for PREM, LH-lyon-1Dae and LH-Lyon-3Dae. The tidal solutions are based on an original ocean tide model TiME (0.083 x 0.083 degrees), which is published in Sulzbach et al. (2021) with data provided in Sulzbach et al. (2021). All datasets are provided in a NetCDF format and can be viewed by the tool ncview. Data manipulation can be achieved by using the Generic Mapping Tools (GMT), CDO and NCO commands. The files included in the data publication are: • M2_LH-Lyon-3Dae.nc – the NetCDF file showing the in-phase and quadrature components of the M2 tide, and the amplitudes of M2 OTL displacement and SAL elevation for LH-Lyon-3Dae; • M2_LH-Lyon-1Dae.nc – the NetCDF file showing the in-phase and quadrature components of the M2 tide, and the amplitudes of M2 OTL displacement and SAL elevation for LH-Lyon-1Dae; • M2_PREM.nc – the NetCDF file showing the in-phase and quadrature components of the M2 tide, and the amplitudes of M2 OTL displacement and SAL elevation for PREM; • K1_LH-Lyon-3Dae.nc – the NetCDF file showing the in-phase and quadrature components of the K1 tide, and the amplitudes of K1 OTL displacement and SAL elevation for LH-Lyon-3Dae; • K1_LH-Lyon-1Dae.nc – the NetCDF file showing the in-phase and quadrature components of the K1 tide, and the amplitudes of K1 OTL displacement and SAL elevation for LH-Lyon-1Dae; • K1_PREM.nc – the NetCDF file showing the in-phase and quadrature components of the K1 tide, and the amplitudes of K1 OTL displacement and SAL elevation for PREM; • MF_LH-Lyon-3Dae.nc – the NetCDF file showing the in-phase and quadrature components of the Mf tide, and the amplitudes of Mf OTL displacement and SAL elevation for LH-Lyon-3Dae; • MF_LH-Lyon-1Dae.nc – the NetCDF file showing the in-phase and quadrature components of the Mf tide, and the amplitudes of Mf OTL displacement and SAL elevation for LH-Lyon-1Dae; • MF_PREM.nc – the NetCDF file showing the in-phase and quadrature components of the Mf tide, and the amplitudes of Mf OTL displacement and SAL elevation for PREM.
