PREM meaning in Academic & Science ?

Answer: What is Preliminary Reference Earth Model mean?

The preliminary reference Earth model (PREM) is a one-dimensional model representing the average Earth properties as a function of planetary radius. It includes a table of Earth properties, including elastic properties, attenuation, density, pressure, and gravity, as a function of planetary radius.

PREM has been widely used as the basis for seismic tomography and related global geophysical models. It incorporates anelastic dispersion and anisotropy and therefore it is frequency-dependent and transversely isotropic for the upper mantle.

PREM was developed by Adam M. Dziewonski and Don L. Anderson in response to guidelines of a "Standard Earth Model Committee" of the International Association of Geodesy (IAG) and the International Association of Seismology and Physics of the Earth's Interior (IASPEI) Other Earth reference models include iasp91 and ak135.
