|Depth Coverage||0-100 km|
|Area||The southern part of eastern North America margin (latitude: 30.56°/39.5°; longitude: 277.5°/289.46°)|
|Data Set Description||SENAM_FWT_2021_0.020.nc includes latitude, longitude, depth, and absolute S-wave velocity in eastern North America. The model was parameterized into a regular 0.020-degree horizontal grids in longitude and latitude directions. The vertical grid size increases with depth from one-third of the horizontal grid size for the top 15 km to ~2 km at 100 km depth.|
