Grid data of crustal thickness model


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

The crustal thickness 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 thickness of the mare basalt layer is included in the modeled crustal thickness.

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