Introduction

SPECFEM3D_GLOBE simulates global and regional (continental-scale) seismic wave propagation. Additional new model routines are provided for the Comprehensive Earth Model (CEM) project, generic point-profile models (PPM) and Gauss-Lobatto-Legendre based models (GLL), with complementary tools for postprocessing adjoint sensitivity kernels and gradient-based model updates. The structure of the software has been simplified to facilitate easier implementation of new 3D models. The code accommodates general moment tensor files, and provides complete information in the SAC headers, as explained in detail in the updated user manual. Loop-vectorization helps reduce the total number of memory accesses performed in each spectral element and improve code vectorization, enhancing numerical performance of the version.
