Summary
LITHO1.0 (Pasyanos, Masters, Laske and Ma, 2014) is a 1° tessellated model of the crust and uppermost mantle of the earth, extending into the upper mantle to include the lithospheric lid and underlying asthenosphere. The netCDF version provided by EMC is a 1°-by-1° grid representation of LITHO1.0 model.

Short Description |
The LITHO1.0 model (Pasyanos, Masters, Laske & Ma, 2014), is a 1° tessellated model of the crust and uppermost mantle of the earth, extending into the upper mantle to include the lithospheric lid and underlying asthenosphere. The model is parameterized laterally by tessellated nodes and vertically as a series of geophysically identified layers, such as water, ice, sediments, crystalline crust, lithospheric lid, and asthenosphere. LITHO1.0 was created by constructing an appropriate starting model, including CRUST1.0 as starting model for the crust. We then perturbed the model to fit high-resolution surface wave dispersion maps (Love, Rayleigh, group, phase) over a wide frequency band (5-40 mHz). Each of the nodes has a unique profile where the layers are:

Usage Notes | Each layer in this model is represented by a single 2D variable (see LITHO1.0.nc metadata). |

A compressed tar file containing the model in its native format and C++ source code to read it at any arbitrary location (access_litho). The C++ source code should compile with any standard compiler. LITHO1.0.nc is the netCDF file for the above model on a 1°-by-1° grid. See LITHO1.0 metadata for a complete list of the model variables. |
