pyrex.earth = <pyrex.earth_model.PREM object>

Class describing the Earth’s density.

Uses densities from the Preliminary reference Earth Model (PREM).

Notes

The density calculation is based on the Preliminary reference Earth Model [1].

Attributes

earth_radiusfloat

Mean radius of the Earth (m).

radiituple

Boundary radii (m) at which the functional form of the density of the Earth changes. The density function in densities at index i corresponds to the radius range from radius at index i-1 to radius at index i.

densitiestuple

Functions which calculate the density of the Earth (g/cm^3) in a specific radius range as described by radii. The parameter of each function is the fractional radius, e.g. radius divided by earth_radius. Scalar values denote constant density over the range of radii.
