Topography of the core-mantle boundary and lateral homogeneity of the liquid core

Topography of the core-mantle boundary and lateral homogeneity of the liquid core

Separate inversions of travel-time residuals of waves reflected from and transmitted through the core-mantle boundary yeild similar results in terms of spherical harmonic expansion of its topography up to degree and order 4. The theory is discussed.
