REM-3D is a project funded by the National Science Foundation and carried out by Raj Moulik, Ved Lekic, Barbara Romanowicz, and Adam Dziewonski.

The aim of the project is to develop a three-dimensional seismic reference model (REM-3D) for the Earth’s mantle, parameterized in terms of shear wavespeed (Vs), compressional wavespeed (Vp), density (ρ), and the 3 additional parameters representing radial anisotropy. Unlike previous reference models of Earth structure, REM-3D will come with uncertainty estimates. You can read more about REM-3D here.
