Moho topographic grid data

Grid data and maps of Moho topography related to crustal thickness model of Ishihara et al. (2009).

The Moho model is created with the condition that the Bouguer gravity anomaly is explained by Moho topography without having the mantle exposed at the lunar surface. We used SGM100g gravity field model, STM359_grid-03 topography model. Assumed densities of the crust and the mantle are 2800 kg/m3 and 3360 kg/m3, respectively. The mare basalt layer with a density of 3200 kg/m3 has been taken into account. The Moho topography is described with respect to a sphere with 1737.4 km radius. Unit is in km.

The map is centered on 270 degree east longitude, with the nearside on the right and the farside on the left.
