Description
| Name | MESWA |
| Title | A 3-D adjoint waveform tomography model for the Middle East and Southwest Asia |
| Type | 3-D Tomography Earth Model |
| Sub Type | Full waveform model including wavespeed, density and attenuation |
| Year | 2023 |
| Data Revision | r0.1 (revision history) |
| Short Description | MESWA is a model of radially anisotropic crustal and upper mantle seismic structure of the Middle East and Southwest Asia (MESWA) from adjoint waveform tomography. MESWA provides improved waveform fits in the period band 30-100 seconds relative to the starting and several other models (Rodgers, 2023a). |

Revision History
r0.0: uploaded August 7, 2023.
r0.1: uploaded March 4, 2024. The revised model (r0.1) corrects an error with the latitude values. The original version (r0.0) provided values on a geocentric coordinate system, while this revision provides the model with regular geographic latitudes. The difference shifts the model northward by at most about 0.2 degree.
