Core-mantle boundary (CMB) topography data
Masaki Yoshida
(1) Data from seismological analyses (four studies)
- Spherical harmonic coefficient data
- Models MD87, DH89, SH03, Tn10 (CMB_seis_sph.zip [2KB])
- Grid data (Grid points are 200 in latitude and 400 in longitude.)
- Models MD87, DH89, SH03, Tn10 (CMB_seis_grid.zip [2.1MB])
- *Data row: 1:longitude (0 to 360), 2:latitude (90 to -90), 3:topography [km]
