Description
1) DensityGrid.dat = map of density of pore-free surface rocks (Figure 1a)
- Units = g/cm3
- 720 x 1440 pixels corresponding to 0.25-degree pixels in an equirectangular cylindrical projection with the equator as central parallel.
- The first row represents 90 to 89.75 degrees of latitude north; the last row represents 89.75 to 90 degrees of latitude south.
- The first column represents 0 to 0.25 degree of longitude; the last column represents 359.75 to 360 degrees of longitude.
2) MeltGrid.dat = map of degree of partial melting (Figure S1a)
- Units: mass fraction
- 720 x 1440 pixels as described above
3) CrustalThickness_ModelU0.dat = map of crustal thickness if laterally uniform density, Model U0 (Figure 2a)
CrustalThickness_ModelVn.dat = map of crustal thickness if laterally variable density, Model Vn (Figure 2c, Figures S6 to S10)
- Units = km
- generated with MakeGridDH of SHTOOLS (https://shtools.github.io/SHTOOLS/)
- 720 x 1440 coordinate points corresponding to 0.25-degree spacing in an equirectangular cylindrical projection with the equator as central parallel.
- The first row corresponds to 90 degrees of latitude north; the last row corresponds to 89.75 degrees of latitude south.
- The first column corresponds to 0 degree of longitude; the last column corresponds to 359.75 degrees of longitude.
