Global ultralow-velocity zone properties from seismic waveform modelling (NERC Grant NE/R012199/1)
Open source modeling code, with which all data were generated: https://github.com/kuangdai/AxiSEM-3D This code was primarily developed within the NERC-funded project, and used for a at least 10 publications over the past two years: [1] Wolf, Long, Leng, Nissen-Meyer.
