We validate the spectral-element method for seismic wave propagation in spherically-symmetric global Earth models. We also include the full complexity of 3-D Earth models, i.e., lateral variations in compressional-wave velocity, shear-wave velocity and density, a 3-D crustal model, ellipticity, as well as topography and bathymetry. We also include the effects of the oceans, rotation, and self-gravitation. For the oceans we introduce a formulation based upon an equivalent load, in which the oceans do not need to be meshed explicitly. Some of these effects, which are often considered negligible in global seismology, can in fact play a significant role for certain source-receiver configurations. Anisotropy and attenuation are also incorporated...
