| Short Description | The second-generation Collaborative Seismic Earth Model (CSEM2) is a global, multi-scale Earth model developed using full-waveform inversion. The term ‘multi-scale’ reflects the varying sizes of the inversion domains. CSEM2 integrates information from both global and regional inversions into a unified framework. This file contains the regional extraction of CSEM2 in Europe, where contributing submodels are by Fichtner et al. (2013), Rickers et al. (2013), Fichtner and Villaseñor (2015), Çubuk-Sabuncu et al. (2017), Blom et al. (2020) and van Herwaarden et al. (2023). For user-specific domains and spatial resolution of CSEM2, please contact the author. This submodel has been extracted from the variable-parameterisation CSEM onto a regular grid, readable by EMC tools. |
